Metering apparatus including wall portions which define an elongate generally upright cavity of substantially uniform cross-section and an inlet to the cavity to enable fluid which is to be metered to be fed into the cavity. The apparatus further includes a pressure transducer in communication with fluid in the cavity when the apparatus is in use, to provide a signal indicative of the amount of fluid in the cavity above the transducer.

Metering apparatus for fuel injector flow test

Metering equipment for metering fluid flow through an injector valve, comprising metering means and locating means arranged to locate such a valve in fluid communication with the metering means. The metering means are upstream of the locating means.

Metering equipment

Equipment for monitoring the performance of an engine fuel injector valve includes a source of pressurized fluid and an injector valve head connected to an injector valve and the source so that pressurized fluid is delivered to the valve. A regulator compensates for changes in pressure of the fluid and enables the change to be effected and maintained. A flow monitor is in the fluid path between the source and the head to monitor the flow of fluid. The source of pressurized fluid maintains a level of pressure in excess of a desired operating pressure. A fluid flow control coupled to a pressure sensor, near the test head indicates the pressure therein so that the flow control effects flow through the fluid path to maintain the pressure at the head.
