The LDUS1000W series ultrasonic sludge concentration meter/slurry concentration meter is an online monitoring instrument designed for measuring the concentration of high concentration sludge and slurry in municipal wastewater, industrial wastewater, industrial slurry and other treatment processes. Real time online monitoring of changes in sludge and suspended solids concentration ranging from 0.2% to 60% and automatic control of related process can be achieved. Ultrasonic measurement has absolute safety compared to X-ray measurement, and is therefore widely used in the field of water treatment.
