U型振动管流体密度计的设计与实现
Fluid densimeter design and implimentation based on U-type tabe vibration modet
摘要
Abstract
Harmonic oscillation of Bernoulli-Euler beam was analyzed in sense of mechanics to deduce its horizontal vibration function. The frequency function was developed with the principle vibrating function when its 2 terminals were fixed and the boundary condition was concerned. The target fluid density was ultimately solved from the density function of principle vibrating frequency. By means of the method mentioned above, a novel fluid densimeter was designed. The experiments showed that, compared with the currently applied outdoor devices, it had a higher measuring accuracy with the lower 0. 2% relative error, as well it had well performance of bad-environment resistance.关键词
