Sludge Level Detection and Control in clarifiers and thickeners.
Measuring the sludge blanket level in clarifiers or thickeners is challenging, but the EcoSmart has proved to be very reliable in South African applications. The smart sludge level 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 level measurement even in hostile environments. An optional turbidity probe is available.
A number of sensors can be interlinked into one controller providing low-cost multi-point sludge level measurements. The EcoSmart has a maximum measuring range of 10m with resolution and accuracy of 3mm at mid-range. The EcoSmart is easy to set up with its intuitive menus and the output is available as 4-20mA, RS485, or modbus protocols.
