The Blancett K-Factor Scaler converts a low level frequency output (such as the output from a Blancett turbine flow meter) into a scaled square wave output signal. This adjustable frequency divider converts or "scales" the turbine meter output into units of measurement needed for a particular application and recognized by almost any data collection device. The k-factor scaler provides an amplified signal, even when a frequency conversion is not required. This signal is more immune to electrical noise and capable of transmission over longer distances than a raw turbine meter output.

What is a k-factor? Every turbine flow meter has a unique k-factor, or ratio of pulses per unit of flow. As the turbine rotates within the flow meter, each time a turbine blade passes the face of the magnet an electronic pulse is created. The total number of pulses corresponding to one unit of flow is the k-factor. For a Blancett turbine meter, the k-factor is the number of pulses equivalent to 1 gallon, and every flow meter is labeled with its unique k-factor. Because this k-factor initially applies only to gallons, the B220 k-factor scaler is a low-cost and convenient way to convert the turbine output into a different frequency, representing a different unit of measure.
