Abstract
A fire prevention safety device for a gas meter (3) has closure means (4, 4′, V) that can be activated by heat to interrupt the gas supply into the gas meter (3) in the event of a fire. The gas meter (3) is arranged in a bypass (2) of a gas pipe (1). At least one of the aforementioned closure means (4, 4′, V) for interrupting the gas supply is in each case arranged in the bypass (2) in the flow direction upstream and downstream of a sensor (31) belonging to the gas meter (3). The device permits a cost-efficient, simple and effective fire prevention safeguard, in particular for electronic gas meters.
