Entering Calibration Constants

K-factors are supplied with flow sensor documentation, and need to be identified for the specific sensor
pipe size, converted to appropriate units if necessary, and entered for each channel. If a certificate of
calibration with multipoint linearization is provided (some vortex and turbine sensors) refer to the
instruction manual. Multiplier units entered into the M300 must be pulses per gallon, even if the readout
will be in other units. Enter Adder constants (if provided) in units of GPM.
If K factors are provided in units of GPM/Hz, divide 60 by the K value and enter the result as the
Multiplier, "M". For example, a K value of 2 GPM/Hz would result in a Multiplier of 60/2 = 30.
If an offset is provided in Hz, multiply it by the original K factor (in GPM/Hz) and enter the result as the
Adder, "A". If an offset is not provided, leave the Adder set to zero.
