Color measuring device for a fluid distribution system

A tint measuring device configured for being connected in series in a fluid flow path, the tint measuring device comprising:

• at least one light source emitting polychromatic light towards the fluid in a measurement zone;
• a light sensor receiving a light signal either reflected from or transmitted through the fluid, the reflected or the transmitted light signal corresponding to the optical reflection or to the optical transmission, respectively, by the fluid, of the polychromatic light emitted in the direction of the fluid by said at least one light source;
• a computing unit configured for performing spectral analysis of the light signal received by said light sensor and for determining a chromatic signature of the fluid;
• at least one acquisition optical fiber configured for routing the light signal either reflected from or transmitted through the fluid to said light sensor, said light sensor being remote from the measurement zone;
• at least one lighting optical fiber connected at one end to said at least one light source and configured for routing the polychromatic light from said at least one light source toward the fluid;
• an end body encapsulating the end or ends of said at least one acquisition optical fiber and the end or ends of said at least one lighting optical fiber;
• and
• an anti-reflection element arranged so as to optically isolate said at least one lighting optical fiber and said at least one acquisition optical fiber from each other, so as to limit the direct transmission of light from said at least one lighting optical fiber to said at least one acquisition optical fiber.
