Measuring device for quantifying different proportions of a fluid mixture, and a corresponding method

摘要

The invention relates to a measuring device (1) for quantifying different proportions (4, 5, 6) of a fluid mixture (3), in particular a gas-water-oil mixture, with a measuring channel (2), through which in operation Measuring device (1) the fluid mixture (3) flows with a radiation source (12) for irradiating the through the measuring channel (2) flowing fluid mixture (3) with a radiation, and with a detector unit (13) for detecting a through the fluid mixture (3) transmitted radiation portion of the radiation, as well as with a filter element (7), which in a beam path (14, 15) of the radiation between the radiation source (12) and the measuring channel (2) is arranged and in at least a first Direction transverse to the beam path (14, 15) within a in the operation of the measuring device (1) through the radiation source (12) radiated filter area a plurality of absorption regions (8, 9) each having different absorption properties for a Spektru m having the radiation, wherein the detector unit (13) detector points (16, 16 ', 16' '), by means of which only one integrated over the spectrum of the radiation total intensity (Imeas H, Imeas L) of the radiation detectable and thus evaluable, to improve the quantification of different proportions (4, 5, 6) of a fluid mixture (3).
