Abstract: Fluid, such as milk, is conducted into the meter through an inlet passage and received in a fluid receptacle at least a portion of which is movable with at least a portion of the movement being in response to receipt of the fluid with the fluid then being expelled from the meter through a discharge passage. A sensor senses the movement of the movable portion caused by receipt of fluid in the fluid reservoir and, responsive thereto, provides an electrical signal indicative of the amount of fluid received, which electrical signal is coupled from the meter for utilization purposes. In one disclosed embodiment, a rotating wheel has fluid receptacles at the rim to receive the fluid conducted into the meter with the fluid being later (in the rotation of the wheel) dumped from the receptacle and expelled from the meter through the discharge passage.
