摘要： PROBLEM TO BE SOLVED: To provide an electronic gas flowmeter capable of obtaining data on measured gas flow rate by communication means. SOLUTION: A fixed quantity flow rate for every specified flow rate, which is calculated by a flow rate calculation part 3 from a flow rate signal which corresponds to the gas flow rate outputted from a flow rate detector 2, is outputted from a communication control part 7 outward, after the flow rate data signal is processed by a flow rate data processing part 6. When an electronic gas flowmeter 1 is measure-calibrated, the measuring test can be accurately and easily performed by comparing the measured value obtained from the flow rate data signal outputted from the communication control part 7 with a known flow rate value. Further, the measured data can be obtained even from a distant point when connection to the point is realized by a communication line.

摘要： PROBLEM TO BE SOLVED: To confirm whether a gas passage is surely intercepted or not so as to secure safe cutoff processing by confirming the condition of a gas valve after the operation control for cutting off or returning the gas valve for intercepting the gas passage is conducted. SOLUTION: This gas passage cutoff device 100 includes a cutoff valve confirming means 101 disposed in a control means 150, a cutoff valve driving means 901 and a cutoff valve 854 disposed in a gas introduction path in a gas meter. First, when one of a flow sensor 851, a pressure sensor 852 or an earthquake sensor 853 detects an abnormal value, a safety deciding means 900 gives a cutoff instruction for closing the cutoff valve 854 to the cutoff valve driving means 901, and the cutoff valve driving means 901 outputs a driving signal, thereby causing the cutoff valve 854 to conduct the cutoff operation. The cutoff valve confirming means 101 confirms the operating condition of the cutoff valve 854 in the lapse of designated time since the safety deciding means 900 gives a cutoff instruction to the cutoff valve driving means 901 to be transferred as cutoff valve condition information to the safety deciding means 900.

摘要： PROBLEM TO BE SOLVED: To provide a gas interrupter convenient for a gas user by preventing erroneous interruption due to temporary pressure variation of gas during use. SOLUTION: The gas interrupter comprises a pressure sensor 3 for detecting the pressure in a gas passage, a section 11 for making a decision whether the condition of pressure is normal or abnormal by acquiring input signals from the pressure sensor 3 periodically as pressure values, a section 12 for storing the pressure values, and a flow rate deciding section 13 for comparing the flow rate signal from a flow rate sensor 4 with an internal decision value and outputting an over flow rate signal. Only when an abnormal pressure flow rate monitoring section 14 makes a decision that a previous pressure value at the pressure value storing section 12 and a current pressure value detected at the pressure detecting section 11 are abnormal and the flow rate deciding section 13 outputs an over flow rate signal, an interruption request signal is delivered and an interruption valve driving section 15 closes a gas interruption valve 5.

摘要： PROBLEM TO BE SOLVED: To normally close a gas passage and to instantaneously open a gas passage during the use of gas. SOLUTION: An instantaneous flow rate deciding part 9 calculates an instantaneous flow rate value I from an instantaneous flow rate H detected by an instantaneous flow rate detecting part 8 to output a result. An external communication means 11 effects communication J to transmit a combustion demand signal K when a start of combustion is demanded from an external apparatus 10 and permit combustion when a combustion permission signal M is received. A combustion start deciding part 12 outputs an opening signal E and a combustion advisability decision signal L when the combustion demand signal K is received. The combustion permission deciding part 13 receives the combustion permission decision signal L. When a receipt instantaneous flow rate value I is available, a closing signal C is outputted and when the value is unavailable, the combustion permission signal M is outputted.

摘要： PROBLEM TO BE SOLVED: To judge whether there is gas leakage, on the basis of gas consumption on a holiday of a consumer. SOLUTION: A center receiving means 2 obtains 3 communication electric letter A from a center transmitting means 1, and outputs a pilot flame registration enabling signal B and a holiday data setting signal H. A holiday,judging part 9 obtains a holiday data I of a holiday maintaining part 8, and outputs a holiday signal J. A flow rate judging part 4 calculates a flow rate, on the basis of a flow rate pulse C per a constant amount of gas from a flow rate input part 3, and outputs a pilot flame registration value signal D to a pilot flame maintaining part 5, when the pilot flame registration is allowed. When the pilot flame is not allowed and a pilot flame registration value E is different from a calculated flow rate by comparison a gas continuous use signal F is outputted if it is not a holiday. In the case of a holiday, an alarm permission signal K is outputted at once. An alarm informing part 7 can give the alarm when an alarm permission signal G after continuation of a continuation timer 6 or an instantaneous alarm permission signal K is received.

摘要： PROBLEM TO BE SOLVED: To provide a gas shut off device preventing confusion due to the complication of information by limiting information quantity to give a centralized monitoring device at the time of an earthquake. SOLUTION: When a seismoscope 10 detects vibration, an earthquake judging part 3 judges the vibration to be an earthquake not less than a prescribed seismic intensity from its vibration pattern, etc., and outputs an earthquake defining signal. A shut off driving part 4 operates a shut off valve 9 by the input of the earthquake defining signal, and a communication control part 6 fetches only previously restricted earthquake time alarming information from an earthquake time alarming information storing part 7 and an external communication part 11 transmits it to the centralized communication part 11. When a recovering time measuring part 5 measures a prescribed recovering time, the fetching of alarming information by the part 6 is switched to normal time alarming information from a normal time alarming information storing part 8.
