VOLU-probe/2SS for Rectangular Ducts – Installation Procedure
INSPECTION & HANDLING. VOLU-probes 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 and weight 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.
ORIENTATION OF PROBES. Using the AIRFLOW directional arrow on the probe mounting flange to determine
correct orientation, install VOLU-probes with sensing holes facing airflow.

AIRBORNE CONTAMINANTS. The levels of air filtration and cleanliness associated with commercial HVAC
Systems, whether supply/return/exhaust/outside air, are satisfactory for operation of the VOLU-probe. Industrial
applications containing airborne contaminants may require periodic manual or automatic cleaning using
compressed air applied to the signal fittings, and/or removal from the duct or stack for physical cleaning.
MINIMUM REQUIREMENTS FOR INSTALLATION. Note: VOLU-probe locations shown are NOT ideal.
They indicate the minimum clearance required from air turbulence producing sources. Wherever possible, the
VOLU-probe should be installed where greater runs of straight duct (or clearances) than shown exist.

INSTALLING VOLU-probes. To achieve published performance standards, the location of VOLU-probes in
ductwork must comply with the Minimum Requirements for Installation (Page 2). VOLU-probes must be mounted
so that the sensing holes on the probes are at the center of equal areas in the duct. Refer to dimensions A and
B in Figure 1:
A = inside dimension (I.D.) of the duct wall on which the probes are to be mounted
B = dimension A divided by the quantity of probes furnished per location
Figure 1
The VOLU-probe/2SS is equipped with an integral mounting plate on one end and an adjustable end support
plate. See Details A and B.
Mounting plates are predrilled so they may be used as templates for drilling mounting holes.

FASTENERS. Gasket mounting surfaces should be clean and burr free. VOLU-probe mounting plates are
predrilled for 1/4" mounting fasteners. Air Monitor recommends the use of 1/4-20 bolts, nuts, and lock washers
(or flat washers and lock nuts). Fasteners should be stainless steel to be compatible with probes.
DIMENSIONAL SPECIFICATIONS.

THREAD SEALANT. Appropriate thread sealant should be selected depending on the maximum air temperature.
Use of high temperature pipe sealant at the probe signal fittings is recommended.
Teflon tape or equivalent products are not recommended for high temperature applications.

INTERCONNECTING TUBING. Refer to illustrations below for typical tubing configurations.
SIGNAL TUBING. Signal tubing for total and static pressure takeoff connections may be 1/4” O.D. if the
distance from the measuring device to the transmitter is 200’ or less.
