MSL600
Installation, Operation & Maintenance Manual
IP262/Z0, Rev. AB
February 2012
8. Technical reference
8.1 Transmit pulse and echo processing
The transducer and it’s transmit and receive circuitry is optimized to work at 1.0MHz.
Some sludge blankets are indistinct.
The algorithm has been optimised to average out and ignore unwanted signals produced by particles in the
supernatant, whilst detecting and measuring the wanted signals from the sludge blanket.
Although the algorithm is designed to largely ignore particles in the supernatant, the information (size and
distance) is retained allowing a warning of this condition to be indicated.
9. Maintenance
The MSL600 should require no maintenance. It has no user serviceable parts inside.
Although the MSL603 transducer should keep its front face clean by self-cleaning the transducer should be
inspected periodically to ensure that algae or floating debris is not collecting on its side or transducer face.
