1) Operating frequency. The working frequency is the resonance frequency of the piezoelectric wafer. When the frequency of the AC voltage applied to its two ends is equal to the resonance frequency of the chip, the output energy is the highest and the sensitivity is the highest. (2) Working temperature.

Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high frequency (20 kHz to 200 kHz) acoustic waves that are reflected back to and detected by the emitting transducer.

The ultrasonic flow meter works on the principle that it uses sound waves to resolve the velocity of the liquid in the pipe. There are two cases of no flow and flow in the pipe. In the first case, the frequency of the ultrasonic waves is transmitted into the pipe and the indication from the fluid is similar. In the second case, the frequency of
