The level gauges are designed for continuous automatic remote measurement of the level of non-boiling distilled water and high purity water in hermetically sealed tanks. The level transmitters have two measurement channels - analogue and discrete, working in concert.
The principle of operation of the analogue channel is based on the property of ultrasonic oscillations with different acoustic resistances reflected from the interface. The principle of action of the discrete channel is based on the change in the energy of ultrasonic vibrations passing through a liquid or gas, due to different values of acoustic impedances of these media.
