Abstract (en)
[origin: EP2863474A1] A gas meter includes a metal housing (410), a radiation conductor (440) configured to radiate a radio wave which is a high frequency signal, and a circuit board (441) having a power supply circuit (445) configured to supply high frequency power to the radiation conductor (440). A ground of the circuit board (441), i.e., a ground of the power supply circuit (445) is in electrical connection to the metal housing (410) via a lead wire (443) and one screw (423). A power supply point (442) for the radiation conductor (440) is located in a corner portion of the metal housing (410).
