摘要： PROBLEM TO BE SOLVED: To provide a gas sensor for avoiding the occurrence of unneeded gas shut-off by transitory failure.
SOLUTION: A gas meter 1 comprising a controller 2; a flow rate sensor 3; an external sensor 4; an isolation valve 5; a display section 6; and a communication I/F 7. The gas meter 1 is connected to a setting apparatus 8 via the communication I/F 7, and further is connected to a monitoring center 72 via a telephone line 71. In this case, the controller 2 acquires data from the flow rate sensor 3 at a fixed period, performs flow rate sensor failure judgement operation, based on the data, and stores failure in the controller 2 as "flow rate sensor failed state" when the controller 2 detects the failure in the flow rate sensor 3 for a specific number of times continuously.

摘要： PROBLEM TO BE SOLVED: To achieve resetting without using any monitoring sensors and communication equipment when a strong earthquake cuts off gas that cannot be reset in a gas meter for detecting the earthquake for cutting off gas. SOLUTION: After a controller 19 detects a strong earthquake for cutting off gas that cannot be reset, measurement for specific time is started. When a phenomenon, such as earthquakes, is not detected during the period, the cutoff of gas that cannot be reset is set to the cutoff of gas that cannot be reset, thus performing control so that gas can be used by pressing down a reset switch and automatic reset.

摘要： PROBLEM TO BE SOLVED: To enable safely and surely the reset of a gas meter even when two or more causes having the same order of priority are generated in the gas meter detecting an abnormality and issuing a gas shutoff alarm or the like.
SOLUTION: When two or more abnormalities causing shutoff or alarm are detected, and a release order is required for reset from the shutoff state caused by a shutoff cause or from an alarm state caused by the alarm cause, and the orders of priority of each shutoff cause and alarm cause are the same, even after releasing one shutoff cause or alarm cause, a controller 18 does not release the other one or more shutoff causes or alarm causes, holds the causes internally, and thereby releases each cause, while confirming the causes one by one.

摘要： PROBLEM TO BE SOLVED: To provide a gas meter to shut off gas upon detecting an earthquake that makes resettable a non-resettable gas shutoff triggered by a strong earthquake, without using a monitoring sensor or a communication device. SOLUTION: After triggering a non-resettable gas shutoff upon detecting a strong earthquake, a controller 19 starts to measure for a predetermined time, and if there are no events detected, such as earthquakes, or a test shutoff is performed in the duration, makes the non-resettable gas shutoff resettable so that gas can be used when a reset switch is pressed or through automatic reset.

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter that determines inverse connection for appropriate use even if the flowmeter is connected opposite to a normal connection direction.
SOLUTION: A flow rate calculation means 21 determines the flow direction of gas from a signal acquired by a flow rate sensor 3, calculates a flow rate, where a minus sign is added to the absolute value of the flow rate, when gas flows in a forward direction, and calculates the flow rate, where a minus sign is added to the absolute value of the flow rate, when the flow is in the opposite direction. An inverse connection judging means 22 integrates the flow rate being calculated by the flow rate calculation means 21, and measures the integration time. Then, the integral flow rate within a specific time is equal to or less than a specific value, the connection is judged to be opposite. A flow rate sign switching means 23 switches the plus/minus of the flow rate being outputted by the flow rate calculating means 21 when the connection is judged to be in the opposite direction (namely, when the sign of the flow rate is positive and negative, the sign is set to negative and positive, respectively) for outputting.

摘要： PROBLEM TO BE SOLVED: To provide a gas meter capable of determining whether a governor is built in a gas consumption equipment used in a user side or not, without requiring fine valve opening regulation for a cut-off valve, even when a low flow rate of gas consumption condition is continued in the user side, and capable of determining the presence of generation of gas leakage.
SOLUTION: A gas equipment using condition determination part 7 determines the occurrence of the gas leakage, or that the gas consumption equipment not provided with the governor is used in a downstream, when a reduction-directional change of a level of a prescribed variation or more is detected in response to pressure reduction generated inside the gas meter in own house caused, for example, by an influence of receiving passively pressure drop of gas in a neighboring house via a gas pipe or the like, and when the gas flow rate is not increased to the prescribed variation or more even after a prescribed time lapses.
