Description
Liquid level switch ultrasonic with a ring sensing element. It is installed on containers to control the level at predetermined points. The device design allows to detect 2 points of medium control. Due to removal of the electronic part of the signalling device outside the working zone to the body, and, consequently, outside the high (low) temperature limits, by means of a waveguide, it is possible to work with media at extreme temperatures.
The device is designed for operation in vessels with simple media, for control of oil products, gas condensates, and various media with density from 450 kg/m3. When using modification with a sensitive element made of 10X17H13M2T steel, it is possible to work with a wide range of chemically aggressive substances. The CE has high mechanical strength, and also can be easily cleaned from contaminants (if necessary)..
