LEVEL - SLUDGE
Sludge Level Detection and Control for use in clarifiers and thickeners with optional turbidity probe.
Measuring sludge blankets in clarifiers or thickeners is difficult, but the EcoSmart has proved to be very reliable in South African applications. The smart sensor is mounted under water and an ultrasonic beam gives 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.
Number of sensors can be interlinked into one controller providing low-cost multi-point measurement. The EcoSmart has a maximum measuring range of 10m and a typical resolution and accuracy of 3mm at mid-range. The EcoSmart is easy to setup with its intuitive menus and the output is available as 4-20mA, RS485 or modbus protocol.
