Application of Ultrasonic level meters

The ultrasonic level meter is used to continuously monitor level channels in the height of liquid media, sludge or suspensions in both open and closed tanks and channels. The gauge generates the levelheight information in the form of a signal current 4 to 20mA. The lower and upper limits of the measurement range can be set by potentiometers in the electronic unit of the gauge.
