Abstract
On occasion of provision of a technique for identifying an appliance, an attempt can be made to enhance computing speed and the accuracy of identification of an appliance while the amount of memory required for an apparatus is reduced. In a gas meter, an ultrasonic flowmetermeasures the quantity of a gas flowing through a flow pathat a given time interval, and a computation sectioncomputes a difference value of the measured flow at each given time. A difference value conversion sectionconverts a computed difference value into a code with reference to a flow rate class tableby which a plurality of difference value classes corresponding to a size of the difference value and codes representing the respective classes are associated with each other. A code sequence generation sectionfurther generates a measurement code sequence from an aggregation of codes at each given time, and an appliance identification sectioncompares the measurement code sequence with an appliance characteristic code sequence showing a characteristic code sequence of each gas appliance, thereby identifying a gas appliance that uses a gas.
