流量计动态特性的研究乃是一个特别难以解决的问题,这是由被测的量的物理性质决定的。流量计的动态特性不仅取决于计量器具本身的性能,而且还取决于一次变换器与液漪相互作用的特点。液流的流体动力学图形在非定常流动状态下是相当复杂的。
The study of the dynamics of a flowmeter is a particularly difficult problem to solve, as determined by the physical properties of the quantity being measured. The dynamics of a flowmeter depend not only on the performance of the measuring instrument itself, but also on the characteristics of the primary interaction between the transducer and the fluid. The hydrodynamics of a fluid flow are quite complex under unsteady flow conditions.
