Abstract: 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.

Abstract: 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.

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.

Abstract: 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.
