The Hall device is used for fixing the magnetic steel on the gas meter cover, the Hall device is integrated on the circuit board below the magnetic steel, when the meter cover is buckled, the Hall device is triggered to be opened, when the meter cover is disassembled, the Hall device is closed, and whether the meter cover is opened or not is judged through the high and low levels output by the Hall device. The method can only detect the state of a certain point on the gas meter, and the cover can be opened and the alarm is not triggered by only placing a large magnet covering the Hall device outside the meter shell.
There is therefore a need for a gas meter that solves the drawbacks of the cover that does not trigger an alarm when detached by a specific operation.
