Description

Memosens CUS71E is an ultrasonic sensor for monitoring sediments in basins, tanks, and reservoirs. Precise identification of the interface level between water and sediments enables reliable process control. Manual measurements are no longer required, system availability is increased, and the integrated sensor cleaning ensures consistent measurement results. The unique sedimentation factor serves as a quality indicator of the precipitation process and optimizes chemical dosing.

Field of application

Memosens CUS71E measures the interface layer between water and sediments to support the automation of sedimentation processes in the following applications:

  • Wastewater treatment
  • Drinking water treatment
  • Mining
  • Hydropower
