Therefore, an input frequency of 650.00 Hz represents a flow rate of 3446.4 kg/hr in this
application.
For a given input frequency, you may also determine the current output. Use the prior example
with an input frequency of 275 Hz:
URV= 3600 kg/hr
= 10.48 mA
Therefore, an input frequency of 275.00 Hz represents an output current of 10.48 mA.
