    • PROBLEM TO BE SOLVED: To provide a highly reliable gas meter of a simple constitution which does not require oscillation detection means at a gas supply base or the transmission or reception of information between the gas supply base and individual users.
      SOLUTION: An oscillation detection means 10 detects oscillation data of a prescribe value or greater (for example, seismic intensity 5 or greater) via a sampling part. An oscillation data reception part 13b receives oscillation data detected by a plurality of other gas meters via a communication instrument 15. An earthquake determination means 13c collates the presence or absence of the reception of oscillation data from the other gas meters by the oscillation data reception part 13b with the presence or absence of the detection of oscillation data by the oscillation detection means 10 and determines the presence or absence of the occurrence of earthquakes on the basis of prescribed criteria of determination. A supply/shutoff means 13d shuts off gas pipes in the case that the earthquake determination means 13c has determined the occurrence of earthquakes and does not shut off the gas pipes and leave them open in the case that it has determined otherwise.
