Contrasts between ultrasonic, radar level gauge and sonar level gauge
Ultrasonic level meter is well known as a carrier ultrasonic, radar level gauge is based on the electromagnetic wave as a carrier. Whether ultrasonic or electromagnetic waves are easily absorbed by the water, because water is a polar molecule, so ultrasonic or radar level measurement in liquids error signal loss is large, and the sonar is different, a few kilograms of bomb explosions in the deep sea , twenty thousand kilometers away, you can also receive signals, the low-frequency sound waves can also penetrate several kilometers of undersea formations, formations and get information. In water measurement and observation, it has yet to find more effective means than sound waves. Shaanxi sound Electronics Co., Ltd. After several years of painstaking research, to overcome technical barriers, and finally succeeded in developing the use of sonar principle to measure various types of tanks posted outside the precise level of the level gauge, the gauge break tradition Installation cans contacts to achieve a level of true non-contact measurement of the height of a closed container. Sonar transducer (probe) is mounted on the outer wall just below the test container (bottom), without opening the container to be measured, easy to install, installation can be achieved online. Available for high temperatures, toxic substances ﹑ ﹑ alkali and various acids pure liquid level high pressure airtight container for accurate measurement. Level meter for liquid media and container materials, no special requirements, and the use of explosion-proof design to meet explosion-proof requirements, can be widely used.
