Abstract
A liquid flow sensor produces output signals which are monitored over a known volume of flowing liquid. That monitored signal value is scaled according to a predetermined volume of liquid to provide a correction factor, whereby the output signal of the flow sensor is continually corrected to provide an expected number of flow sensor pulses per unit volume.
