Tank level gauge in the tank farm
Thread Content
I would like to ask fellow sailors: what model is suitable for liquid level gauges in storage tanks in tank farms?
The selection of a level gauge is related to factors such as temperature, pressure, and the properties of the material
Commonly used remote transmission methods such as radar, double flange, and servo systems need to be determined based on specific circumstances.
Store flammable and explosive liquids at normal temperature and pressure!
If the liquid does not stick or crystallize, guided wave radar should work well; if the tank is not very tall, double flanges can be added.
For storing flammable and explosive liquids at normal temperature and pressure, magnetic flap level gauges can be used if the height of the storage tank is 10 meters or less
As I recall, the regulations previously required that storage tanks be equipped with level gauges based on two different principles; now three such gauges are required, and magnetic flap level gauges can be used on site. Please check the specifications.
May I ask which standard can be referred to? Thank you!
Only one standard could be found: SH3007-2014, Design Code for Tank Areas in Petrochemical Storage and Transportation Systems. It requires one liquid level indicator for design purposes, and a separate alarm interlock device. I’ll let you know once I find a new one. This specification is available online, and it can also be sent to you by email.
HaiChuan has a webpage that compiles the design specifications related to tank areas; you can take a look there: the latest and most comprehensive design standards for tank areas – http://bbs.hcbbs.com/thread-1646430-1-1.html (Source: HaiChuan Chemical Forum website)
