Abstract

Disclosed are apparatus and methodology for providing safe reconnection of remotely disconnectible gas meters. In accordance with the present subject matter, a gas metering device is provided with a remotely controllable valve and has associated therewith indicia uniquely identifying the meter. A gas company representative or other authorized person must be physically present to read the meter associated data, enter corresponding data into a handheld device, and transmit a signal from such handheld device to the meter to initiate reclosure. In such manner, physical presence of a gas company representative is required at the time of reconnection to provide other services and functionality such as equipment inspection and/or pilot relighting as required for safety considerations.
