The invention relates to a flow velocity detector and system based on noble metal circular dichroism, and mainly relates to the field of flow velocity detection. According to the flow velocity detector based on noble metal circular dichroism provided by the invention, the flow velocity detector comprises a substrate and a plurality of detection parts, the plurality of detection parts are periodically arranged on one side of the substrate, and each detection part comprises a supporting part, an elastic column and a deflection part; the supporting part is arranged on one side of the substrate; the elastic column is perpendicular to the supporting part; the deflection part is arranged at the other end of the elastic column away from the support part; when the flow velocity to be measured needs to be measured, the flow velocity detector is put into an environment to be detected; due to the fact that the elastic column has certain elasticity, flowing of the environment to be detected drivesthe deflection part to deflect, the deflection part deflects to enable coupling between the deflection part and the supporting part to be changed, then the circular dichroism of the detection part ischanged, and the accurate flow rate to be detected is obtained according to the relation between the change of the circular dichroism and the flow rate.
Description
technical field [0001] The invention relates to the field of flow velocity detection, and mainly relates to a flow velocity detector and system based on noble metal circular dichroism. Background technique [0002] Velocity refers to the distance traveled by a gas or liquid flow particle in unit time. The flow velocity at each point of the water flow in the channel and the river course is different. The flow velocity near the bottom of the river (canal) and the riverside is relatively small, and the flow velocity near the water surface in the center of the river is the largest. For the sake of simplicity, the average velocity of the cross section is usually used Indicates the velocity of the water flow in the section. [0003] In the prior art, the method of detecting the flow velocity is mainly to detect the flow within a certain period of time, calculate the ratio of the flow to time, and use the ratio of the flow to time as the flow velocity to be measured. [0004] How...
