摘要： PROBLEM TO BE SOLVED: To provide a gas-blast breaking device to accurately and rapidly decide and monitor whether a circuit-breaking factor is changed for better and leakage occurs after the abnormal state of a gas apparatus is detected and cutoff is carried out. SOLUTION: The abnormal use of the gas apparatus is detected and a flow passage 1 is closed by a cutoff means 27. Thereafter, when the cutoff means 27 is released by a return means 28, a flow velocity is measured by a flow velocity detecting means 19, a flow rate is computed by a flow rate computing means 25, and it is decided by a leakage deciding means 29 whether or not leakage of a gas medium occurs.

摘要： PROBLEM TO BE SOLVED: To individually measure the integral flow rates of specific gas equipment which generates pulses of supply gas as the gas is consumed and normal gas equipment which generates no pulse at a time. SOLUTION: A physical quantity varying with the flow velocity of gas flowing a gas pipe 21 is measured, a pulse propagation decision means 11A decided whether or not pulses are propagated from the downstream side to the gas flowing in the gas pipe 21 according to the mentioned variation, and a pulse frequency calculating means 11B calculates the frequency of the pulses whose propagation has been decided by the pulse propagation decision means 11A, and a 1st flow rate integrating means 11C or 3rd flow rate integrating means 11F integrates the gas as the consumed gas of normal gas equipment 27 generating no pulses of the supply gas as the gas is consumed according to variation in the calculated frequency of the pulses and variation in the measured physical quantity or a 2nd flow rate integrating means 11E integrates the gas as the consumed gas of specific gas equipment 25 generating pulses of the supply gas as the gas is consumed.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption by automatically starting or releasing a shipping mode. SOLUTION: The gas pressure in a conduit is detected by a pressure sensor 103. When a controller 101 judges that the no-gas pressure state continues for a prescribed period in a no-shipping mode, it starts a shipping mode so that the gas flow is not measured by periodic sampling. When the controller 101 judges that the gas pressure state continues for the prescribed period in a shipping mode, it starts a normal operation mode so that the gas flow is measured by periodic sampling.

摘要： PROBLEM TO BE SOLVED: To adjust the remained rate of a prepaid card or the like at the time of closing a valve. SOLUTION: A card reader 33 reads out meter rates from a prepaid card 7, on which the meter rates are written corresponding to a prepayment of the amount of gas supply, a calculation part 35 converts the supply amount of gas from a gas meter 1 and substracts the converted meter rates from the meter rates read out by a card read-out part, and a card write-in part 39 writes in remaining meter rates obtained at the calculation part. Then, at the time of adjusting the meter rates, a meter rate adjuster 5 is connected to a controller 3, a communication part 51 transmits an adjustment instruction to the controller at the time of adjusting the remaining meter rates and receives the remaining meter rates in the controller transmitted responding to the adjustment instruction, a meter rate amount to money conversion part 53 converts the received remaining meter rates to the amount of money, and a control part 45 makes a cutoff vane 13 perform a close operation.

摘要： PROBLEM TO BE SOLVED: To measure accurate flow rate steadily without increasing power consumption. SOLUTION: An amplifying circuit 7 amplifies and outputs an original detection signal as a detection signal, a zero crossing detecting circuit 8 performs the zero crossing detection of the detection signal and outputs a zero crossing detection signal SZX to an AND circuit 10, and a timer circuit 9 outputs a detection control signal SCCMP at the timing delayed by a predetermined time t0 from the output timing of a trigger signal. The AND circuit 10 obtains the logical product of the zero crossing detection signal SZX and the detection control signal SCCMP and outputs a flow rate detection signal SFL, and a control computational part 11 measures propagation time on the basis of the output timing of the trigger signal STRG and the output timing of the flow rate detection signal SFL and calculates the flow rate of a fluid. Therefore, there is no need for exciting resonators 4 and 5 in advance, it is possible to perform the stable and highly accurate measurement of propagation time, it is possible to reduce power consumption in comparison with the case of performing excitation, and it is possible to perform the highly accurate measurement of flow rate.

摘要： PURPOSE:To eliminate the need for visiting a gas user house every time inspection is performed by connecting many terminals to a center by communication channels, sending cutoff request signals for cutoff valves of the terminals out of the center at a distance at any time, and informing the center of the detection result of a minute gas leakage according to the requesting signals. CONSTITUTION:When a cutoff requesting signal input means 32a1 inputs a cutoff requesting signal sent from the cutoff requesting signal sending means 11a of the center 11 through a communication channel L, a cutoff valve cutting- off means 32a2 cuts off the cutoff valve 17. At this time, gas is cut off in a gas pipe 20 from the cutoff means 17 to gas equipment 19. Here, when a minute gas leakage detecting means 32a3 detects a minute gas leakage in the gas pipe 20, an informing means 32a4 informs the center 11 of its detection result through the communication channel L. Therefore, the center 11 inspects the gas leakage at any time without sending an inspector to the gas user house where the gas equipment 19 is installed.

摘要： PURPOSE: To allow the controller to surely collect the utility charge by allowing the user for a supplied material to use the supplied material with advance payment of the charge. CONSTITUTION: A storage medium D inserted to a medium insert port E is read by a read means F and the data are stored in a storage means G as supply amount data. A switching control means I controls a supply path switching means B based on the supply amount data. Simultaneously a data revision means conduct arithmetic processing to decrease the supply amount data by a supply amount detected by a supply amount detection means C. When the read means F reads the supply amount data from the storage medium D, an invalidate means H invalidates the storage content of the storage medium D. Thus, the switching control means I shuts the supply path A when the supply amount of a supply material represented by the supply amount data stored in the storage medium D is zero to use the supplied material only within a range of the supply amount represented by the supply amount data.

摘要： PURPOSE: To collect the charge surely on pre-payment basis by stopping supply of gas when the amount in matching with a supply amount stored in a storage medium is supplied. CONSTITUTION: When the user purchases a memory card 6 storing a frequency in response to a gas flow in advance and inserts the card to a socket SC2 , a CPU 18 uses a frequency input revision circuit 25 to read the frequency of the memory card 6 and displays it on a frequency display device L4 via a display drive circuit 24. When an open switch SW2 is operated in this state, a shut-off valve 17 is open via a shut output circuit 22. When the user uses gas, a flow pulse is received from a remote gas meter 16. The CPU 18 decrements the frequency stored in the memory card 6 depending on the flow pulses and allows the frequency display device L4 to display the remaining frequency. When the frequency reaches a specified frequency or below, a buzzer B1 is energized and when the frequency reaches zero, the shut-off valve 17 is closed.

摘要： PURPOSE:To attain metering surely by accessing a gas meter for a prescribed period so as to detect whether or not a metering data is received normally. CONSTITUTION:A communication controller 1 in the metering system counts the data every time a prescribed flow flows to a gas flow path 2, a gas meter 3 is connected via a signal line 4 and the data is sent to the center 6 via a communication line 5. An access means 1a, independently of the call from the center 6, accesses the gas meter 3 for each prescribed period shorter than the metering data collection period and a detection means 1b detects the transmitting state via the signal line 4 with the gas meter 3 at the access by the access means 1a and when the detection means 1b detects that the transmission is not implemented normally, a fault notice means 1c informs a fault to the center 6 via the communication line 5.
