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 ...

Abstract

This invention relates to a liquid concentration test method and a device including the following steps: 1, putting a reflection mirror in the solution with unknown concentration, 2, plugging the emit fiber in the liquid in an acute angle with the reflection mirror to let the end face of the fiber parallel to the mirror, 3, designing a receiving fiber on the beam reflection direction of the emit fiber, 4, injecting a defined strength beam by emitting the fiber, 5, collecting reflection beams by receiving fibers, 6, designing a photoelectric tube at the outlet of the receiving fiber to compute the liquid concentration with the strong or weak signals of the conversion of the tube.

Description

technical field [0001] The invention belongs to the technical field of measurement and control, and in particular relates to a method for measuring liquid concentration and also relates to a measuring device for the liquid concentration. Background technique [0002] At present, the existing various sensing devices cannot be used to measure the concentration of gases and liquids, and the existing methods of measuring the concentrations of gases and liquids mostly use chemical analysis methods, which are inefficient and not intuitive enough, and are not easy to realize automatic control. Contents of the invention [0003] The object of the present invention is to provide a method for measuring liquid concentration. [0004] At the same time, the object of the present invention is to provide a liquid concentration measuring device. [0005] In order to achieve the above object, the technical solution of the present invention is to adopt a kind of liquid concentration measu...
