Top non contact liquid level sensor 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 : 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: Ultrasonic liquid level gauge is greatly affected by dust. This is because although the dust environment has little effect on the speed of sound, it has a very significant effect on the attenuation of sound waves. Therefore, it is best not to use an ultrasonic level gauge in the presence of dust.
Due to the non-contact measurement, the measured medium is almost unlimited. It can be widely used to measure the height of various liquid and solid materials. The ultrasonic liquid level transmitter is composed of three parts: ultrasonic transducer, processing unit and output unit. Read even more information on non contact liquid level sensor.
The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank. The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.
Ultrasonic level switch is installed outside the tank. No need to open holes in the tank. Non-Contact Measure. The ideal choice for tank level monitoring. Ultrasonic Level Switch, External Mounted (referred to as “external level switch”) is a new type of level measurement alarm device. Ultrasonic Level Switch is mainly used to detect the liquid level of the storage tank. It can realize the upper and lower limit alarm or monitor whether there is liquid in the pipeline (dry protection). The material of the storage tank can be various metals, non-metals or non-foamed plastics. The wall thickness can be Up to 70mm. See extra info on here.
