DEVICE FOR DETERMINING THE CONCENTRATION OF MECHANICAL IMPURITIES AND FREE WATER IN A FLOW OF LIQUID HYDROCARBON FUEL Russian patent published in 2023 - IPC G01N21/53 G01N15/06 G01N21/85 

FIELD: measuring devices.

SUBSTANCE: device includes the first photodetector with a hemispherical lens, the second photodetector with an aspherical lens, a radiation source with an optical focusing system, the third photodetector with an aspherical lens, a reflective surface, and a holding element for holding the radiation source, photodetectors and the reflecting surface in a given relative position. The reflecting surface provides the main optical radiation path from the radiation source to the second photodetector, the first photodetector is located adjacent to the second photodetector outside the main optical radiation path. The optical axes of the first and second photodetectors are oriented essentially in the direction of the reflective surface. The third photodetector is located adjacent to the radiation source. The optical axes of the aspherical lens of the third photodetector and the optical focusing system of the radiation source are oriented essentially in the direction of the reflective surface.

EFFECT: possibility of simultaneous determination of concentration of mechanical impurities and free water and an increase in the accuracy of measurements.
