MT5100

Guided Wave Radar Level and Interface Transmitter

Thank you for using the K-TEK MT5100 Guided Wave Radar Liquid Level and Interface Transmitter. The MT5000

series is a second generation of products which have been designed for simplicity of setup while offering extensive

configuration capabilities. You are invited and urged to review this instruction manual in its entirety prior to use of

the transmitter. This will eliminate most installation problems due to improper configuration.

We, the K-TEK Family, sincerely hope you receive many years of reliable use from the MT5100 transmitter and

welcome your feedback to consistently improve our all of our products. It is our desire to provide you, the user, with

the most reliable, customer friendly device to suit your application needs.

When it comes to measuring the level of liquids, guided wave radar technology now offers more level-detection

capabilities than ever before. For an ever-widening range of previously hard-to-measure products such as molten

sulfur, liquid ammonia and petrochemicals, guided wave radar transmitters provide accurate level measurements

even under harsh chemical environments, wide variations in operating temperatures and pressures, and low

dielectric constants. Great strides have also been taken in making these units easier to configure to a variety of

process applications coupled with the simplicity of integrating these devices with most digital communication

protocols. These improvements come as a welcome relief to process engineers that seek solutions to measuring the

contents of tanks, silos, hoppers, bins, mixing basins, and vessels in an expanded range of level applications across

several different industries.

Because a guided wave radar transmitter has no moving parts, it has established itself as a level measurement

technology that has distanced itself from traditional mechanical means, which don't hold up as well in dirty service.

Guided wave radar achieves its non-mechanical level detection capability by measuring the time of flight of the

transmitted signal.

Known more accurately as Time Domain Reflectometry (TDR), the process involves:

1. Sending microwave energy down into a vessel guided by an antenna.

2. When the pulse of radar energy reaches the product (indicated by a change in impedance), part of the

pulse is reflected back toward the transmitter.

3. A receiver measures the exact duration of time between the transmitted and reflected signal—the "time

of flight."

4. The device analyzes this time and ultimately displays the level of the product as a distance in inches,

feet, meters, or other engineering units.

The MT5100 transmitter was developed with ease of operation in mind. We made use of a graphic display to

provide a more user friendly aspect to the transmitter configuration. The graphic display allowed us to incorporate

multiple language options in the setup menu such as English, Spanish and Chinese. In the incorporation of the

graphic display, the electronics were converted to a digital format. This provided a greater signal recognition

capability and an ability to include an “onboard oscilloscope” as an aid in troubleshooting tough applications.

The emphasis on simplicity extended itself beyond the use of multiple languages. The Basic Setup menu has been

designed with a series of multiple choice questions which, when answered correctly, will configure the transmitter to

the installation. The mA Output Setup menu has been expanded to include Loop Test and HART® Address

capabilities.

Coupled with the development of the MT5100 series was the development of the KCOM™ software. KCOM™ is a

diagnostic tool which allows the MT5100 to be remotely configured using a computer and HART® interface modem.

Beyond the Basic Setup parameters, the software will allow the user to view the return signal of the MT5100 on the

computer screen. As a trouble shooting tool, a screen shot of the waveform may be taken and sent to the factory for

analysis. The KCOM™ software is free and may be downloaded from our website at www.ktekcorp.com.

MT5100

Guided Wave Radar Level and Interface Transmitter

2. Overview

2.1 Storage and Handling Information

If possible, storage prior to installation should be indoors at ambient temperature, not to exceed the following:

Temperature range: -40 to 150 degrees F.

Humidity: 0 to 100% R.H. non-condensing.

To avoid probe damage:

Do not transport or support the weight of the MT5100 by means of the probe.

Installation of rigid probes and flange mounted transmitters may require the use of lifting equipment.

Avoid sharp bending of cable probes which can result in poor instrument operation.

The lids on the MT5100 housing are sealed with o-rings. To avoid damage to the electronics, both lids should be closed

tightly before and after installation.

2.2 Ambient Temperature

The MT5100 electronics temperature may not exceed 170°F / 77°C. For higher ambient temperatures due to radiant

process heat, a high temperature extension option is required. The coupler process temperature shall not exceed

the temperature stated in the datasheet specifications for the given coupler.

MT5100-0200-1 Rev b (2-2013) DCN0365 6

MT5100

Guided Wave Radar Level and Interface Transmitter

The MT5100 is a 4-20mA loop powered Smart Level Transmitter, which is microprocessor based and is available

with HART® communication. It uses very low power microwave energy to determine the level or interface of the

products being measured. In order to obtain optimum performance, it is important to understand the basic principle

of operation. The electronics housing is fitted with a special adapter “Coupler” serving as a process connection and

seal, which holds a solid rod or a cable. The rod or cable “Probe” hangs into the vessel and acts as a wave-guide,

i.e. the probe guides the microwave energy to the product surface, instead of being dispersed in a cone, as it would

be if there was no probe.

A measurement cycle consists of the following:

1. A very short “pulse” of microwave energy is applied at the

coupler, to the Probe.

2. The pulse travels along the length of the probe and when it

encounters a discontinuity that is a dielectric constant change, at

the level surface, some of the energy is reflected and travels

back towards the coupler.

3. When the reflected energy from the level reaches the coupler, it

is sensed by the electronics. By measuring the time elapsed

between the initial pulse and the reflected one, the electronics

can calculate the level.

4. The energy not reflected by the level passes through the upper

fluid and is reflected at the interface level.

5. When the reflected energy from the interface level reaches the

coupler, it is sensed by the electronics. The electronics then

calculate the level of the interface using the known dielectric

constant and level of the upper fluid.

6. Since the microwave energy travels at the speed of light, one

complete measurement cycle is made up of several thousands

of Pulses. The electronics uses Time Domain Reflectometry

(TDR), a sampling technique to reconstruct a waveform for both

levels duplicating the actual real time signal, but at a much lower

speed, so that it can be processed by the microprocessor. This

process can be compared to using the stroboscope effect as

when observing a piece of machinery turning at high speed with

a strobe light.

7. The measurement cycles are made 2 times per second and are

processed by special filtering techniques, before generating a

current output proportional to the level or interface of the

products.

MT5100

Guided Wave Radar Level and Interface Transmitter

A simplified signal trace as seen on the graphic display (Figure 2.1) can be divided into three identifiable sections:

- Coupler Reflection.

- Level Reflection

- Interface Reflection

The measurement principle using TDR is based on the fact that a dielectric constant discontinuity or geometric

change will yield a positive pulse having certain amplitude above the baseline. The greater the dielectric constant

difference, the greater the positive amplitude of the return signal. This means that a signal will show up on the

baseline if there is a substantial change from a nozzle diameter to an open tank, for example, as signal plot at the

process connection. This fact will be taken into account in the configuration of the MT5100 (Consult Basic Setup

(Section 4.3 on Commissioning).

Note: Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired operation.

2.4 Total Level and Interface Measurement

1. If the application utilizes the “non-flooded chamber” menu selection, both the total level and the interface level

can be obtained from a single process connection when the MT5100 is utilized with a RI100 Repeat Indicator.

2. The MT5100 provides a 4-20 mA output representing the interface level while the RI100 provides a 4-20 mA

signal representing the overall level.

3. While this type of application works best with the MT5100 mounted directly on the vessel, an external chamber

with a minimum of three process connections can also be utilized as long as ONLY one interface level (liquid-

liquid or liquid-vapor) occurs between any two (adjacent) process connections.

4. See drawing ELE1004 in this manual’s appendix for the RI100 wiring diagram.

5. See the RI100 Data Sheet and consult K-TEK for additional information.

MT5100

Guided Wave Radar Level and Interface Transmitter

In order to properly detect the level of interface between two liquids using the MT5100, the following rules must be

adhered to:

1. One of the following probe and mounting configurations must be used:

a. Single rigid rod or flexible cable mounted in a stilling well, external chamber, or existing

displacer.*

 Minimum inside pipe diameter - 1.939 in. (2 in. sch. 80)

 Maximum inside pipe diameter - 4.26 in. (4 in sch. 10)

 For other pipe diameters, consult factory.

 Maximum probe length:

 Single rod - 20 ft.

 Flexible cable - 30 ft

b. Dual rigid rod or flexible cable

Maximum probe length

 Dual rigid rod - 20 ft

 Dual flexible cable - 65 ft

c. Coaxial probe mounted into tank, external chamber, or displacer

 Maximum probe length - 22 ft

 Both fluids must be clean

* This is the preferred mounting configuration to reduce the chance of fouling.

2. Emulsion layers will affect the detection of an interface level. An emulsion layer may negate an interface level

indication completely. The MT5100 will read an interface level in the presence of a 2 inch emulsion. The MT5100

is equipped with a weak interface signal detector (patent pending). This visual indication will let the user know

when an emulsion layer may be present.

3. The minimum upper fluid thickness must be 4 inches when emulsion is present, and 0 inches with a clean

interface.

4. The upper fluid dielectric constant must be greater than 1. 6 and less than 5.

5. The interface level indication is a calculated value based partially upon the dielectric of the upper fluid. The

upper fluid dielectric must remain constant for consistency / accuracy in the interface level indication.

6. The lower fluid dielectric constant must not be less than 15.

7. If the application is a flooded condition (sensor completely submerged in process), it must remain completely

flooded.

8. In a non-flooded condition, the upper fluid must not be allowed to enter the upper unmeasureable zone. The

upper unmeasureable zone is typically located within the mounting nozzle of the vessel.

If the required interface application does not fall within the above mentioned parameters, please consult the factory

for an alternate technology, such as a Magnetostrictive, Magnetic Level Gauge or RF Capacitance.

MT5100-0200-1 Rev b (2-2013) DCN0365 9

MT5100

Guided Wave Radar Level and Interface Transmitter

3.2 Mechanical Installation

1. Do not mount the MT5100 in the product fill stream.

2. To obtain the best return signal from the product level mount the MT5100 coupler directly into the top of the ves-

sel.

3. Do not mount MT5100 single probes using bushings. (Figure 3.1)

4. Ideally, probes should be mounted in the center of the vessel to provide the maximum measuring range.

5. Avoid internal obstructions such as tubing, ladders or agitators.

6. An MT5100 installed in a nozzle whose height is greater than its width will have an increased non-linear zone at

the top of the probe.

7. Cable probes with weights should be allowed to hang under the tension of the weight within the vessel. Shorten-

ing of the probe may be required.

8. To avoid excessive movement of the MT5100 probe in an agitated process, or where installation close to the

vessel wall is required, secure the bottom end of the probe to the vessel. Probes installed from top of the vessel

may require the use of a stilling well.

9. Probes installed in side vessel connections require additional probe support within the nozzle connection.

10. Threaded connections should be installed with thread sealant approved for use by the consumer. Flanged

connections should be made using materials (bolts, studs, nuts, and gaskets) and procedures (torque specifica-

tions) approved by the consumer.

3.2.1 All Installations

3.2.2 Plastic Tanks, Fiberglass Tanks, and Open Air Installations

Dual Probe transmitters should not be used to measure interface levels in non-metallic vessels or open air installa-

tions. Single probes in stilling wells or coaxial probes should be used to prevent interruptions in transmitter opera-

tion.

MT5100-0200-1 Rev b (2-2013) DCN0365 10

MT5100

Guided Wave Radar Level and Interface Transmitter

An MT5100 with a single probe directly inserted in the vessel can be used to measure interface level if a metal still-

ing well is also utilized. This stilling well may already exist, as part of the tank structure, or may be purchased with

the MT5100.

1. The inside diameter of the chamber must not be less than 1.939 inches, the equivalent of 2” schedule 80

pipe (Consult factory for smaller sizes).

2. The inside diameter of the chamber must not be greater than 4.26 inches, the equivalent of 4” schedule 10

pipe (Consult factory for larger sizes).

3. If a rigid type probe is used, a centering disc is required to center the probe in the chamber and provide an

end of probe target.

4. If a flexible type probe is used, a centering weight is required to straighten the cable, center the cable, and

act as an end of probe target.

5. The upper fluid must not be allowed to enter the unmeasureable zone. This can be accomplished by

keeping the dimension between the top edge of the highest stilling well hole and the face of the coupler

greater than the unmeasureable zone (Section 3.2.7).

The hole pattern of the stilling well will be critical in determining the accuracy and reliability of the interface

measurement. One of the following hole patterns must be present for an existing stilling well to be used with the

MT5100 interface option.

For some applications a simple pattern of three holes in the stilling well will be suitable. The top hole will allow the

vapor to enter the stilling well. The center and bottom holes will allow the fluids to enter and equalize, if they are

placed properly. This will work if the upper fluid level continuously covers the center hole. If the upper fluid level

were to rise or fall from the center hole, the upper fluid would be cut off from the probe and inaccurate measurement

would result.

MT5100

Guided Wave Radar Level and Interface Transmitter

An ideal installation involves the use of multiple holes along the length of the stilling well. This will allow both

products to flow freely over the entire length of the probe. A typical stilling well purchased from K-TEK will have 1”

holes placed at 1.5” centers down the length of the stilling well with the top edge of the highest hole at 6 inches form

the face of the coupler.

OIL

WATER

The presence of an emulsion layer in the interface process can create problems with the interface measurement. If

the emulsion layer is known to exist in a specific area in the length of the probe, the holes in the stilling well can be

drilled to minimize the effects of the emulsion layer.

OIL

WATER

EMULSION

If the nozzle dimension on the top of the vessel is not greater than 4”, an additional stilling well or coaxial type probe

must be used.

In all cases, the upper most hole in the side of the stilling well should be kept outside of the unmeasureable

zone (Section 3.2.7). Stilling wells purchased from K-TEK will have the above factors taken into account during

manufacture. If you cannot accept the terms listed above, consult the factory for an alternate solution.

MT5100-0200-1 Rev b (2-2013) DCN0365 12

MT5100

Guided Wave Radar Level and Interface Transmitter

6. A MT5100 Interface option, set for a flooded condition (Figure A), must always remain flooded. Should the

chamber become non-flooded during operation, the transmitter will return false indications which could result in

process upsets and hazardous conditions.

7. If the configuration is non-flooded (Figure B), the upper fluid must not be allowed to enter the unmeasureable

zone. This can be accomplished by keeping the dimension between the top process connection and the access

flange greater than the unmeasureable zone (Section 3.2.7).

If the External Chamber for the MT5100 is being supplied by K-TEK Corporation, all of the above factors will be

taken into account during the manufacture.

Some interface applications may contain emulsion layers that interfere with the operation of guided wave radar

transmitters. Installing the MT5100 in an external chamber will allow the process to settle within the chamber and

reduce the affects of the emulsion on the interface level signal.

The single probe MT5100 may be installed in an External Chamber in order to measure interface level. The External

Chamber may already exist or be purchased from K-TEK. There are some guidelines which must be followed in

order to maintain proper operation of the transmitter.

1. The inside diameter of the chamber must not be less than 1.939 inches, the equivalent of 2” schedule 80 pipe

(Consult factory for smaller sizes).

2. The inside diameter of the chamber must not be greater than 4.26 inches, the equivalent of 4” schedule 10 pipe

(Consult factory for larger sizes).

3. If a rigid type probe is used, a centering disc is required to center the probe in the chamber and provide an end

of probe target.

4. If a flexible type probe is used, a centering weight is required to straighten the cable, center the cable, and act as

an end of probe target.

5. Two process connection configurations are typical for external chambers used to measure interface level:

a. The first configuration (Figure A) has two process connections and is commonly used for flooded cham-

ber interface measurement. In this configuration, a vent line back to the process should be used to keep the

chamber flooded.

Figure B Figure A

OIL

WATER

Vent

Line

VAPOR

b. The second configuration (Figure B) has three process connections. The top connection allows the va-

por space to equalize within the chamber and can be used to measure both total and interface level.

This chamber design is less likely to become flooded due to the distance between the top process

connection and the face of the coupler.

3.2.4 Single Probes in External Chambers

MT5100-0200-1 Rev b (2-2013) DCN0365 13

MT5100

Guided Wave Radar Level and Interface Transmitter

Dual Probe options do not require the use of an additional stilling well for operation. If the process environment

requires the use of a stilling well to prevent movement, a single probe design with a metal stilling well will be

sufficient. If the transmitter is to be mounted in an external chamber or displacer, single probes or coaxial probes are

the preferred probe types.

When installing a dual probe into a vessel for level detection, there are several things to consider:

1. The probe should not be mounted in the path of the product stream entering the vessel.

2. The probe should not be mounted within 6 inches of any construction within the vessel including ladders,

weirs or internal piping.

3. Tanks constructed of concrete require probe mountings to be:

a. 1 ft. / 0.3 m from wall with up to 20 ft. / 6.1 m measuring length

b. 2 ft. / 0.61 m from wall over 20 ft. / 6.1 m measuring length

4. The face of the MT5100 mounting/launch plate on dual probe transmitters mounted in concrete vessels

should be even with the inner surface of the concrete roof.

5. Dual probe designs incorporate spacers to separate probes at an equal distance. These spacers are points

for potential bridging. If the fluids contain floating particles, paraffin or other matter, bridging between the

probes may result. Scheduled maintenance will be required to flush probes of potential buildup.

6. Dual probes installed with nozzle diameters smaller than nozzle heights may require the use of an extended

BLK parameter. Refer to Section 4.5 to adjust this parameter. Extending the BLK may result in a loss of

measurable range.

7. If the MT5100 is set up for a non-flooded condition, the upper product should not be allowed to enter the

upper unmeasureable zone Refer to Section 3.2.7.

If the MT5100 you have received has a dual probe configuration, and you cannot accept the terms listed above, con-

tact the factory for an alternate solution.

3.2.5 Dual Rod/Cable Probes

Coaxial type probes will provide the best return signals from interface levels but they are not the best probes for

most interface applications. Here are some things to be cautious of when using a coaxial type probe for level

measurement:

1. Coaxial type probes are rigid and designed as a one piece unit. In their construction, a rigid rod is mounted

inside a small tube which acts as an included stilling well. The internal rod is held in the center of the outer

tube using spacers. Care must be taken not to flex or stress the outer tube when installing a coaxial style

probe, particularly probes over 10 ft. This may cause damage to the spacers and lead to improper operation.

2. Coaxial probes are recommended for use in clean fluids only. This will apply to both the upper and lower

fluids being measured. If the fluids contain floating particles, paraffin or other matter, bridging or clogging

within the tube may result. Scheduled maintenance will be required to flush probes of potential build-up.

Single probe configurations are the preferred method for applications with potential build-up.

(Section 3.1)

3. It is acceptable to mount coaxial style probes within external chambers or displacers. While it is possible to

measure low dielectric upper fluids such as propane and butane using a single probe in a 2 inch chamber,

larger chamber sizes may require the use of coaxial probes (Section 3.5).

If the MT5100 you have received has a coaxial style probe, and you cannot accept the terms listed above, contact

the factory for an alternate solution.

3.2.6 Coaxial Probes

MT5100-0200-1 Rev b (2-2013) DCN0365 14

MT5100

Guided Wave Radar Level and Interface Transmitter

Each mounting configuration will be subject to certain Unmeasurable Zones at the top and bottom of the probe.

These unmeasureable zones are characterized as having non-linear readings and in some cases lack of indication.

Careful attention must be paid to the type of probe being used and the mounting configuration used for proper op-

eration of the MT5100.

Unmeasureable zones at the bottom ends of probes are typically small and should not affect transmitter operation

under normal conditions.

Unmeasureable zones at the top of the probes range in size from 0 inches to 4 inches depending upon the installa-

tion and probe type. In this area, the indicated level from the product can become non-linear and eventually disap-

pear. When using the MT5100 for interface measurement in a non-flooded configuration, if the upper fluid enters the

top unmeasureable zone, the transmitter will consider the interface reading to be both the total and interface meas-

urement. In a flooded configuration, the unmeasureable zones will only cause errors in the interface measurement.

The upper unmeasureable zone will typically be situated within a nozzle if the MT5100 is mounted directly into a

process vessel. Single probe MT5100s mounted in existing displacers may be subject to having the unmeasureable

zone within the measuring range. In these cases, a coaxial type probe or a single probe with an included stilling well

may be required. External chambers and stilling wells manufactured by K-TEK will be designed to keep the unmeas-

ureable zone outside of the required measuring length of the transmitter.

Dual probe MT5100s are subject to the greatest unmeasureable range and should be considered as a last resort for

measuring interface levels.

The MT5100 single rod and cable probe can be cut to length prior to installation. If shortening of the probe is neces-

sary, cut the rod or cable to the desired length using a hacksaw.

Shortening of coaxial probes or Tri-Band probes in the field is not recommended.

The centering disc or weight at the end of the probe must be reattached for proper operation.

The Probe Length parameter in the Basic Setup menu will need to be adjusted for the new probe length.

3.3 Shortening of Probe

Electrical connection to the MT5100 should approach the transmitter head from below the conduit opening to provide

a drain for moisture. Install conduit to ½” NPT port and run 18 gauge twisted, shielded pair to housing. Refer to

page 40 for typical loop wiring diagram and to page 38-39 for instructions applicable to intrinsic safety installation.

Apply loop power to the transmitter as follows:

Terminal Block + 14 VDC minimum to 36 VDC Maximum

Terminal Block - To control System Input

Ground Screw GROUND

Note: The “+Meter” and “-Meter” terminals are available to hook up a mA meter to monitor loop current, without

breaking the loop.

3.4 Electrical Installation

The housing cover can only be removed when the unit is installed in a non-hazardous area, when

installed with intrinsic safety barrier, or when power is removed from the transmitter.

When power is applied to an MT5100 series transmitter, the display will light up with a title screen which shows the

model type and the software revision. (Figure 4.1) This initial power up cycle will last for 3 seconds and the current

output of the transmitter will hold at 4.00 mA.

After the initial power up cycle, the display will change to show the Measured Level and the Current Output. The out-

put will also shift to the current corresponding to the level. (Figure 4.2)

By pushing the UP or Down button, the main display can be scrolled to display the level in terms of a percentage of

calibrated range (Figure 4.3) or in terms of a linearized / strapped measurement. (Figure 4.4)

4. COMMISSIONING

4.1 Display Operation

The MT5100 transmitter has been designed with a simple easy to follow setup menu. To make this unit operational,

at a minimum, the items in the BASIC SETUP menu must to be entered. If further setup is required, a Quick Calibra-

tion may be used or additional menu items will need to be entered.

The jumper switches are located on the face of the electronics module and can be set up as follows (Figure 4.4).

a. ALARM (Left Jumper)

Placing the jumper to the lower position causes the output to go to 21.00 mA when there is a loss of signal

or transmitter malfunction.

Placing the jumper to the upper position causes the output to go to 3.62 mA when there is a loss of signal or

transmitter malfunction.

The alarm output works in conjunction with the ALARM DELAY setting available in the mA OUTPUT menu.

The output will go to alarm state only if there is a loss of signal that lasts at least the duration of the alarm

delay. The alarm delay default value is two (2) seconds. For instance the output will hold the last measured

value if there is a loss of signal lasting less than two (2) seconds and will go into the alarm condition if the

loss signal exceeds two (2) seconds.

b. WRITE PROTECT (Right Jumper)

When the jumper is in the lower position the transmitter configuration cannot be changed manually or via

HART® communication. (Figure 4.4).

Placing the jumper in the upper position will allow the configuration parameters to be changed manually or

via HART® communication. (Figure 4.4).

4.1.2 PUSHBUTTONS

Three pushbuttons are located on the lower portion of the module faceplate (Figure 4.5). These buttons will be used

to navigate through the setup and configuration menu of the MT5100. Some operations will require the pushbuttons

to be used together or held for a period of time to affect a change.
