Abstract: Detecting a leak, or the like, with high accuracy on the basis of pressure and a flow volume acquired during use of fluid is made possible. A volume of gas flowing through a flow path 102 is measured by a flow volume measurement unit 106, and pressure is measured by a pressure measurement unit 108. Measured flow data and measured pressure data are input to an analysis unit 112, to thus analyze following of a pressure change by a flow volume change. An amount of flow volume change responsive to an amount of pressure change of a predetermined level or more is classified into a plurality of ranges by means of a predetermined threshold value, and a following flow value change is determined on the basis of determination conditions of the respective ranges of amounts of flow volume changes.

Abstract: A first communication unit (11) transmits, to an electrical home appliance (2), request information that requests electrical home appliance specifying information for specifying the electrical home appliance (2) after an approach instructing screen is displayed on a display unit (13), and receives response information including at least the electrical home appliance specifying information from the electrical home appliance (2) after the first communication unit (11) and the electrical home appliance (2) have approached each other within a communicable range, and a display control unit (141) switches a display screen to a menu screen that is unique to the electrical home appliance (2) on the basis of the response information received by the first communication unit (11).

Abstract: A gas meter device is provided which is configured in a manner that even if a user takes an unauthorized action such as the removal of a gas meter device in order to use gas without authorization, since the generation of a particular flow-rate change profile different from a normal flow-rate change profile of a gas appliance is detected, the sign of the tamper of the gas can be detected, whereby the tamper of the gas can be prevented. The gas meter device includes an appliance determining unit 6 for determining a gas appliance being used and a tamper determining unit 7 which determines that the gas is used without authorization in the case where the particular flow-rate change profile different from an appliance determining value registered in a registration storage unit 5 is generated.

Abstract: A flow rate measuring device has a flow rate measurement unit, an appliance registering unit, a calculating unit, a determining unit, a first appliance identifying unit, and a second appliance identifying unit. The appliance registering unit stores at least first gas flow rate variation profiles on activation of respective gas appliances coupled to a flow channel, and second gas flow rate variation profiles based on the control specific to the respective gas appliances. The first appliance identifying unit identifies which gas appliance is activated based on the first gas flow rate variation profiles on activation. When a determining unit detects a stop of any of gas appliances, the second appliance identifying unit identifies a gas appliance in continuous use by using the second gas flow rate variation profiles based on the control specific to the respective gas appliances.
