Abstract: An electromagnetic pulse receiver for a flow meter, comprises a measuring wheel element to be driven in rotation by a flowing medium, a stationary axle which rotatably supports the measuring wheel element and is at least partially formed as a hollow axle with a cylindrical hollow space, a pulse wire sensor arranged in the cylindrical hollow space of the hollow axle and formed as a cylindrical probe, the probe having a probe head which carries a plurality of cylindrically arranged pulse wires, a receiver coil, and a cylindrical magnet yoke concentrically located inside the receiver coil, the probe also having an outwardly extending probe shaft with inwardly located electrical pulse conductors and an outwardly located holding element for holding the probe shaft, and a magnet device including at least one pair of magnets located near the hollow axle in the measuring wheel element, the magnet pair extending in a direction parallel to the hollow axle and magnetized in the direction with opposite polarity so as to

Abstract: An electromagnetic pulse pick-up unit, particularly for use in flow meters having small nominal width, comprises a pair of magnets arranged at opposite locations and with opposite polarity in a measuring gear of the flow meter. Concentrically arranged with the axis of rotation of the gear, there is provided a sensing unit assembled of a central pick-up cylinder, a sensing coil arranged around the portion of the cylinder facing the magnet, and a plurality of Wiegand wires distributed side by side in axial direction on the cylindrical outer surface of the pick-up cylinder in close proximity to the sensing coil. A pole ring of magnetically conductive material short circuits the ends of the Wiegand wires remote from the magnets.
