A Gauge Pole Cover, also known as a Gauge Pole Sleeve, Gauge Pole Seal or Gauge Pole Cover Assembly, is an emission-control device installed around the gauge pole (stilling well) of External Floating Roof Tanks (EFRTs) and Internal Floating Roof Tanks (IFRTs). Its primary function is to minimize hydrocarbon vapour emissions through the annular gap between the gauge pole and the floating roof while allowing unrestricted vertical movement of the floating roof during tank filling and emptying operations.

The Gauge Pole Cover is designed with a flexible bellows arrangement manufactured from elastomer or reinforced fabric, allowing it to expand and contract according to the movement of the floating roof. This flexible sealing arrangement maintains an effective barrier around the gauge pole while accommodating variations in roof position during normal tank operations.

The system helps reduce hydrocarbon evaporation losses, control Volatile Organic Compound (VOC) emissions and minimize vapour leakage through floating roof gauge pole openings. It also supports environmental compliance and improves the overall emission-control performance of petroleum storage tanks.
