External level transducer is an instrument which adopts sonar ranging and micro vibration analysis technology to measure the liquid level from the outside of the container. There is no need to opening holes on the tank wall, as well as the flange, it doesn contact the gas and the liquid in the tank. It is a completely non-contact instrument to realize the online installation and maintenance.
MR-ELL- SA External level switch is a non-contact level switch by using the Variable frequency ultrasonic technology, it is widely applied to all kinds of liquid level detection. The measuring probe is installed on the external wall of the container. And it belongs to a completely non-contact instrument which measure the level from outside of tank.
