ABSTRACT:
A method for determining any fluid mixture composition and for measuring material quantity by detecting light absorption, especially infrared light, emitted by an emitter (12.1, 12.2) in a fluid to be analyzed having non absorbed and non reflected components that are detected by a receptor (18.1, 18.2). According to said method, light is emitted directly from the emitter (12.1, 12.2) to the receptor (18.1, 18.2) through said fluid. Additionally, the light going through a channel (10, 16) before and/or after the fluid is dispersed at least once. The distance between emitter (12.1, 12.2) and receptor (18.1, 18.2) can be continuously altered. Electronic components are provided with a switch enabling to remove any interference light.
