Abstract
In order to quickly detect methane gas in real time, solve the defects of the traditional “extraction method” methane concentration measurement of gas pipeline based on pump suction or differential pressure sampling, and ensure the sensor’s performance requirements for resolution, a pipeline laser methane detector for in-situ direct measurement, based on TDLAS technology, has been developed. By studying effect of different chamber length on the resolution of different concentrations of methane gas, the gas chamber with length in the range of 4∼6cm can meet the performance requirements as much as possible, and the detector combine with the processing circuit designed with low power consumption for concentration demodulation. Test has shown that the measurement error in the range of 0%∼10% is less than ±0.05%CH4, and the measurement error is less than ±5% of the true value in the range of 10%∼100%.
