Arrangement for use, in particular, in counting the revolutions of the rotor disc (5) of an electricity meter, comprises a marker (17) on the disc, and at least one electrode (18) located on the path on which the marker (17) moves. The capacitance variations occurring as the marker (17) rotates past the electrode (18) are used for counting the revolutions of the rotor 16 disc (5). Strontium titanate may be used as the marker. The electrode (18) is located on a component (22) which is clamped to the first plate of the meter, and which possesses all the necessary electrical connections (19, 21). The device is particularly suitable for converting single-tariff meters to multiple-tariff operation. <IMAGE> |
