ABSTRACT:
A telephone signal or a radio signal is employed to terminate the through flow of gas through a gas meter to enable the flow of gas to a consumer to be terminated from a remote position. In one embodiment, a weighted arm includes a closure member to obturate an opening. The closure member is part of a weighted arm mounted on a rotatable rod bearing a toothed wheel engaged by a pawl which is operated by an electromagnetic arrangement which in turn is controlled by a signal. Provision is made for resetting the arrangement mechanically by the utilization of a key received in the key receiving end of the rotatable rod. In another embodiment, use is made of the fact that the gas meter includes a bellows and rotating arm arrangement. In this embodiment a rod is dropped into a position of interference with the rotating arm thereby to interfere with the flow of gas through the gas meter. In this embodiment resetting is effected by connecting an external power source to an electromagnet within the meter whereby to control the position of the rod which is dropped into interfering position with the rotating arm.
