Problems solved by technology

[0015] Although the above-mentioned sensor for measuring liquid concentration can measure urea concentration, this device cannot eliminate factors that affect measurement accuracy and stability during the measurement process, for example, turbulent flow during the measurement process and impact due to turbulent flow, added liquid, etc. The air bubbles brought by it; the scale formed by the long-term settlement of the liquid on the exit surface and the entrance surface
Because the bubbles will directly affect the direction of the light path and the scattering of light, and the formation of scale will cause the formation of a halo when the light exits to the end point, and both scattering and halo will cause inaccurate measurement
In this way, the urea solution concentration measurement result obtained by the above scheme has low precision and low reliability

Abstract

The invention discloses a turbulence prevention device and scale reduction device for an optical liquid concentration sensor. The turbulence prevention device and scale reduction device comprise an outer column ring, an inner column ring, a head cover, an incident plane, a reflecting surface and an emergent surface. The invention further discloses an optical liquid concentration test device comprising the turbulence prevention device and the scale reduction device. Through providing a relatively static environment, bubbles in a tested solution can be reduced, dredged and released to the maximum extent, and the test reliability is improved. According to a scale reduction structure of an optical component of the optical liquid concentration sensor device, scales on the emergent surface and the incident plane of the sensor caused by long-term use, impurity precipitation and electrostatic interaction are guided and deposition of the scales on the effective area parts of the emergent surface and the incident plane is delayed as far as possible, so that halo formation is avoided and the detection accuracy of the sensor is improved. In addition, through providing the optical liquid concentration test device, a main body of the sensor is effectively protected, the service life is prolonged, and meanwhile, the accuracy is improved.
