摘要： An electricity meter capable of minimizing a risk of data destruction in case of lightning or surge that involves improperly high voltage is provided. The electricity meter includes a measurement part, an operation part, and an insulation part. The measurement part includes a detection unit to detect electricity consumption of an objective system and a transmission unit to wirelessly transmit data representative of the detected electricity consumption. The operation part includes a reception unit to receive the wirelessly transmitted data and an operation unit to process the received data into data representative of electric energy consumed by the objective system. The insulation part electrically insulates the measurement part and operation part from each other.

摘要： According to the present invention, the type of gas appliance in use can be identified and a gas leak can be detected, efficiently and accurately. The flow volume data noise removal means 21 removes noise from the instantaneous flow volume data measured by the flow volume measurement means 11, and from the data after noise removal, the flow volume data object extraction means 22 extracts data on the variable portion and the flat portion of the flow volume. The gas flow characteristics extraction means 31 extracts the “length”, “initial flow volume” and “sequence of transited regions” of the variable portion of the flow volume and the “length”, “average value” and “gradient” of the flat portion of the flow volume. In the appliance judgment means 41, the rule match search and point addition means 43 searches a rule having characteristics data which matches the characteristics of the variable portion and the flat portion of the flow volume, and adds points respectively for the type of gas appliance and for the existence of a gas leak. When the added points are not less than a previously established threshold value, then the appliance in use determination means 44 determines that a gas appliance of that type is in use, and outputs appliance type information as a judgment result.
