Level transmitters

Level transmitters

Level transmitters measure the level of liquids in tanks, pipelines, as well as in natural waters such as rivers, lakes, and reservoirs. They enable precise monitoring and control of liquid levels.

Wika and Magnetrol level transmitters operate based on different principles, including ultrasonic, pressure sensor, or conductivity methods. They help prevent overfilling or excessive level drops.

They can operate across wide temperature and pressure ranges, and are also available in explosion-proof versions.
