Sludge Level Sensors Application:
Sludge level sensors and transmitters help you to pump sludge, not water. They continuously monitor the separation and transition zones of the clarification and settling phases, so that you can operate your process efficiently. Typical installations are at the primary and secondary clarifier of wastewater treatment plants to measure sludge level / sludge blanket level. Check out our sludge level sensor and transmitter portfolio for your sedimentation tanks by clicking on the button .
Ultrasonic sludge level sensors feature a piezoelectric crystal that is encased in a resistant polymer housing. When the crystal is excited with voltage it generates a sonar signal. In the process, ultrasonic waves are emitted to scan the separation zones. The measured variable is the time the emitted ultrasonic signal needs to reach the solid particles in the separation zone and return again to the receiver. The principle is well-proven and ensures a long-time stable sludge level measurement.
