Non-Invasive Sonar Ultrasonic Level Meter/flow meter

Non-Invasive Sonar Ultrasonic Level Meter

The intelligent Non-invasive Sonar ultrasonic level meter (hereinafter referred to as the externally attached liquid level meter) adopts advanced signal processing technology and high-speed signal processing chip, breaks through the influence of the wall thickness of the container and realizes the non-contact measurement of the liquid level in the closed container. The sonar ultrasonic probe is installed at the closed container’s bottom, no need to open holes on the container, the installation is simple, not affect the production. It can accurately measure liquid level of various toxic substances, strong acids, strong alkalis and various pure liquids in the high-pressure airtight containers. This kind liquid level meter adopts explosion-proof design and widely service high pressure, radioactivity, toxicity, corrosion and other special occasions.
