Gas meter and gas blocking restoration determining system

A gas blocking restoration determining system comprising:

• gas meters corresponding to consumers' places;
• and
• a center server that is communicable with the gas meters, wherein:
• each of the gas meters includes
• a flow rate measurer that is located at a passage through which gas to be supplied to a gas appliance located at the consumer's place flows, and measures a flow rate of the gas flowing through the passage,
• a self-diagnoser that performs self-diagnosis,
• a vibration detector that detects vibration,
• a calculator that calculates an earthquake index value based on the vibration detected by the vibration detector, the earthquake index value indicating the scale of an earthquake,
• a blocker that switches from an open state to a closed state when the earthquake index value is not less than a predetermined value, the open state being a state where the gas is allowed to flow through the passage, the closed state being a state where the flow of the gas in the passage is blocked, and
• a communicator that communicates with the center server;
• and
• the center server includes an inspection method determiner that determines an inspection method for the gas meter corresponding to each consumer's place based on a result of the diagnosis by the self-diagnoser and the earthquake index value which have been acquired from the gas meter.
