Embodiment Construction
[0015] Liquid concentration measuring method of the present invention comprises the steps:
[0016] (1) Place a mirror in the liquid of unknown concentration;
[0017] (2) Insert an emitting fiber that forms an acute angle with the reflective mirror into the liquid so that the end face of the emitting fiber is parallel to the mirror;
[0018] (3) A receiving optical fiber is arranged in the reflection direction of the emitting optical fiber beam;
[0019] (4) injecting a light beam with a set intensity through the launching fiber;
[0020] (5) collecting reflected light beam through receiving optical fiber;
[0021] (6) A photoelectric cell is arranged at the outlet of the receiving optical fiber, and the value of the liquid concentration is calculated by the intensity of the light signal converted by the photoelectric cell.
[0022] Such as figure 1 As shown, the measuring device of the liquid concentration of the present invention is made up of the mirror 4 installed in ...
