Ultrasonic level regulators UZR-1 (-1I)

The ultrasonic level controller UZR-1 (- 1I) is designed for monitoring and regulating the level of non-boiling media in apparatuses and vessels of stationary and ship installations.

Ultrasonic level regulators UZR-1 (- 1I) meet the requirements of the Rules of the Russian Maritime Register of Shipping and the Russian River Register, are designed for use at nuclear power facilities.

The principle of operation is based on the use of the method of pulse ultrasound sensing with time and frequency selection, which consists in comparing the time of passage of the ultrasonic signal through the working gap of the sensor element of the primary converter, filled with a controlled liquid or gas, with the time interval generated in the controller itself.
