MSL600 Sludge Blanket Level Monitor

Supplier: Measurement Plus

The MSL600 sludge blanket monitor is a microprocessor based system, with an abundant range of built-in, display, control and alarm features.

Price Guide: POA

Easy to use menu driven programming allows complete configuration of the unit. Local programming is carried out via a membrane keyboard.

The MSL600 uses the sonar principle, with an ultrasonic pulse transmitted under water. Sophisticated echo processing allows the MSL600 to analyse the pulse of ultrasound which transmits vertically and reflects from the surface of the sludge blanket. The system captures the ultrasonic echoes reflected from the blanket interface.

Knowing the speed of sound in the supernatant, the depth of the sludge blanket is then determined from the time of flight of the echo.

The system comprises an ultrasonic transducer and a bridge mounted control unit. These are specially designed for easy installation on a clarifier tank bridge using a mounting bracket, supplied with the system.

The control unit includes an integral air compressor which provides the air blasts across the transducer face to prevent build up of deposits or algae.
