So the question is, can the local level gauge of the steam drum be removed?
No. The damage has a reason for it; this is not a common issue. The right thing to do is to find the cause and resolve it. It is not advisable to remove it when a problem arises. After all, it is a pressure vessel, so it’s better to follow the relevant regulations. For reference.
The level gauge (including the local level gauge), safety valve, and pressure gauge are the three main safety accessories of a steam drum – can they really be removed?
It belongs to a primary instrument; it is a safety accessory for boilers as specified in regulations such as the inspection procedures for special equipment and various equipment safety laws
No, it is designed to be displayed on-site as a monitoring device to ensure accurate readings even when other instruments fail to function properly; according to the regulations, it is not allowed to be removed
It’s not allowed. **The Technical Specifications for Special Equipment TSG-G0001-2012, namely the \"Regulations on Safety Supervision of Boilers\" (Boiler Regulations), contain the following provisions regarding water level gauges:
