FAQ

Q1: Working principle of sludge sensor ❯

The sludge concentration sensor is designed based on the principle of light scattering measurement. When a light beam enters the water sample, suspended particles within the sample cause light scattering. By measuring the intensity of the backscattered light and comparing it with internal calibration values, the sludge concentration in the water sample is calculated. The final value is output after linearization processing.

Q2: What does a water quality sludge sensor primarily measure? ❯

Water quality sludge sensors are primarily used to measure sludge concentration or suspended solids content in water bodies. They are commonly employed in scenarios such as wastewater treatment, sedimentation tanks, return sludge, and sludge discharge control, helping to achieve stable process operation.

Q3: What application environments are suitable for water quality sludge sensors? ❯

The sludge sensors are suitable for municipal sewage, industrial wastewater, sludge thickening tanks, and biochemical treatment systems. They can operate stably over extended periods under specific temperature, pressure, and corrosive conditions.
