The Echotel® Model 355 is a two-wire loop-powered ultrasonic non-compact from Magnetrol that measures liquid level, volume, or open channel flow. It is offered with HART® communications with a PACTware™ PC to allow remote configuration and trouble shooting.

This device releases ultrasonic pules from the transducer. It then measures the time required for the echo to reflect from the liquid surface and go back to the transducer. It is commonly used for chemical storage tanks, level monitoring of ponds and rivers, and many more.
