3.3 CALCULATION OF RATE AND TOTAL

3.3.1 Frequency Input

The flowrate, R, is calculated as follows:

R = f x H

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 programs the Scaling Factor and selects the timebase during the

Calibration procedure as detailed in Section 5 of this manual.
