DR-1
Remote Digital Display
Remote digital displays with 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 DR-1 so easy to program. An isolated scaled pulse output is available for hook up to a remote totalizer.
This remote digital display can be used with our 4-wire transmitter linear signal (Option W) as well as our 2-wire transmitter square root signal (Option W2, and W3) both provide 4-20mA signal Output which is proportional to flow rate, the digital display requires a 24Vdc power supply which can be purchased separately (PS-24 Power Supply) . The W2 and W3 requires a square root extraction at the receiving end.
