Sludge Concentration Inline Measurement
suspended solid measurement in pipeline (Sludge Concentration) in sewage. up to 7%


I am looking for the best way to measure the concentration of sludge in sewage treatment in flow up to 7% SS (70000 mg/l). I know IR sensor been used but for up to 5% SS, ultrasonic also used. however, I am looking for low cost sensor.

please if you have any suggestion or any one expert in this field guide me with best option. I am thinking of buying ultrasonic probe from Amazon then I use LabVIEW as data acquisition and process the signal or do you think its not worth to try.

Thank you very much and I am looking for your reply.

Most important is what kind of sludge, not just concentration.
Primary, Waste Activated, chemical sludge, digested sludge....

Please advise.


thank you for your reply. It's primary sludge. It's feed to drum thickener from big sewage tanks.

Thank you
