Ultrasonic Level Transmitter

Ultrasonic Level Transmitter is specifically designed for continuous non-contact liquid level measurement. The transducer (probe) sends out high frequency ultrasonic pulses. When a pulse hits the surface of measured liquid, it is partially reflected. The reflected wave is received by the transducer and converted into an electronic signal. The distance from the transducer to liquid surface is calculated according to the time difference between the pulse transmission and reception and velocity of sound wave. Because Ultrasonic Level Transmitter sensor is contactless, it can provide reliable continuous level measurements for applications in various open pools, for example, water pool in sewage treatment and other water resources in hydraulic and hydrological survey.


In Uson series of Ultrasonic Level Transmitter, microprocessor program control technology and intelligent signal processing technology are employed to provide highly efficient and accurate measurements. In comparison with other similar products in the market, Uson series of products has the following advantages:

 With three selectable measurement ranges, including 5 meters, 10 meters and 15 meters.

 Certified for high level explosion protection: EX d IIC T6 Gb.

 With temperature compensation function, offers high accuracy and strong adaptability.

 With RS-485 communication interface.

 Special echo signal processing algorism is used, can effectively avoid false echo signal.

 With IP66/IP67 ingress protection rating..

 Probe made of corrosion-resistant PVDF, suitable for corrosive liquids or applications under corrosive environment.

 High cost-effective ratio, low maintenance cost.


Uson series products have two models for applications under different operation conditions:

Uson-11 Standard Ultrasonic Level Transmitter:meets requirements of majority continuous level measurement applications for open pool or under corrosive environment.

Uson-21 Flameproof Enclosure Ultrasonic Level Transmitter:with flameproof enclosure design, suitable for continuous level measurement in open tank/pool where the atmosphere contains explosive gas and applications under corrosive environment.
