Floating roof tank operation

Thread Content

Does anyone know the regulations regarding the low liquid level in floating roof tanks? Are there any international standards that specify this? It must be the corresponding international standard

According to the GB50074-2014 Code for Oil Storage Tanks, 15 Automatic Control and Telecommunications, 15.1 Automatic Control Systems and Instruments 4: The set level for the low liquid level alarm in storage tanks should be such that cavitation in the pumps does not occur. For external floating roof tanks and internal floating roof tanks, the set level for the low liquid level alarm (measured from the bottom of the tank) should be at least 0.2m above the height at which the floating roof touches the bottom of the tank.
