A conventional appliance monitor only deals with a gas consumption volume or security information at gas cutoff time, so that the monitor cannot comply with the social needs for the desire to know the influence of the use of a gas burner appliance (a CO2 emission, for example) against global environment. A CO2 emission calculation unit (5) calculates a CO2 emission, a comparative CO2 emission and a difference between the CO2 emission and the comparative CO2 emission in accordance with an gas appliance in use by a user and a gas flow rate signal of the appliance outputted from an appliance discrimination unit (2), CO2 emission data of the gas appliance stored at a CO2 emission data memory unit (3), and comparative CO2 emission data for the gas appliance stored at a comparative CO2 emission data memory unit (4), thereby making it possible to obtain the CO2 emission, comparative CO2 emission, and the difference between the CO2 emission and the comparative CO2 emission caused by the gas appliance in use by the user.

A gas meter and a gas metering system that allow the safety functions to be set up appropriately depending on the use environment and the like for improving the safety functions. An IC card (118) stores data on a usable amount of gas and at least one safety function program. An IC card read section (122) reads the information stored on the IC card (118). An IC card judgment section (126) judges whether the IC card (118) is valid or not depending on the readout information. A safety function detection section (128) detects the safety function program from the readout information to store the detected safety function program on a safety function storage section (130). A function setup section (116) gives the safety function program to a monitor section (112) if the IC card (118) is valid. A usable remaining amount counting section (124) determines a usable amount of gas in accordance with the readout data on the usable amount of gas and a flow rate determined by a flow rate calculation section (110). A control section (114) shuts off feeding of gas when an event satisfying the operating requirements of the safety function takes place and when the usable remaining amount reaches a predetermined remaining amount.

Intended is to make more prompt and proper the counter-measures of a flow rate measuring device against a new event in a use environment. In a gas meter (100), an ultrasonic flow meter (104) measures the flow rate of a gas to flow in a passage (102), and a new event detecting unit (108) detects it from the flow rate pattern of the measured flow rate that a new event or an event not existing in the previous use environment has newly occurred in the use environment of the fluid. A transmit-receive unit (110) transmits a new event signal indicating the new event detected by the new event detecting unit (108), to a center device (200) via a network (300). The new event is exemplified by the introduction of a new gas tool into a user's house, an abnormal use of the tool, or the detection of a CO generation.

A behavior different from those of the steady state of an appliance during use of the appliance is detected, and an improper use can be detected. A gas meter (100) has an ultrasonic flow meter (104) which measures the flow of gas flowing through a passage (102). A new event detecting section (108) detects a nonsteady behavior different from those in the steady state in an environment where fluid is used as a new event which is not present in the past use environment from the flow pattern of the measured flow. With this, an improper use such as ignition failure or malfunction can be detected.

The invention relates to an odorant for imparting a warning smell of a gas leak to gas and a process for production of town gas with the odorant. The odorant is a mixture of n-butyl isocyanide with 2-hexyne and/or 1-pentyne; a mixture of ethyl isocyanide with 2-hexyne and/or 1-pentyne; a mixture of n-butyl isocyanide, ethyl isocyanide, 2-hexyne and 1-pentyne; 2-hexyne, 1-pentyne, or 1-butyne, or a mixture of two or more of them; or a mixture of 2-hexyne and/or 1-pentyne with 3-methylbutanal and/or t-butylmercaptan. Since the odorant is completely free from sulfur, fuel gas containing the odorant does not generate sulfur oxides even in combustion to contribute to environment pollution control. Further, such fuel gas can be favorably used in fuel cells.
