Section 5 - Calibration

The HM flowmeter signal probe detects motion from the rotor to provide a pulsed output. Due to slight

changes in meter dimensions, the volume of liquid displaced by the rotor is not the same for every flowmeter.

To account for these changes, each meter is flow tested at the factory. A specific numeric value is determined.

This identifies the amount of pulses the meter will output per a fixed volume that passes through it. In the case

of Anderson flow products a gallon is the volume. This value is labeled on the meter body as a "P/G" pulses

per gallon, which is also know as a "K-Factor". Pulsed output values are normally entered into digital converter

as a divider value "K-Factor", or as a multiplier value known as a "Scale Factor". Either method converts the

unscaled pulses of a flowmeter into the desired engineering unit of your choice, such as gallons, tenths of

gallons, liters, etc.
