Abstract: Setting safety function, as appropriate, according to a user environment is enabled, thereby enhancing safety function. According to selection information from a safety function selection unit 120, a function setting unit 116 sets arbitrary function among a plurality of functions as safety function pertaining to usage of a gas. When operating conditions for safety function are fulfilled, a monitoring unit 112 detects malfunction, which would arise during usage of a gas, and outputs a safety signal to a control unit 114 in accordance with the set safety function. In accordance with a safety signal from the monitoring unit 112, the control unit 114 cuts off a gas supply when an event fulfilling operating conditions for the set function has arisen. When an event fulfilling operating conditions for an unset function has arisen, a communication unit 124 reports occurrence of malfunction pertaining to unset function to the monitoring center 200.

Abstract: A challenge to be met by the present invention is to enable appropriate setting of safety function according to a use environment and enhance safety function. An IC card (118) stores data pertaining to the quantity of available gas and at least one safety function program. An IC card reading unit (122) reads information stored in the IC card (118). From the read information, an IC card determination unit (126) determines whether or not the IC card (118) is normal. A safety function detection unit (128) detects a safety function program from the read information and stores the program in a safety function storage unit (130). When the IC card (118) is normal, a function setting unit (116) imparts a safety function program to a monitoring unit (112). A remaining available quantity count unit (124) determines a remaining quantity of available gas from the read quantity of available gas and a flow determined by a flow computing unit (110).

Abstract: To provide a flowmeter capable of enhancing metering resolution to thus effect accurate metering. When a fluid to be measured is supplied to or discharged from a metering chamber 4, a membrane 11 provided in the metering chamber 4 is reciprocally actuated, and a rotation section R1 performs rotational movement in association with reciprocal movement of the membrane 11. At this time, since the rotation section R1 is provided with a magnet 5 or a direction sensor 6, the magnet 5 or the direction sensor 6 also effects rotational movement. The direction sensor 6 detects rotational movement, to thus determine a relative position between the membrane and the rotation section. Thus, the position of the membrane 11 can be detected, and metering resolution is enhanced. Thus, accurate metering can be performed.
