 New DFM-IV Doppler Flow Meter

DFM-IV Doppler Flow Meter

Use the isolated 4-20mA to transmit flow to remote displays, recorders or controllers. The 3 programmable relays can be used for flow control, pump protection or flow proportionate pulse. Calibration is easy with the built-in 3-key calibrator. Display and totalize flow in your choice of engineering units (gallons, liters etc.)

Sensor cable can be extended up to 500 ft. (152 m) with no loss of signal. The DFM-IV can be equipped with intrinsic safety barriers for sensor installation in hazardous rated locations. Other options include high temperature sensors, dual-head sensors and a built-in.
