Turbine flow meters have a unique k-factor, or ratio of input pulses per unit of flow. For a turbine meter from Blancett Flow Meters, the k-factor scaler is the number of pulses equivalent to 1 gallon. Because this k-factor applies only to gallons, it is said to be a low-cost and convenient way to convert the turbine output into a different unit of measure. The k-factor scaler converts a low level frequency output into a scaled square wave output signal.
