Sludge Level Measurement

Sludge Level Detection for clarifiers and thickeners.

Measuring sludge blankets in clarifiers or thickeners is challenging, but the EchoSmart has proved to be very reliable in South African applications.

The Smart sensor is mounted under water and an ultrasonic beam continuous sludge level measurements. The optional self-cleaning wiper removes bubbles, slime and other material accumulations from the sensor to provide reliable operation in hostile environments.

EchoSmart is an underwater interface level analyser technology that is built on a digital platform. This allows the analyser to be located in the sensor. The result is greater flexibility in equipment configuration options, enhanced communication capabilities and reduced installation costs. EchoSmart’s unique Smart-Sensor technology enables the control and monitoring of up to 16 Smart Sensors from one EchoSmart Controller. This allows for field networks of sensors, which lowers the ‘per-tank’ cost. These field networks can also be created wirelessly, eliminating costly conduit and cabling runs.

EchoSmart is adaptable and can be programmed to suit various tank sizes and designs. Three sensor models provide a solution for most applications: the standard sensor with multi-flex assembly for when surface skimmers are present, the self-cleaning sensor for applications without surface skimmers, and the sensor with turbidity that offers further insight into water clarity.


  • Sensors generate and process the ultrasonic signal for continuous, real-time measurement and maximum flexibility.
  • Easy to set-up, easy to operate and easy to secure consistent, reliable, trouble-free measurements
  • Tracks well-settled blankets
  • Can be configured to track dispersed solids (fluff or rag layer)
  • Suitable for round or rectangular clarifiers
  • Standard sensor for applications with surface skimmers. Multi-flex assembly recommended.
  • Wiper sensor: self-cleaning face for applications without surface skimmers.
  • Level & Turbidity sensor: self-cleaning face with sludge level and turbidity in one sensor
