Sludge level detection, immersion depth up to 10 m, in primary and secondary clarifier, thickener, rotten black sludge, sludge level measuring in small sewage plants
Adjustable threshold of turbidity detection
Accumulator battery operated Range of 100 measurement cycles of 7 minutes each Automatic switched off after 7 minutes Charging time of 2 h 30 min as a maximum
DESCRIPTION
A turbidity sensor (emitter plus receiver) is mounted on an immersion probe with an integrated hydrostatic level sensor.
The light beam is in Infra red range at 940 nm.
OPERATION
When the immersion probe reaches the sludge surface, the device switches on an audible alarm and a lightning alarm.
At the same time the depth of immersion is displayed on the main housing.
