Abstract

The present invention relates to a device for metering the flow of a fluid. A fluid-metering device for a hose or pipe, comprises: a body (10) having an inlet (12) and an outlet (11); an impeller (20) drivable by a flow of fluid through the device; a barrel (40), having an inlet (42) and an outlet (43), slidably mounted in the body (10) such that the barrel (40) is slidable between an open position wherein the barrel inlet (42) and outlet (43) are aligned with the body inlet (12) and outlet (11) such that a fluid can flow through the device and drive the impeller (20), and a closed position wherein the barrel inlet (42) and outlet (43) are offset from the body inlet (12) and outlet (11) such that a fluid cannot flow through the device, the barrel (40) being biased towards the closed position; and latching means (50) arranged to hold the barrel (40) in the open position, wherein a predetermined number of rotations of the impeller (20) will release the barrel (40).
