High quality non contact liquid level sensor online shopping? The sensor of the High-Pro type liquid level controller couples the generated high-frequency ultrasonic pulse to the vessel wall through a couplant. The pulse propagates in the wall of the container and in the liquid. It will also be reflected by the inner surface of the container. By detecting and calculating the characteristics of the reflected signal. The measured data is transmitted to the on-site secondary meter through the 485 serial port in real time. It can be judged whether the liquid level reaches the position where the controller is installed.
The advantages of ultrasonic liquid level gauge are very outstanding. It is mainly reflected in the following aspects : Safe and clean. The instrument has long service life. The measurement is stable and reliable with high precision. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: There is a blind spot in the ultrasonic liquid level measurement. The dead zone is the area where the meter cannot measure. During the transmission of ultrasonic pulses, a small area near the ultrasonic transducer usually cannot receive sound waves. The blind zone where sound waves cannot be received is related to the measurement distance of ultrasonic waves. Generally speaking, the smaller the measurement distance, the smaller the blind zone. The larger the measurement distance, the larger the blind zone.
In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver. Through piezoelectric crystal or magnetostrictive device into electrical signals. The distance between the sensor and the measured liquid surface is calculated by the time between the transmission and reception of sound waves.

Infrared online debugging function : Applicable to occasions where it is not suitable to open the cover for testing in dangerous situations. At the same time, it reduces the difficulty of debugging. Self-diagnosis function : It has its own working status diagnosis function. It also has hardware diagnosis function. It enhances the reliability and stability of the level gauge. One-key recovery function : When the external measuring level gauge works abnormally, it can be restored to the normal state with one key through the debugger. Local display and remote transmission function : The level gauge can not only display the level value on the spot in time. But also remotely transmit it to the control room through the signal line.
Ultrasonic Level Switch is not affected by factors such as medium density, dielectric constant, conductivity, reflection coefficient, pressure, temperature, precipitation, etc. It is suitable for various liquid levels in the pharmaceutical, petroleum, chemical, electric power, food and other industries Engineering control. Ultrasonic Level Switch is the ideal choice for the detection of toxic, highly corrosive, and dangerous liquid level. Sino-Inst offers a variety of Radar Level Transmitters for level measurement.
