摘要： Method for acoustically locating leaks in underground or aboveground piping systems, in which at least two noise data loggers receiving the leak noise and being arranged in mutual distance from one another are brought in physical contact with the piping system to be examined and measure simultaneously the noise level (dB) and the frequency of a leak, whereas both measured values of frequency and noise level are combined in a single value (ESA), whereas the ESA value is calculated from the decimal logarithm of the frequency of the leak noise multiplied with the logarithmic level value of the leak noise multiplied with a constant factor.

摘要： A real time remote leak detection system includes leak detection sensor nodes configured to be operated according to a plurality of sensor management modes. The plurality of the leak detection sensor nodes being installed on a underground pipe and at least one network node configured to cause an NTP (Network Time Protocol) node to synchronize timing of the leak detection sensor nodes when a time of the NTP node is set through a timing source such as a Global Positioning System and the leak detection sensor nodes enter a specific sensor management mode. The system may transmit leak sound data collected in real time in a sensor node wirelessly installed in a pipe to a control center to check whether a leak of the pipe occurs and identify leak location as well.

摘要： A solenoid gas meter mounting bracket valve may be used to shut down the flow of fuel, such as natural gas, to a building. The solenoid valve may be incorporated with the gas meter bracket, as a single unit. This configuration may be safer and more secure than a separate valve, which may be damaged when installed at the exterior of the building. The solenoid gas meter mounting bracket valve may not only secure the gas meter, for example, but may also be the solenoid valve for controlling the fuel flow. The solenoid valve may be closed from signals received from various detectors located, for example, in the structure and in the ground, do detect carbon monoxide, carbon dioxide, radon, air quality, and the like.

摘要： A challenge to be met by the present invention is to enable appropriate setting of safety function according to a use environment and enhance safety function. An IC card (118) stores data pertaining to the quantity of available gas and at least one safety function program. An IC card reading unit (122) reads information stored in the IC card (118). From the read information, an IC card determination unit (126) determines whether or not the IC card (118) is normal. A safety function detection unit (128) detects a safety function program from the read information and stores the program in a safety function storage unit (130). When the IC card (118) is normal, a function setting unit (116) imparts a safety function program to a monitoring unit (112). A remaining available quantity count unit (124) determines a remaining quantity of available gas from the read quantity of available gas and a flow determined by a flow computing unit (110). A control unit (114) cuts off a gas supply when an event fulfilling operating conditions for safety function has arisen and when the remaining available quantity has come to a predetermined remaining quantity.
