INSPECTION & HANDLING. The ELECTRA-flo Probe Arrays should be carefully inspected for damage prior to installation.

Report damage to your Freight Department, or contact delivery carrier.

Almost any means of handling can be utilized depending on the length of the probes. Probes may be handled

while in any position; however, it is important not to drop or mishandle the probes such that damage is done to the

sensing holes, tubular members, signal connection fittings, end studs, or mounting plates.

ELECTRA-flo Probe Arrays – Ultra – Installation Procedure

LOCATION OF PROBES.

• When installing the ELECTRA-flo probes, select a location that meets or exceeds the Minimum Installation

Requirements.

• When more than the combined upstream and downstream minimum requirement for undisturbed straight duct is

available, distribute the excess duct length in proportion to the minimum requirements.

• Avoid locating the probes where they will be exposed to condensing moisture, such as downstream of a coil or

humidifier.

• Contact Air Monitor's Applications Engineering Department for guidance when the intended installation location

does not meet the Minimum Installation Requirements.

MINIMUM INSTALLATION REQUIREMENTS.

Turbulent Airflow. The aerodynamic design of the ELECTRA-flo sensor aperture will permit accurate flow

measurement in the presence of moderate air turbulence. The distances from air turbulence producing fittings,

transitions, etc., shown below are required to assure accurate airflow measurement.

Stratified Airflow. The ELECTRA-flo should be mounted so that the probe crosses any stratified airflow - not

parallel to the flow. This mounting arrangement will permit the probe to sense the wide range of velocities present in

stratified airflow.

Airborne Contaminants. The levels of air filtration and cleanliness associated with commercial HVAC systems

are satisfactory for the ELECTRA-flo. Applications containing airborne contaminants or condensing moisture may

impair measurement accuracy and functionality.

Minimum Requirements. The ELECTRA-flo locations shown below are the minimum clearance required from

air turbulence producing sources. Wherever possible, the ELECTRA-flo should be installed where greater runs of

straight duct or clearances exist.

INSTALLATION CONFIGURATIONS. Depending upon the size of the duct, the quantity of probes will range

between one and four per probe array. Based upon the quantity of probes in a particular array, use one of the

following generic layouts for determining proper probe spacing and configurations.

GENERAL PROBE INSTALLATION

• All probes for an array are packaged together when shipped from the Factory. The probes and the transmitter for a

particular measurement location can be identified by means of the ESID # on the end of each probe, transmitter

package, and the transmitter itself.

• Each probe has an airflow arrow on the mounting plate to assist in correct installation relative to the direction of

airflow in the duct.

• For rectangular ducts, the standard arrangement is for the probe(s) to be mounted on the short side (height) of the

duct, with the probe(s) running parallel with the long dimension (width) of the duct. Refer to Page 3 to determine

probe spacing.

• For circular ducts with more than one probe, the probes must be staggered along the axis of the duct to provide

clearance as they cross over each other in the center. The radial dimension (R) on the outside of a duct of known

diameter (D) with N (quantity) of probes can be determined by the following formula:

• For probes larger than 72", do not attempt to install with just one person.

• For probes 96" or more in length, refer to the next page.

D14.3

R =

The ESID # on the Transmitter and on the Probe(s) must match.

DO NOT MIX AND MATCH

Confirm the number of Probes needed for each Transmitter by

referring to the provided Factory Set-Up Sheet.

CAUTION: DO NOT BEND PROBES

INSTALLING PROBES 96" OR MORE IN LENGTH

ELECTRA-flo probe arrays having probe lengths between 96" and 144" are provided with a probe center support

assembly to structurally support against the effects of gravity, vibration, and the force of the moving airflow.

All ELECTRA-flo probes must be handled carefully during installation to avoid damaging any of the thermal sensors.

Due to their greater cantilevered weight, larger probes will require two people during installation; one outside the duct

to insert the probe, and a second person inside the duct to support and guide the probe into its end support hole.

After the ELECTRA-flo probes are fully mounted in the duct, install the center support by connecting it to the

individual probes using the U-bolt hardware provided. The center support goes on the downstream side of the

ELECTRA-flo probes (see Figure below):

– CAUTION –

DO NOT ATTEMPT TO INSTALL ELECTRA-FLO PROBES

LARGER THAN 72" WITH JUST ONE PERSON.

SUPPORT CLAMP DETAIL

Tighten the self-locking nuts so the center support is firmly attached to the probe(s), but not so tight as to deform

either the center support or the probes. Slide the center support mounting brackets outward so they come in

contact with the duct walls, then secure in place with the end support screws provided.

Finally, position the center support so that the clearance between the center support and the duct wall is the same

at both ends, then tighten the mounting bracket bolts. See Figure below:

EXTERNALLY MOUNTED PROBES.

• Mounting requires a 1.25" hole on one side of the duct, and a 3/8" hole on the other side for the threaded end

support for ducts wider than 18". See Figure A below for mounting details.

Figure A

• External mount probes are shipped with a 1/4" thick neoprene mounting gasket.

INTERNALLY MOUNTED PROBES.

• Mounting requires a single 1/2" diameter hole to allow the signal cable to be run to the transmitter. See Figure B

below for mounting details.

CABLE CONNECTIONS.

• All cables to connect the probes and transmitter are included.

• All probes have integral cables terminated with positive locking plug-in connectors.

• The cable length on each probe has been Factory selected based upon size of the duct and the quantity of

probes. Cables connecting probe to probe will range in length from 2' to 5'. The one probe that connects to the

transmitter will have a standard length 10' cable, with optional 50' and 100' long cables.

• Multiple externally mounted probes connect to each other in a daisy chain methods, with the first or closest

probe in the chain connecting to the transmitter. See Figure below.

• Multiple internally mounted probes are connected in parallel to a central junction box mounted inside the duct,

with the junction box connecting to the transmitter. See Figure below.

ELECTRA-flo Probe Arrays – Ultra – Installation Procedure

TRANSMITTER INSTALLATION.

• The transmitter must be located so that the single cable from the probe array will reach the receptacle in the

bottom of the transmitter. Standard cable length is 10', with optional 50' and 100' cables available.

• Mount the transmitter to a vertical surface in an upright position. Avoid locations subject to excessive amounts of

vibration.

• The transmitter's enclosure has a NEMA 1 rating, requiring that it be mounted in a moderately clean indoor

environment with temperature ranges between –20ºF and 140ºF.

• Consult the ELECTRA-flo Transmitter O&M manual for details related to power and signal wire connections,

configuration options, and start-up.

• See drawings below for transmitter dimensions and installation clearances.
