Ultrasonic level meters LEVELIS LU-55

levelis_novyThe LEVELIS LU-55 ultrasonic level meter is used to continuously monitor the level height of liquid media, sludge or suspensions in both open and closed tanks and channels. The level gauges of the LU-55 series require two-wire connections to the associated electronic devices. The gauge generates the level-height 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.
