摘要： PROBLEM TO BE SOLVED: To provide a gas meter never performing an erroneous determination that a flow rate is present during interruption in the generation of a pulsation in a perfectly stopped state of the gas supply by the operation of a shut-off valve. SOLUTION: When the pulsation is generated in a perfectly stopped state of gas supply by the interrupting operation of the shut-off valve 10e, since the integrated value 10g of the momentary flow rate 10f of the gas by pulsation is 0 by positive and negative cancellation, it can be precisely determined whether the supply of gas is perfectly stopped or not even in the pulsation by the determination based on the integrated value of the momentary flow rate of gas. In this gas meter 10, a control part 10a restarts the shut-off valve 10e when the momentary flow rate integrated value 10g outputted by a momentary flow rate integration part 10b exceeds a prescribed value during the interruption by the shut-off valve after the shut-off valve 10e performs the interrupting operation once.

摘要： PROBLEM TO BE SOLVED: To provide an abnormality detection method for a gas meter and gas supply enabling enhancement of reliability in decisions related to warning operation. SOLUTION: CPU 12 checks that the absolute value of a difference in a flow rate ΔQS is equivalent to or more than that of reference flow rate QSK (|ΔQS|>=QSK) and then sequentially detects 'first decision shift state' where decision for gas G consumption state shifts from 'no flow rate change' to 'flow rate changed', and next 'second decision shift state' where it shifts from 'flow rate changed' to 'no flow rate change'. At this time, CPU 12 determines that a gas utensil 1 has operated when the difference in flow rate ΔQS varied within forward area during 'first decision shift state'-'flow rate changes'. Thus any operation of gas utensils can precisely be recognized at any time, so reliability in decision regarding warning action performance will be enhanced.

摘要： PROBLEM TO BE SOLVED: To suppress the power consumption of a meter power source using a battery. SOLUTION: The meter has an arithmetic control means 2 which obtains a flow rate change value from a gas flow rate measured this time by a flow meter 1 and a gas flow rate measured in a previous time, compares the flow rate change value with a flow rate change criterion, and, if the flow rate change value is judged to be less than the criterion and small, sets the drive period of the flow meter 1 to a longer period than a regular measuring period.

摘要： PROBLEM TO BE SOLVED: To compose a gas meter for eliminating a test operation due to mischief by preventing a circuit in a test mode from being operated unless specific magnetic force is given externally. SOLUTION: In the gas meter comprising a cutoff valve 11 for cutting off the supply of gas by detecting the generation of the causes of alarm/cut-off where criteria have been preset, and a test switch 5 for operating the cutoff valve by operating the circuit in a test mode, the test switch detects magnetic force with a specific level from the outside and operates the circuit in a test mode. As a result, the gas meter cannot be operated by magnetic force in the degree of that of a permanent magnet normally on the market, and is test- operated for the first time by stronger magnetic force so that the circuit in a test mode cannot be operated unless magnetic force with a specific level is given from a magnetism generator 15 that an engineer has, thus preventing mischief.

摘要： PROBLEM TO BE SOLVED: To provide a gas meter and a method for inspecting a gas meter, capable of shortening inspection time and flexibly corresponding with various assays and inspections. SOLUTION: Instrumental error inspection for an inspected gas meter 1 is performed by comparing the amount of passing gas calculated based on at least one of values outputted as inspection signals when the gas is caused to flow by an amount serving as reference over a specified inspection time with the amount of passing gas by means of a measurement standard. Further, on the gas meter 1 side, an integrated value for inspection is generated based on a value outputted as an inspection signal and is outputted as response from the gas meter 1 side.
