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....
