Model 160GW Wireless Air Flow Grid
Specications - Installation and Operating Instructions
Bulletin TE-160GW
The Model 160GW Averaging Air Flow Grid is a wireless sensing instrument used
to measure face air velocity on grills, diffusers, registers, exhaust hoods, coils, lters,
dampers and similar restrictions. With its 16 sensing points, the 160GW Air Flow Grid
provides an average ow sensing area across its 16.5˝ length and width. Paired with
Dwyer’s universal handheld and UHH gateway, live velocity readings are displayed
in the Mobile Meter Application. The readings can be stored and shared via email for
later reporting. Its lightweight design allows end users to hold the instrument for longer
periods of time without stress on body joints. The thicker pole allows a rmer grip which
promotes consistent readings. The 160GW comes standard with an extendable pole
offering a maximum reach of approximately 48˝. The ball pivot joint and tightening nut
allows the user to position the sensing grid at any angle in any direction for ease of use
in hard to reach locations. It can be stored in the separate UHH-C2 hard carrying case
with foam cut-outs perfectly sized for the 160GW, as well as various other instruments
in the AQTIAP Air Quality Test Instruments line.
Assembly
Attach the Stand-Offs
The 160GW comes with two sets of stand-offs (Parts A1 and A2 in Figure 1) that are
different heights and they can be connected to each other to form a third different
height. The stand-offs ensure the air ow grid is sitting perpendicular to the grill to get
the most accurate readings. Once the proper height stand-off is chosen, the bumpers
(Part B in Figure 1) should be attached to the stand-offs to prevent the 160GW from
scratching the surface around the grill. The stand-offs can be screwed into the top side
of the air ow grid.

Attach the Handle
One extendable pole is included to reach a maximum of 48˝. The pole (Part E in Figure
1) will slide into the bottom feature on the adapter (Part D2 in Figure 1) and afx to the
adapter with the push button pin (Part D3 in Figure 1). The adapter will then thread into
the female thread on the ball pivot joint (Part D1 in Figure 1). Next, the male thread
on the ball pivot joint will thread into the air ow grid on the opposite side of the stand-
offs. The plastic nut on the ball pivot will lock the air ow grid in place and prevent it
from spinning once it is tightened. Finally, the user can adjust the ball pivot to adjust
the angle at which the air ow grid is going to measure. In order to adjust the angle of
the air ow grid, the user will loosen the plastic wing nut located on the side of the ball
pivot and tighten at desired angle.
Connect Tubing
The tubing provided with the air ow grid is color coordinated to help identify which
tube is going to the high pressure port and which tube is going to the low pressure
ports on both the manometer and the air ow grid. The tubes are pre-connected during
manufacturing. In the event the tubes become disconnected, for return air grill, connect
the clear tube to the pressure port on the side of the ball pivot joint (high pressure) and
connect the blue tube to the pressure port on side of the stand-offs (low pressure). For
a supply air grill, the ports would be reversed.
MAINTENANCE/REPAIR
Upon nal installation of the Model 160GW, no routine maintenance is required. The
Model 160GW is not eld serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
WARRANTY/RETURN
Refer to “Terms and Conditions of Sales” in our catalog and on our website. Contact
customer service to receive a Return Goods Authorization number before shipping the
product back for repair. Be sure to include a brief description of the problem plus any
additional application notes.
