Product Description: HG5 type glass tube liquid level gauge is a local type liquid level measurement, it is mainly used to directly indicate the height of the medium liquid level in various tanks, towers, tanks, boxes and other containers.

Instrument upper and lower valves are equipped with PN1.6MPa, DN20 flange, through the flange on the container, and the container to form a communication device, through the glass tube can be directly read the height of the medium liquid level in the container. The instrument is equipped with a needle valve at both ends, and the needle valve is equipped with a steel ball. When the glass is broken due to an accident, the steel ball automatically closes the needle valve channel under the action of the pressure of the container to prevent the outflow of the medium in the container.
