Product details


product overview

The photoelectric sludge concentration meter is an online monitoring instrument designed to measure the concentration of suspended solids in municipal and industrial wastewater treatment processes. Can be applied to detect changes in activated sludge concentration during biochemical treatment processes, providing continuous and accurate measurement results. By adopting innovative multi beam mutual compensation technology, measurement errors caused by sensor window contamination can be eliminated, significantly improving measurement accuracy, reducing maintenance workload, and enhancing work reliability. It is particularly suitable for harsh working conditions in the field of sewage treatment.


working principle


The light waves emitted by the sensor transmitter are absorbed, reflected, and scattered by the measured object during transmission, and only a small portion of the light can reach the receiver. The transmittance of the transmitted light is proportional to the concentration of the suspended object being measured, and the concentration of the suspended object is calculated by measuring the transmittance of the transmitted light.
