We conducted shaking-table tests to clarify the seismic shutoff features of intelligent gas meters stopping the supply of gas during earthquakes where Tokyo Gas Co., Ltd., provides service, and studied the relationship between earthquake movement and gas meter shutoff based on 200,000 monitored archive data points showing shutoff situations during actual seismic movement.
