HG5-227-80 series glass tube level gaugeDetailed product description：

HG5-227-80 series glass tube level gauge features:

Direct reading, accurate reading, reliable
Simple structure and easy maintenance
Safe and durable to use
Instructions for Use:
To ensure self sealing, the pressure of the medium inside the container should be greater than 0.2 MPa. When opening the upper and lower valves, the number of rotations of the valve stem should not be less than 4 to prevent the steel ball from touching the top of the valve stem during self sealing.

Structural principle:
Both the upper and lower valves of the instrument are equipped with PN1.6MPa and DN20 flanges. By welding the flange on the container, a connector is formed with the container, and the height of the medium liquid level inside the container can be directly displayed through a glass tube. Both ends of the instrument are equipped with needle valves, which contain steel balls. When the glass tube ruptures due to an accident, the steel balls automatically close the needle valve channel under the pressure of the container to prevent the medium from flowing out of the container.
