Оperating principle


The principle of operation Level sensor is based on measuring the propagation time of ultrasonic waves from the bottom of the tank to the liquid surface.

Purpose:

Non-contact ultrasonic level sensors LL-b are designed to measure the level of liquids, such as fuel, water, milk, oil, coolant, acids, etc. without contact with the measured medium in the various control systems and automatic control.
Allows control of pressure vessels, as well as in cases where the damage to the tank is not allowed for reasons of explosion safety or sanitation.
