GV
D-30-5
Air flow sensor for VAV-system
1999.12
The GV sensor is intended for direct in-duct installation
primarily in VAV boxes. It measures the air velocity
across the cross-section of the duct. An output signal is
then transferred to the measurement chamber in the
VAV controllers TAC 224V and TAC 224VL.
– Measures the mean value of the air velocity across
the cross-section of the duct, which produces a very
high accuracy of measurement.

The total length of tubing between the GV and the air flow
controller should not exceed 1,5 m.
– Impurities normally present in the duct, have accu-
racy of measurement.
– The GV can be used in all types of ducts, in existing
as well as new VAV installations.
– Designed of two parts, a bracket and a tube, for sim-
plified installation without special tools.
– It can be delivered for a large number of duct dimen-
sions.
