Floating Roof Tanks

Floating roof tanks are normally used for aviation fuels or other products for which the amount of water in the product must be minimized.

Floating roof tanks have a moveable roof that floats on top of the product in the tank. A tank with a floating roof displaces a certain amount of liquid around its edges and up into the tank hatch. With such tanks, you must make a correction to the product measurement. The amount of displacement depends on the weight of the roof.
