EchoSwitch,Multi-Point,Ultrasonic Level Switch,Flowline

EchoSwitch Multi-Point Ultrasonic Level Switch From Flowline
Application
The general purpose ultrasonic switch provides non-contact level detection up to 26' or 8m with 3 relays. Each relay can be configured on a single set point alarm, automatic fill or empty including pump alternation or duplexing control, or two set points for out of bounds alarms. The switch is well suited for a broad range of corrosive, waste and slurry media, and is broadly selected for atmospheric day tank, process vessel, pump lift station and waste sump applications.
