A loop powered (4-20mA DC) two wire indicator displays 4 1/2 digits for flow rate and 8 digits for totalization. Includes scaled, open collector output for remote totalizer. Numeric password protection prevents unauthorized access to menu. The easy to read menu prompts make the RW3 so easy to program. An isolated scaled pulse output is available for hook up to a remote totalizer.

A solid state strain gauge senses the differential pressure directly which provides a 4-20mA signal Output is proportional to flow rate squared. Square root extraction is required in the receiving device, the digital display requires a 24Vdc power supply can be purchased separately (PS-24 Power Supply) .
