Add pressure monitoring before and after the breather valve? How has everyone set it up?
Thread Content
Article 6.7.1 of the \"Safety Management Specifications for Atmospheric Storage Tanks of Flammable Liquids in Chemical Enterprises\" (AQ3063-2025) states that \"for tanks located in areas where the average temperature in the coldest month of the year is below 0°C, anti-freezing measures shall be taken for the breather valves and flame arresters.\" The absence of pressure monitoring before and after the tanks poses a risk of failing to detect faults in the breather valves or pressure abnormalities in a timely manner. How do I add pressure gauges before and after this breather valve? Are all of them equipped with transmitters or local pressure gauges?
There are flame-arresting breather valves with jackets; warm water or steam can be used, along with heating for the pipes connected to the breather valves. For pressure gauges, it is recommended to use flanged diaphragm pressure transmitters that allow for remote transmission
