Capacitive Level Meters
Reliable capacitive level measurement solutions for hygienic tanks and process vessels, designed for continuous level monitoring in food, dairy, beverage and other sanitary process applications.
Capacitive Level Measurement for Process Tanks
Capacitive level instruments provide continuous monitoring of material level inside process tanks and vessels by detecting changes in electrical capacitance.
In hygienic processing plants, accurate and dependable level information supports process control, tank management, product handling and automation. The FMI51 configurations presented on this page are available with sanitary SMS and Tri-Clamp process connections.

How Capacitive Level Measurement Works
The measurement principle detects variations in electrical capacitance caused by changes in the material surrounding the sensing probe.
Sensing Probe
The probe extends into the vessel and forms part of the capacitive measuring system.
Capacitance Change
As the process material level changes, the electrical capacitance detected by the instrument changes.
Continuous Signal
The measured value is converted into a continuous output signal for monitoring and process control.
