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 encircle the probe head during the rotation of the measuring wheel element. |
