Reliable sludge blanket measurement via optical sensor

• Optical measuring system for sedimentation profile measurement
• Continuous level measurement of sludge blanket (zone tracking)
• Common operating and service concept with other KROHNE devices

The sludge level meter OPTISYS SLM 2100 features an accurate and reliable profile measurement of the sedimentation tank using an optical sensor which travels through all layers of the tank reading suspended solids concentration at the different heights.

Highlights

• Direct measurement via sounding with an optical sensor
• 3 reliable measurement modes including determination of sedimentation profile, blanket and fluff levels as well as zone tracking
• Common operating and service concept with flow and level devices
• Build-in heater and ventilation for temperature regulation
• 2 x rake guard switch or trigger inputs
• 1 x maintenance switch
• 2 x programmable relays (status ouput or limit switch)
• Automatic cleaning unit for low maintenance efforts

Industry

• Waste water (industrial and municipal)
• Drinking water
• Power stations
• Mining

Applications

• Measurement of sludge blanket and fluff zone in primary and secondary clarifiers or sludge thickeners
• Monitoring of sedimentation processes
• Automation of sludge extraction
• Early warning of sludge washout
