The Flowing Fourier-transform infrared spectrometer in the near-infrared range is designed for online monitoring of the quality of light petroleum products such as gasoline, kerosene, and diesel fuel. Fourier-transform spectrometers are installed at critical points of pipelines for continuous quality control of transported petroleum products. The spectrometer is equipped with a fiber-optic measuring probe, allowing measurements directly within the pipeline.
