Description

Liquid level switch ultrasonic with a ring sensing element. It is installed on the tank to control the level at a predetermined point. Due to the removal of the electronic part of the signalling device beyond the working area to the body, and therefore beyond high (low) temperatures, by means of a waveguide, it is possible to work with media at extreme temperatures. Adjustment to a specific temperature is made by decreasing or increasing the height of the signalling device stand.
The instrument 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 a modification with a sensitive element made of 10X17H13M2T steel, it is possible to work with a wide range of chemically aggressive substances.
Due to the specificity of the CE, it has high mechanical strength, as well as easy to clean from contaminants (if necessary)..
