gas pipeline leak monitoring system

摘要

1. The system control gas pipeline leaks, including primary converters physical feature leak into electrical signals, measuring and computing system consisting of the measuring unit modules and a signal processing unit to determine the magnitude and leak location link-vapor selecting and transporting apparatus mixture consisting of at least two nozzles, arranged along the length of the controlled volume and communicated with the lower ends of them, characterized in that as primary transform ovateley physical feature leaks used gas sensors, the measuring and computing system is further provided with unit function modules to start monitoring unit signal processing in excess of the output signals of the measuring modules intrinsic noise, wherein the gas sensor outputs are respectively connected to the inputs of a block measuring modules communication lines, the outputs of the measuring modules unit connected to the inputs of functional unit modules, and their outputs are connected to inputs of the processing unit signalov.2. The system of claim. 1, characterized in that the physical feature of transducers used ammiaka.3 leak sensors. The system of claim. 1, characterized in that the primary transducer is used a physical feature of a leak of hydrogen sensors.
