Abstract:
A device for detecting meter opening, the meter including at least a first structural element and a second structural element that are in a given position relative to each other when the meter is closed, said device comprising:a moving member connected to the first element and organized to take up a stable state or an unstable state as a function of the displacement of one of the structural elements relative to the other;holding means connected at least to the second element and co-operating with the moving member as a function of the displacement of one of the structural elements relative to the other, so as to hold said moving member in its unstable state and so as to enable it to go to its stable state;detection means suitable for determining the state of the moving member and for emitting an opening signal when the moving member is in a predetermined state; andcontrol means connected to the detection means for causing the moving member to return to one of its states, after an opening signal has been emitted by the detection means when the moving member has taken up the other state after one of the structural elements has been displaced relative to the other.
