Ultrasonic Level Gauges

An ultrasonic level gauge is an instrument that uses ultrasonic sensing technology to measure liquid levels. It consists of an ultrasonic transducer (probe), a driving circuit (module), an electronic liquid crystal display module, and other components. Its working principle is as follows: The transducer emits high - frequency pulsed sound waves. These sound waves are reflected when they encounter the surface of the measured liquid level, and then received by the transducer and converted into electrical signals. The liquid level height is calculated based on the relationship between the sound wave propagation time and distance. The calculation formula is: Distance (m) = Time × Sound Speed / 2 (m).

It has the following characteristics: Non - contact measurement, which means it will not contaminate or damage the liquid, making it suitable for corrosive or toxic liquids. It offers high measurement accuracy, reaching the millimeter level, ensuring the accuracy and stability of the measurement. It has a wide range of applications and can measure various liquids, including those with a high dielectric constant, bubbles, or particles. It has high reliability, being resistant to vibration and interference, and is suitable for industrial environments. It features flexible installation, without being restricted by the shape and material of the container.

This instrument can be applied in various fields, such as liquid - level monitoring in industrial production like the chemical, petroleum, and food - processing industries, environmental monitoring for sewage treatment and wastewater treatment, liquid - level control in water treatment facilities such as reservoirs and water towers, as well as liquid - level management in agricultural irrigation systems like reservoirs and ponds.
