Abstract
A floating roof tank is provided having a fixed vertical pole disposed through an opening in the floating roof. The vertical pole serves as both a gauging pole and an anti-rotational pole. The gauging pole is perforated to allow the free flow of liquid into and out of the gauging pole. A float is disposed within the gauging pole. The float has a pair of spaced-apart seals which effectively prevent the escape of vapor from within the tank through the gauging pole. Other seals effectively prevent the escape of vapor from within the tank around the periphery of the gauging pole and around the periphery of the roof itself. The gauging pole, in combination with the double sealed float, provides the operator of the tank with the ability to sample the tank from the top of the gauging pole, rather than having to stand on the floating roof itself.
