摘要
本文的研究目的是要提出一个新的瞬态流量的测定方法。我们根据从差压信号推算流量的原理,试制了一个非定常流量计。实验证明,这种流量计不仅结构非常简单、实用,而且对非定常流量的测定具有较高的精度。
The purpose of the work reported in this paper is to establish a new method for measuring instantaneous flow rate. On the basis of a measurement principle transforming' differential pressure into the flow rate, a flowmeter is made on trial. It is clarified by experiments that the flowmeter used for measuring unsteady flow is not only simple but also precise and practical.
