Abstract
Battery-free meter for flowing media, in which a rotor body (sleeve 4) which is fitted with permanent magnets (6, 7) and is driven in a rotary fashion by the medium is arranged in the pipeline (34) carrying the flowing medium (8) and in which the rotating magnetic field generated by this acts on at least one Wiegand sensor (25, 26), which is arranged outside the flowing medium in the area around the meter, wherein a housing part (15) which is open on at least one side sealing to the interior of the pipeline (34) engages with the pipeline (34) and around which the flowing medium at least partially flows, such that the external periphery of the housing part (15) is at least partially embraced by the rotor part (sleeve 4) which is driven in a rotary fashion and generates the rotating magnetic field and that at least one Wiegand sensor (25, 26) is arranged in the housing part (15).
