Claims

[Claims for Utility Model Registration] (1) In a gas meter that measures the gas flow rate by transmitting the motion of a metering membrane that reciprocates due to the pressure of circulating gas to a counter via a crank mechanism, a part of the crank mechanism 1. A pulse generator for a gas meter, characterized in that a permanent magnet is provided in the permanent magnet, and a magnetically responsive element that generates a pulse by the magnetic force of the permanent magnet is provided within the magnetically sensitive range of the permanent magnet. (2) The pulse generator for a gas meter according to claim 1, wherein the magnetically responsive element is a reed switch or a magnetoresistive element. (3) The pulse generator for a gas meter according to claim 1, wherein the permanent magnet is attached to a portion of the large arm or the small arm that moves reciprocally or rotates.
