Therefore, an input frequency of 80.00 Hz represents a flow rate of 1694.6 lpm in this
application.
For a given input frequency, you may also determine the current output. Use the above
example with an input frequency of 80.00 Hz:
URV= 2000 lpm
= 17.49 mA
Therefore, an input frequency of 80.00 Hz represents a current output of 17.49 mA.
