Badger Meter Converters - Manual (Page 5)

INTRODUCTION
The Intelligent Frequency Converter is a state-of-the-art digital signal processing device designed to provide exceptional
accuracy at a very affordable price Designed for use with B220-954 turbine meters, the sensor measures and calculates the
flow rate to produce an analog current or voltage output representative of the meter’s flow rate
The Intelligent Frequency Converter is offered in two versions:
• The F to I converter provides a 4…20 mA output in a two wire, loop powered setup
• The F to V converter offers a 0…5V DC output for those applications where a voltage output is preferred
