Abstract A test apparatus for determining the operable condition of fuel level conl valves is presented. A sensor is connected to a fuel line for delivery of a test sample of fuel through the fuel line to a receiving system from a fuel supply source. At least one valve is disposed in the fuel line between the sensor and the fuel receiving system. A plurality of sense lines is connected from the sensor to a flow indicator and a pressure indicator such that simultaneous indication of the visual flow indicator and the visual pressure indicator within respective predetermined limits upon a delivery of the test sample of the fuel prior to delivery of the fuel through the fuel line indicates that the fuel level control valve is not properly operable.
A method for determining the operable condition of a fluid level control valve of a fluid receiving system prior to delivery of the fluid through a conduit to a fluid receiving system from a fluid supply source comprising the steps of: delivering from the fluid supply source a test sample of fluid through the conduit, and simultaneously determining the flow of the test sample of fluid through the conduit and the pressure of the test sample of fluid in the conduit, the simultaneous indication of fluid flow and fluid pressure within respective predetermined limits determining that the fluid level control valve is not properly operable.
