Water meter

摘要

The water meter has a hydraulic transducer with a vane wheel (4), a meter housing (1) with water tight cover plate (2) and a bearing pin (3). The vane wheel has a bearing bush (6) with an upwardly open blind hole which accepts the bearing pin. The bearing pin extends through the cover plate. The vane wheel has magnets (5) which transfer the rotation of the wheel to a first gear wheel (9) of a transmission system, which can also have magnets (10,11) arranged at equal angular intervals in or on the gear wheel. The bearing pin also acts as the bearing pin for the first gear wheel.
