The probe coefficient entered into the MicroTrans
EQ
is based on the following equation:
∆
Where:
= Velocity (afpm)
= Non-amplified Pitot-tube Coefficient, 1096.70
∆
= Differential Pressure Measured by the Pitot-tube (in. w.c.)
= Actual Density (lb/ft

9.8.2. Piezometer Ring Coefficient
The Piezometer Ring Coefficient Menu allows a user to enter the correction coefficient associated with
the piezometer ring or amplified differential pressure flow sensor. Correction coefficients should be
obtained from the sensor or air handling unit manufacturer.
