The Model 1030F is a microprocessor based flow rate indicator/totalizer with a 4-20 mA output that is proportional to flow rate and RS-485 communications. Flow rate and total can be displayed simultaneously on the 16-character display. The Model 1030F has five control inputs, which when switched to ground, perform specific functions such as resetting the totalizer. Four open collector control outputs may be used to interface with remote devices such as relays, counters, and lights.
