Abstract
A fuel dispensing apparatus comprises a flow conduit defining a fluid flow path. A plurality of fuel handling components are connected along the flow conduit. The fuel handling components include a fluid meter to measure quantity of fuel being dispensed and at least one valve to vary flow of fuel through the flow conduit. In some embodiments, the fuel handling components to be protected may further include a shear valve. A corrosion protection arrangement is in electrical communication with at least one of the fuel handling components. The corrosion protection arrangement is operative to inhibit formation of corrosion at an internal protected portion of the fuel handling component due to electrical current passing through liquid therein. The corrosion protection arrangement may include a reference circuit providing a selected DC potential to the protected portion.
