ACCESSORY
Difference in the cone surface pressure and fan inlet pressure (∆p) canbe correlated to the volumetric air flow rate (Q) with which
fan is moving, using equattion shown below and can be analysed to read out the real time fan performance accurate to
To complete the installation of the transducer, follow the installation instructions located at 5%
Q = K * √(∆p)
Q = Volumetric flow rate (CFM)
∆p = Differential Pressure (inWC)
K = Fan constant, as noted in table:
