Dwyer Series FIV Analog Input Flow Indicator

Flow Rate and Totalization

The FIV Series are flow rate/totalizer/batch controllers ideal for almost any flow application involving an analog signal. They display both flow rate and total on an easy to read 7 segment LED display that provides up to 4-1/2 digits of rate display and 6 digits of total display. The analog input meters accept all the standard process signals. The meters also provide a loop power supply to drive the sensor.

For applications requiring more than just a display of rate or total, these meters can be equipped with two relays and a 4-20 mA retransmission output. The relays can be used for alarming based on the flow rate or for simple batch controlling based on the flow total.

The relays can also be used for applications beyond flow. For instance, they can be programmed for alternation making these products ideal for pump-control applications.
