The Blancett Frequency-to-Current (F-to-I) and Frequency-to-Voltage (F-to-V) converters are microprocessor-based devices designed to provide an analog output directly from a Blancett turbine flow meter. The converters measure and calculate the flow rate of a turbine flow meter and produce an analog output representative of that flow rate, in the form of a 4-20 mA or 0-5 VDC signal.
