Glass level gauges are used in storage tanks; does this type of gauge need to have indicators for the high and low limits? Are there any specific requirements? Please give me some advice, experts!
The high and low limit settings for level gauges are determined not by their type, structure, or material, but rather by the requirements of process safety. Awaiting professional guidance on the standard provisions
All level gauges need to be marked with high and low limits
Tanks that have liquid level indicators should be marked to facilitate on-site management and meet safety requirements. It is set by each company individually; there is no national standard. Additionally, glass tube level gauges seem to be becoming less and less useful
Okay, thank you. I would like to ask if it’s necessary to draw lines at the lower levels. After all, the jar can be empty
If you think it’s fine for the tank to be empty with no consequences, then you certainly don’t need to label it. Because it really makes no sense
In accordance with Article 12.5.2 of the \"Safety Technical Specifications for Vertical Cylindrical Welded Steel Storage Tanks\" (AQ 3053-2015), the level gauge should be installed in a location that facilitates observation; otherwise, additional auxiliary facilities must be provided. The highest and lowest safe liquid levels on the level gauge should be clearly marked.
Thank you for providing the correct analysis. The original poster did not describe this issue accurately, leading people to think it was just a tank that had nothing to do with other facilities. For example, the statement “it can be empty” gives the impression that an empty tank won’t have any impact on its operational conditions, so what is the purpose of the liquid level indicator then? P
