A-96.250.131 / 050220 7

2. Product Description

Application The AMI Turbitrace is used for the measurement of low level turbid-

ity in pure and ultra pure water.

Measuring

Principle

Turbidity is a measure of how much of the light traveling through

water is scattered by suspended particles. The scattering of light in-

creases with increasing suspended solid. The intensity of light scat-

tered at 90° as a beam of light passes through a water sample is

measured and indicates turbidity of the sample.

Signal

Outputs

Two signal outputs programmable for measured values (freely scal-

able, linear or bilinear) or as continuous control output (control pa-

rameters programmable).

Current loop: 0/4–20 mA

Maximal burden: 510 Ω

Third signal output available as an option. The third signal output

can be operated as a current source or as a current sink (selectable

via switch).

Relay Two potential-free contacts programmable as limit switches for

measuring values, controllers or timer for system cleaning with au-

tomatic hold function. Both contacts can be used as normally open

or normally closed.

Maximum load: 1 A / 250 VAC

Alarm Relay One potential free contact.

Alternatively:

 Open during normal operation, closed on error and loss of

power.

 Closed during normal operation, open on error and loss of

power.

Summary alarm indication for programmable alarm values and in-

strument faults.

Input For potential-free contact to freeze the measuring value or to inter-

rupt control in automated installations (hold function or remote-off).

Safety

Features

No data loss after power failure. All data is saved in non-volatile

memory. Over voltage protection of in- and outputs.Galvanic sepa-

ration of measuring inputs and signal outputs.

Communica-

tion Interface

(optional)

 USB Interface for logger download.

 Third signal output (can be used in parallel to the USB interface)

 RS485 with Fieldbus protocol Modbus or Profibus DP

 HART interface

AMI Turbitrace

Product Description

Measuring

Principle

The light beam emitted by the emitter LED [L] passes through the

sample and is received by the transmitted light beam sensor [J].

Some light will be scattered by particles contained in the sample

and received by the scattered light sensor [K], which is placed in a

90° angle to the emitter LED. The ratio between the signal strength

of the signal receiver and the reference receiver is a measure for

the turbidity of the sample.

On-line

Operation

The sample flows through the sample inlet [F] via solenoid valve

[G] and the manual 5 way valve [E] into the measuring chamber [B],

where the turbidity is measured. From there it flows through the

sample outlet [C] and the pressure regulator [K]. The pressure reg-

ulator is used to regulate the sample flow. Then the sample flows

via capillary [L] and flow meter [M] into the drain funnel [N].

To keep the measuring chamber clean and free from deposits it can

be cleaned by opening the drain valve [D].

2.1. Instrument Specification

CAUTION

The measuring chamber is under the pressure of the

sample line

If the inlet pressure is too high, moisture can enter the housing

of the measuring electronics and lead to incorrect measure-

ments and failure of the instrument.

 The maximum inlet pressure of 10 bar must never be

exceeded, not even for short time periods. Take appropriate

measures to protect the instrument from pressure surges in

the sample line.

3.3.3 Adjust the Sample Flow with a Capillary Tube

The AMI Turbitrace is as standard delivered with the capillary FEP

tube with an inner diameter of 1 mm and a length of 500 mm.

If you have a low sample pressure or you need a high sample flow,

a shorter capillary with 186 mm length can be used.

To replace the capillary proceed as follows:

1 Pull out the knob of the pressure regulator valve [A].

2 Close the valve.

3 Push in the knob to lock the valve in closed position.

4 Unscrew and remove the tube fittings [B] of the capillary [C].

5 Then screw in the tube fittings of the 186 mm capillary.

6 Tighten them well.

7 Open the pressure regulator valve.

The capillary tube determines the flow resistance and the maximal

flow rate. With the pressure regulator at the inlet side of the capil-

lary the flow rate can be adjusted within the given range, see dia-

gram below.

The standard capillary is an FEP tube with an inner diameter of

1 mm and length of 500 mm. If you have a low sample pressure or

you need a high sample flow, a shorter capillary with 186 mm

length can be used.
