Note also that as the last two K-factors are the same any flow above 100 gpm will be modified by a K-factor of 104. In simple terms, these higher-order fits give instructions on how best to predict an output given a measured input. Dividing the total number of pulses generated by the specific amount of liquid product that passed through the PTF determines the K-Factor. In vortex flowmeter, the relationship between flow rate and the number of vortexes generatedcan be expressed by the following formula.
