Title:
GAS METER
Document Type and Number:
WIPO Patent Application WO/2019/202999
Kind Code:
A1
Abstract:
This gas meter is provided with a gas metering unit for metering gas, a gas shutoff valve for shutting off and supplying gas, a meter control unit (3) for controlling the metering of gas by the gas metering unit and the shutoff of gas by the gas shutoff valve, and a battery power source. The meter control unit (3) includes an earthquake sensing unit which measures acceleration to detect an earthquake, wherein the earthquake sensing unit operates in a measuring mode or a standby mode in which power consumption is suppressed compared with the measuring mode, and if the acceleration exceeds a prescribed threshold, transitions from the standby mode to the measuring mode and subjects the measured acceleration to noise determination to determine whether an earthquake has occurred. The meter control unit (3) is fixed to a meter casing (50) forming an outer shell, with a vibration isolating member (52) interposed therebetween.
