Ultrasound is a category of sound waves. The sound wave refers to the frequency range of a wave that the ear can feel between 20HZ~20kHz. Ultrasound is a sound wave with a frequency higher than 20000 Hz. It has good directionality, strong penetrating ability, and is easy to obtain concentrated sound energy. It spreads far in the water. It can be used for distance measurement, speed measurement, cleaning and welding. The ultrasonic level gauge is a non-contact level measuring instrument. It can be used to measure the level and flow of various containers or pipelines. It can also be used for sea water measured in drainage, reservoirs, rivers and lakes. Occupy an important role in the water level monitoring system.
When ultrasonic waves propagate, they have strong directivity and energy is easy to concentrate. Ultrasonic waves can propagate in a variety of different media, and can propagate far enough. The interaction between ultrasound and sound transmission medium is moderate. It is easy to carry information about the state of the sound transmission medium. Diagnosis ultrasound can be effectively transmitted in gas, liquid, solid, solid melt and other media.
The use of ultrasonic level gauge
The integrated ultrasonic level gauge is a distance measuring instrument developed through the use of ultrasonic principles. Use the transmitted sound wave pulse to measure the time at the receiving end to calculate the distance. The ultrasonic level gauge is made of ABS material, which is light in weight. No maintenance and on-site calibration are required. It can be used in conjunction with a computer, data collector or other RS485-compliant collection equipment. The Jingxun Changtong ultrasonic level gauge device is small. But the function is complete, a variety of practical functions are integrated in one. It can detect sewage level, tank water level, solid level, river pond, lake water level, acid-base measurement, etc. Solve various difficulties. Ultrasonic level gauges are widely used in industrial water tanks, tanks, municipal engineering, water conservancy and hydropower, sewage treatment, petrochemical and other industries to measure the distance of the liquid level.
