Abstract

The laser methane remote sensor based on tunable diode laser absorption spectroscopy (TDLAS) technology uses open optical path instead of traditional absorption chamber to achieve zero-contact long-distance gas detection. It has the advantages of high measurement accuracy, fast response speed and large detection range. It can be applied to gas leakage monitoring places such as stations of urban natural gas pipeline network, transportation pipelines, underground comprehensive pipe corridors and industrial oil and gas drilling and production safety fields. This paper mainly introduces two kinds of laser methane remote sensor based on TDLAS, which are fixed reflection laser methane telemetry and echo reflection laser methane telemetry.
