Ultrasonic level sensor

for sludgeanalogfor basin

The SLD1100 mud layer interface meter includes a host, rotary table structure, cables, detection probes and cleaning systems, etc., installed at the top of the settling tank. The cables are wrapped around the rotary table structure as a whole and one end of the cable is connected to the detection probe. The host controls the rotation of the rotary table structure to input/lift the cables, thereby controlling the position of the detection probe inside the settling tank. The detection probe uses an ultrasonic probe to emit ultrasonic signals at different positions in the settlement tank. Due to the different densities of the media in each layer of the settlement tank, the effect of the emitted ultrasonic signals will also be different. The host analyzes the differences in the echo signals received by the ultrasonic probe at different positions to determine the positions of the interface between each layer. In addition, there is a cleaning system installed on the top of the settling tank, which cleans the detection probe every time one or several detection cycles are completed to avoid scarring and affect measurement accuracy.
