Abstract
A device for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device includes a valve housing having defined therein a valve aperture, a valve member movably mounted relative to the valve aperture. The valve member is arranged to be displaced reciprocally in a direction to selectively open and close the valve aperture. The device also includes a magnet mounted on or relative to the valve member, with the magnet being displaced by displacement of the valve member. A plurality of magnetic field sensors are mounted on the valve housing.
