摘　　要：针对目前普遍应用的定量称重衡器大多不能满足高准确度定量称重的要求,设计了一种全新的基于浮力称量原理的定量称量系统。该系统采用自行研制的浮力平衡器取代了电子衡器的核心器件(称重测力敏感元件)。浮力平衡器是基于液体的浮力原理将物料重量值的测量转换成具有线性关系的位移值测量的称重核心装置。文中详细论述了该系统的工作原理及硬件和软件的设计与开发。最后给出了该系统的动态称重试验结果及结论。Considering the commonly used strain gauge load cell can not mostly satisfy the requirements on performance for Quantitative weighing of high degree of accuracy, a quantitative weighing system of whole quantity based on the principle of buoyan- cy was designed. This system utilized for the first time the buoyancy principle of liquid to change the measurement of the weight value of materials into a buoyancy equalizer of measurement of the displacement value with a linear relation, and took the place of the key element of electronic weighing instrument technology, which uses sensitive element of strength. The operation principle of the system and the design of its hardware and software were described in detail. The test result and expert＇s conclusion on this sys- tem presented.
