3.3 Calculation of Rate and Total
3.3.1 Frequency Input
The flowrate, R, is calculated as follows:
where f is the input frequency in Hz.
H is the timebase of rate and is 1 for seconds, 60 for
minutes,3600 for hours, and 86,400 for days.
S is the Scaling Factor.
The Scaling Factor, S, is equal to the K-factor of the flowmeter
expressed in pulses per unit volume.
The user sets the Scaling Factor and selects the timebase during the
configuration process as detailed in Section 5 of this manual.
