An apparatus for operating an electromagnetic valve, associated to a gas meter, and operated to stop, or allow, a flow of gas through the meter (1) includes: an electronic consumption measuring device (4), which generates in output electric signals representing the quantity of gas, which flows through the meter (1); a central unit (C), which receives in input the electric signals generated by the measuring device (4) and includes means for transmitting the data concerning the gas consumption, by electromagnetic waves. Moreover, the apparatus includes an electric, functional connection between the central unit (C) and the electromagnetic valve (3), while the central unit (C) includes also means for receiving significant data by electromagnetic waves. |
