Meter Mounted Flow Monitor, RT-Ex3

The RT-Ex3 is a meter-mounted digital flow monitor housed in a Class I Hazardous Location Rated Enclosure. A large, back-lighted LCD graphic display provides easy to read indication of flow rate or total in user programmable engineering units. Change of display modes or reset of the totalizer is accomplished using an attached magnet without opening the enclosure. An isolated input also allows for remote reset of the totalizer. Programmable opto-isolated open-collector outputs provide flowrate limit indication or a pulsed total output for remote monitoring and recording of totals. A 4-20 mA rate output with user programmable filtering and scaling is also provided for remote rate indication and 24 VDC power is required. The RT-EX3 is compatible with all AW Company JVM and JV-KL Series flow meters.
