摘要： PROBLEM TO BE SOLVED: To suppress the power consumption of a meter power source using a battery. SOLUTION: The meter has an arithmetic control means 2 which obtains a flow rate change value from a gas flow rate measured this time by a flow meter 1 and a gas flow rate measured in a previous time, compares the flow rate change value with a flow rate change criterion, and, if the flow rate change value is judged to be less than the criterion and small, sets the drive period of the flow meter 1 to a longer period than a regular measuring period.

摘要： PROBLEM TO BE SOLVED: To compose a gas meter for eliminating a test operation due to mischief by preventing a circuit in a test mode from being operated unless specific magnetic force is given externally. SOLUTION: In the gas meter comprising a cutoff valve 11 for cutting off the supply of gas by detecting the generation of the causes of alarm/cut-off where criteria have been preset, and a test switch 5 for operating the cutoff valve by operating the circuit in a test mode, the test switch detects magnetic force with a specific level from the outside and operates the circuit in a test mode. As a result, the gas meter cannot be operated by magnetic force in the degree of that of a permanent magnet normally on the market, and is test- operated for the first time by stronger magnetic force so that the circuit in a test mode cannot be operated unless magnetic force with a specific level is given from a magnetism generator 15 that an engineer has, thus preventing mischief.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable gas meter of a simple constitution which does not require oscillation detection means at a gas supply base or the transmission or reception of information between the gas supply base and individual users.
SOLUTION: An oscillation detection means 10 detects oscillation data of a prescribe value or greater (for example, seismic intensity 5 or greater) via a sampling part. An oscillation data reception part 13b receives oscillation data detected by a plurality of other gas meters via a communication instrument 15. An earthquake determination means 13c collates the presence or absence of the reception of oscillation data from the other gas meters by the oscillation data reception part 13b with the presence or absence of the detection of oscillation data by the oscillation detection means 10 and determines the presence or absence of the occurrence of earthquakes on the basis of prescribed criteria of determination. A supply/shutoff means 13d shuts off gas pipes in the case that the earthquake determination means 13c has determined the occurrence of earthquakes and does not shut off the gas pipes and leave them open in the case that it has determined otherwise.

摘要： PROBLEM TO BE SOLVED: To adequately carry out shutting off or restoring of a gas flow passage depending on a condition of earthquake in a district by accurately grasping the condition of the earthquake in the district while effectively using a highly precise earthquake detection function of a highly precise earthquake sensor. SOLUTION: When an SI sensor 103 detects an SI value not lower than a prescribed level, a district supply judgment control section 104 in a district governor 100 controls a radio communication section 101 to allow it to send the detected SI value or an earthquake-sense shutoff command to a gas meter 200 in the district of the device itself by radio communication. In the case where an individual supply judgment control section 206 of the gas meter 200 receives the SI value or earthquake-sense shutoff command from the district governor 100, the individual supply judgment control section 206 controls an individual supply shutoff/restore section 202 and allows it to immediately shut off the supply of gas when the received information is the earthquake-sense shutoff command. When the received information is the SI value, the individual supply judgment control section 206 judges necessity of shutting off the supply of the gas or alerting in response to the level of the SI value and a device judgment section 205, or necessity of automatic restoring after the shutting off, and then controls the individual supply shutoff/restore section 202 or an alerting section 203 in response to the judgment result.

摘要： PROBLEM TO BE SOLVED: To provide a device and method for determining a gas appliance capable of easily and accurately specifying the type of a gas appliance and detecting gas leak at low cost. SOLUTION: When measuring signals i(t) and v(t) of gas flow rate and gas pressure are provided at a certain period to respective differentiating/integrating means 13 and 14 from a gas flow rate measuring section 11 and a gas pressure measuring section 12 disposed in a gas flow channel, the differentiating/integrating means 13 and 14 derive a differentiated value and integrated value for a circuit model, and provide them to an output resistance estimating means 15. The output resistance estimating means 15 calculates an output resistance estimated value from the differentiated value and integrated value, using the circuit model where an electric circuit is substituted for the gas flowing through the gas flow channel and an estimation expression for output resistance estimation preset for this circuit model. An appliance determining means 16 receives the estimated value of the output resistance from the output resistance estimating means 15, and determines the type of the gas appliance and existence of gas leak based on a variation pattern on the time axis of the inverse.
