The ultrasonic liquid level gauge serves customers through its safety, cleanliness, precision, long service life, stability and reliability, convenient installation and maintenance. It is applicable throughout various fields such as acid, alkali, salt, anti-corrosion, high temperature, etc.

During measurement, an ultrasonic pulse is emitted by the sensor (transducer). The acoustic wave is then received by the same sensor or ultrasonic receiver after being reflected by the liquid surface. Once the wave has been received, the device converts it into an electrical signal by piezoelectric crystal or magnetostrictive device. The distance from the sensor to the measured liquid surface is calculated based on the time between the transmission and reception of the acoustic wave. 

The ultrasonic liquid level gauge consists of three parts, the ultrasonic transducer, processing unit and output unit.

Level gauge measurement range: 0-40m, various forms are available, including systems for various corrosive and chemical occasions, high precision, remote signal output, and PLC system monitoring.

The level gauge can be connected to the display meter or various DCS systems through 4-20mA or RS485 (Modbus protocol or other customized protocol) to provide real-time liquid level data for industrial automation operations.
