Requirements for using glass tube level gauges in solvent storage tanks.
Thread Content
In recent new projects, regarding the level gauges for organic solvent storage tanks, the design team has stated that glass tube level gauges cannot be used. Could anyone in this group tell me which standard requires this? Is it mandatory? Is it necessary?
It’s better not to use it, as it’s prone to collision and breaking.

The HG5-227-80 type glass tube level gauge is primarily used to directly display the liquid level height in various containers such as tanks, towers, vats, and boxes. The gauge is equipped with M27×1.5 or ZG3/4\" threaded connectors on both the upper and lower valves; it connects to the container via flanges to form a communicating vessel, allowing the liquid level inside the container to be read directly through the glass panel. Both the upper and lower valves are equipped with steel balls; when the glass plate is damaged due to an accident, the steel balls block the passage under the pressure inside the container, thereby automatically sealing it and preventing the liquid inside from continuing to flow out. There is a plug hole screw at the valve end of the gauge, which can be used for sampling or to drain the remaining liquid from the gauge during maintenance.
There are rules; it’s not allowed to use it! Forced.
Level gauges made of glass tubes are rarely used in the chemical industry; they must not be used at all with hazardous substances. The reason is that such gauges can easily break due to collisions, leading to leaks, and substances with high viscosity can cause the entire gauge to take on the color of that substance, making it difficult to observe the liquid level. It is recommended to use magnetic flap level gauges. Since this is a new project, it’s important to get everything right from the start, and safety inspections provide an opportunity to raise such issues. Therefore, it’s best to follow the design specifications.

Which standard requires this?
