The ultrasonic sensor emits a beam of ultrasonic immersion ultrasonic in the process toward the bottom, downward propagation, encounter suspension, sedimentation of sludge will be reflected back, and different density of the sludge layer reflected signal intensity is also different. By measuring the intensity and time of the ultrasonic signal reflected by the instrument, the depth and thickness of the sludge interface can be obtained after treatment.

● Reliable ultrasonic echo measurement principle, easy to use;
● Optional automatic cleaning system, reduce maintenance workload, improve work reliability;
● The ultrasonic energy can be adjusted automatically, and it can adapt to various measuring media and wide range;
● Advanced circuit design and software algorithm can eliminate the interference on the spot, and the measurement results are stable and reliable;
● The large screen liquid crystal display measurement value can be displayed at the same time the sludge layer state;
● Chinese menu, easy to operate;
● 4~20mA isolated current output;
● Fault self-diagnosis function;
● Upper and lower alarm and fault alarm relay output
