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.

An ultrasonic sensor emits a sound pulse in the ultrasonic range. This sound pulse propagates at the speed of sound through air (about 344 meters per second) until the sound pulse encounters an object. The sound pulse bounces off the object and is returned in reverse to the sensor where this "echo" is received.

17/01/ · Ultrasonic Level Sensor Working Principle. January 17, . The working principle of this product is that the energy wave is transmitted through a device that can transmit an energy wave (generally a pulse signal). The energy wave is reflected by an obstacle and a reflected signal is received by a receiving device.

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

Advantages of using Flow Meter Clamp on ultrasonic:. There is no barrier on the flow trajectory, so there is no pressure drop. There are no moving parts, so no parts wear out that cause low maintenance costs. Multi sensor models have higher accuracy. It can be used to measure corrosive fluid flow and slurry.

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.

1) Physical principles. When fluid flows through a pipe, it flows in one direction at a velocity that is influenced by many factors, such as temperature, pressure, fluid viscosity, and pipe size. The higher the pressure differential upstream of a point in the pipe and downstream from that point, the higher the flow velocity.
