Claims

[Claims for Utility Model Registration] (1) A method for converting the reciprocating motion of a diaphragm membrane based on the pressure difference of gas flowing inside the measuring chamber body into a rotational motion of a crankshaft, and for a member that is linked to the rotational motion of the crankshaft. Using movement to activate magnets,
A gas flow rate detection device for a gas meter that integrates and displays a gas flow rate using a pulse signal from a flow rate sensor that can detect this includes an armrest that transmits the reciprocating motion of the diaphragm membrane to the crankshaft as a rotational motion, and a surface of this armrest. On the other hand, a gas meter is equipped with a plurality of magnets that are fixed at regular intervals along an arc centered on a rotational fulcrum and repeatedly move toward and away from the flow sensor by the rotation of the armrest. Gas flow rate detection device. (2) The reciprocating motion of the diaphragm membrane based on the pressure difference of the gas flowing inside the metering chamber body is converted into the rotational motion of the crankshaft, and the movement of the members linked to this rotational motion of the crankshaft is used to operate the magnet. let me,
In a gas flow rate detection device of a gas meter in which a pulse signal from a flow rate sensor accompanying this integrally displays a gas flow rate, the gas flow rate detecting device rotates in conjunction with the rotational movement of the crankshaft;
a valve that alternately switches so that the gas pressure acting on both sides of the diaphragm membrane becomes inflow gas pressure or outflow gas pressure; A gas flow rate detection device for a gas meter, comprising: a plurality of magnets that are fixed to the flow rate sensor and repeatedly move toward and away from the flow rate sensor according to rotation of a valve.
