VOLU-probe/1SS 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.

INSTALLING VOLU-probes. To achieve published performance standards, the location of VOLU-probes in
ductwork must comply with the Minimum Requirements for Installation (Page 6). 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
VOLU-probe insertion and end support holes must be cut in the duct on the center lines shown in Figure 1.
Caution: VOLU-probe/1SS over 10 feet in length require mid-span support to eliminate excessive droop or
oscillation during operation.

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.
VOLU-probe/1SS
THREAD SEALANT.
Appropriate thread sealant should be selected depending on maximum air temperature. Use of a 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. Interconnecting tubing and fitting makeup is to be per Table 1 (see Page 5).
Refer to illustrations below for typical tubing configurations.

SIGNAL TUBING. Signal tubing commences at the total and static pressure takeoff connections at the center of
the interconnecting tubing array shown in Details B and C. Two signal tubing conditions are possible; tubing with
an AUTO-purge panel and tubing without an AUTO-purge or CAMS panel.
If an AUTO-purge panel or CAMS panel is not furnished, signal tubing for total and static pressure take-off
connections may be 1/4" O.D. if the distance from the measuring device to the transmitter is 200' or less.
If an AUTO-purge panel is furnished, the total and static pressure signal tubing should be sized per the following
Table:
It is not recommended that AUTO-purge panels be located more than 50 feet from takeoff connections. Signal
tubing from the purge panel to a transmitter should be sized 1/4" if the distance is 200' or less.
CAUTION:After tubing is completed, signal lines should be leak tested prior to operation. Care must be taken
not to overpressurize measuring device.

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.
