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.

摘要： PROBLEM TO BE SOLVED: To add a function of generating information of blocking gas supply to a cooking stove or supply warning information to a gas meter, and to provide the gas meter with a gas supply monitoring function generating the information in the most suitable state.
SOLUTION: The gas meter is equipped with a used instrument determination means X2 for determining the kind of a gas instrument used on the downstream side from a change pattern of gas flow rate supplied to the downstream side, and a single usage determination means X3 comprising a gas flow rate storing means m for storing the gas flow rate over time until a first time limit and a first clocking means X4a for clocking continual operation of the cooking stove. When an operating time of the cooking stove exceeds the first time limit, the single usage determination means X3 determines whether the cooking stove is used in a state of being regarded as a single usage status, based on change of the gas flow rate stored in the gas flow rate storing means m. Thus, the gas meter generates the gas supply blocking information or the supply warning information.

摘要： PROBLEM TO BE SOLVED: To estimate the remaining capacity of a battery without affecting the life of the battery. SOLUTION: A remaining capacity estimating section 6 stores the average current consumption per unit time consumed by various sections operated by the battery 5 in a stationary state and stores the current consumption for one occurrence of an abnormality. The current consumption in the stationary state is calculated by measuring the operating time, counting the number of occurrences of the abnormality, and multiplying the average current consumption and the measured operating time together. The current consumption in an abnormal state is calculated by multiplying the current consumption for one occurrence of the abnormality and the measured number of occurrences of the abnormality together. The calculated current consumption is subtracted from the initial current capacity of the battery 5.
