FLOW RATE MEASURING DEVICE AND GAS SUPPLY SYSTEM EMPLOYING IT, METHOD FOR SPECIFYING GAS APPLIANCE

摘要

A flow rate measuring device has a flow rate measuring section, an appliance registering section, an operating section, a judging section, a first appliance judging section and a second appliance judging section. The appliance registering section stores the gas flow rate variation profile of each gas appliance connected with a channel at at least the starting time, and the gas flow rate variation profile based on the control specific to each gas appliance. The first appliance judging section specifies which gas appliance has started from the gas flow rate variation profile at the starting time. When the judging section detects stoppage of any one gas appliance, the second appliance judging section specifies a gas appliance which has been used continuously from the gas flow rate variation profile based on the control specific to the gas appliance.
