DESCRIPTION : 

Ultrasonic Level Meter is cost effective liquid level measurement technology. Ultrasonic Level Sensing sensors and transmitters are used

for tank or river level measurement. Ultrasonic Level Sensing does not need to contact the medium, can be continuously measured, low cost. 

Therefore, Ultrasonic Level Sensing is very popular among users. Ultrasonic liquid level sensors are available in general and intrinsically safe types. 

Output 4~20mA standard signal or output the measurement result to the secondary meter through RS-485. Meets the system’s automatic control.

PRINCIPLE : 

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.

In the measurement, the ultrasonic pulse is emitted by the sensor , and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver. Distance between the sensor and the measured liquid surface is calculated by the time between the transmission and reception of sound waves.

Due to the non-contact measurement, the measured medium is almost unlimited. It can be widely used to measure the height of various liquid.
The ultrasonic liquid level transmitter is composed of three parts: ultrasonic transducer, processing unit and output unit.The Ultrasonic level meter is instrument of measured material level,which is non-contact, high reliability, cost-effective, easy to install and maintain. It meets the requirements of material level without the contact.
