Continuous Acoustic Level Meter ADAU-1 for Automatic Water Level Measurement

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