Best ultrasonic level switch online store? 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 : The structure is simple. The reading is convenient. It is very easy to install and maintain. 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.
Ultrasonic Level Sensing measures liquid levels based on the principle of ultrasound. When ultrasonic waves encounter a high-density medium while propagating in a low-density medium, they cannot penetrate the high-density medium. There will be reflections at the interface of the two media. The ultrasonic liquid level gauge is made using this feature. Read even more info at Ultrasonic level switch.
For spherical tanks equipped with a calibrator. The calibration sensor is installed at the center of the calibrator on the outer wall of the tank. If the calibrator is not installed, the calibration sensor should be installed at the height of the outer radius of the tank (equatorial zone). The calibration sensors for the vertical tank and the process tank are installed on the outer side of the tank body, at a height of 0.5m to 1m from the tank bottom. Note: After installing the calibration tube (calibrator) in the tank, the correct installation position should be marked with paint on the outside of the tank wall in time.
What is ultrasonic level sensor? Ultrasonic level sensor is a monitoring instrument for measuring liquid height, tank height, and material position. The ultrasonic level sensor can adopt two-wire, three-wire or four-wire technology. The two-wire system is: power supply and signal output are shared. The three-wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24v power supply, a 3-core cable can be used, and the negative terminal of the power supply and the negative terminal of the signal output share a core wire. The four-wire system is: when using AC 220v power supply, or when using DC 24v power supply. When the power supply loop and the signal output loop are required to be completely isolated. A 4-core cable should be used. Read additional information at https://www.drurylandetheatre.com/.
