Level transmitters
Level Transmitters
Level transmitters measure the level of a given liquid in tanks, pipelines, or even in natural waters such as rivers, lakes, and reservoirs. They enable accurate monitoring and control of liquid levels.
Magnetrol level transmitters operate on different principles — for example, ultrasonic, pressure-based, or conductivity-based. They help prevent both overflow and low-level conditions.
They can operate across a wide range of temperatures and pressures, and explosion-proof versions are also available.
