Float for use in tank gauging systems of the type having a vertically supported guide (18). The float includes a donut-shaped body member (38) adapted to be positioned about the guide to ride freely with the liquid surface. A discharge tube (50) is positioned concentrically with the body member by a number of support members (46, 48). The discharge tube is positioned below the liquid surface and acts as a discharge electrode to maintain the path of least resistance for an electrostatic discharge of the float below the liquid surface. |
