Integrated ultrasonic level gauge
liquid
Gas, solid
Ultrasound wave is a sound wave with a frequency higher than 20KHZ, which has good directivity and penetration, and is easy to obtain concentrated sound energy. Spread in air, liquids, and dense solids. The liquid level detection instrument developed by using its characteristics combined with modern microcomputer technology is called an ultrasonic liquid level gauge.
The ultrasonic level gauge is to install the ultrasonic transducer above the measured object. The ultrasonic transducer emits sound wave signals and simultaneously receives the sound wave signals reflected by the measured object. By measuring the time difference between transmission and reception, the measurement distance is calculated according to the propagation speed of sound waves in the air.
