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.
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.
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.
