设计了一套微型光纤颗粒浓度测量仪，并应用于自来水中均匀颗粒浓度的测量，建立了统一的测量公式。通过测量38-250 μm范围内6种均匀碳化硅颗粒的浓度，提出了颗粒尺寸、颗粒浓度与光散射强度之间的统一关系。通过对其它三种尺寸碳化硅颗粒浓度的测量，验证了统一表达式的正确性。结果表明，测量误差小于10%，考虑到0-50 kg/m3的大测量范围，统一表达式是令人满意的。根据150 μm碳化硅颗粒在三种不同光强下的浓度测量结果，讨论了光强对浓度测量的影响。结果表明，低光强可用于高浓度测量，但精度较低;高光强可用于低浓度测量，但精度较高。
A set of miniature optical fiber particle concentration measuring instruments is designed and applied to develop a unified expression for the concentration measurement of uniform particles in tap water. By measuring the concentrations of six uniform silicon carbide particles in the size range of 38–250 μm, the unified relationship between particle size, particle concentration, and optical scattering intensity is proposed. The unified expression is verified by the concentration measurements of silicon carbide particles with three other sizes. The results show that the measurement error is less than 10%, and the unified expression is satisfactory considering the large measuring range of 0–50 kg/m3. The effects of light intensity on the concentration measurement are discussed based on the results of 150 μm silicon carbide particles under three different light intensities. It is shown that a low light intensity can be applied for high-concentration measurement with relatively low accuracy, while a high light intensity can be adopted for low-concentration measurement with higher accuracy.
