Flow Measurement
Sensor Type Integral Orifice sensor
Sensor Accuracy Sensor error < 2% of signal.
Total Flow measurement error <
±5% above 350 fpm duct
velocity.
Installation
Requirements
No special inlet or outlet
conditions required to maintain
pressure independence.
For best airflow measurement
results, provide at the inlet at
least one equivalent diameter of
straight duct, or a transition with
less than 30 degree taper.
Support adjoining ducts within
12” of the air valve.
