A liquid proving system is provided with a small volume liquid prover draining into a liquid holding tank that has capacity for multiple proving measurements. The small volume liquid prover is top-filled and bottom-drained. A liquid holding tank baffle assembly contains saturated vapor from an initial number of fills of the liquid holding tank within the small volume prover to improve overall accuracy of the proving measurements. When liquid is pumped into the prover evaporation of the liquid being pumped into the prover, and release of vapors from the prover and into the entire holding tank, is inhibited due to the saturated vapor environment established by a saturated vapor volume in the prover, which results in a more accurate prover measurement of liquid pumped into the prover. The saturated vapor volume is contained with a vapor tank baffle assembly in the liquid holding tank; a vapor conduit connecting the interior of the liquid holding tank to the interior of the prover; and the interior volume of the prover.

Vapor elimination liquid proving system with top or bottom fill and bottom drain prover
A liquid proving system is provided with a small volume liquid prover draining into a liquid holding tank that has capacity for multiple proving measurements. The small volume liquid prover can either be top-filled or bottom-filled, or exclusively bottom-filled. A liquid holding tank baffle assembly contains saturated vapor from an initial number of fills of the liquid holding tank within the small volume prover to improve overall accuracy of the proving measurements. When liquid is pumped into the prover evaporation of the liquid being pumped into the prover, and release of vapors from the prover, is inhibited due to the saturated vapor environment established by a saturated vapor volume in the prover, which results in a more accurate prover measurement of liquid pumped into the prover. The saturated vapor volume is contained with a vapor tank baffle assembly in the liquid holding tank; a vapor conduit connecting the interior of the liquid holding tank to the interior of the prover; and the interior volume of the prover.

Nozzle adapter for volumetric test and measurement apparatus
A nozzle adapter assembly is provided for adapting use of nozzles on liquid dispensing pumps with test and measurement equipment such as liquid provers, test measures and liquid proving systems. The adapter can be used with automatic shut-off nozzles through which the liquid may normally be dispensed.

Volatile liquid vapors formed during the pour of the volatile liquid from a volumetric test measure apparatus are contained in a pour vapor-containment apparatus that enhances the rate of vapor formation inside the pour vapor-containment apparatus. The interface between a flow control component on the test measure apparatus and a pour inlet on the pour vapor-containment apparatus creates a positive pressure, vapor-saturated environment so that a sufficient positive vapor pressure is maintained between the interior of the test measure apparatus and the pour vapor-containment apparatus when the flow control component is inserted in the pour inlet and the test measure apparatus is rotated about vertical during the pour and drain processes so that the vapor-saturated air formed in the pour vapor-containment vessel transfers during the pour into the interior of the test measure apparatus to replace the liquid that is poured out of the test measure apparatus.
A liquid proving system is provided with a bottom drain liquid prover draining into a holding tank. The fill opening of the prover has a prover fill opening self sealing assembly that remains closed except when a nozzle used to pump liquid into the prover is pushed through the opening of the prover fill opening self sealing assembly. The prover fill opening self sealing assembly may comprise a nozzle sealing gasket and a nozzle removed self seal assembly. There is a vapor conduit connecting the interior of the prover in the region of the fill opening and the interior of the holding tank to form a saturated vapor environment in the prover and holding tank from the vapors emitted from liquid in the holing tank. When liquid is pumped into the prover evaporation of the liquid being pumped into the prover, and release of vapors from the prover, is inhibited due to the saturated vapor environment in the prover, which results in a more accurate prover measurement of liquid pumped into the prover.
