流体流量的测量中广泛使用标准节流件作为测量部件，它虽然具有被测介质范围宽、运行费用低等优点，也存在量程比小，精度不高的缺点，而且计算过程特别繁杂，给使用带来一些麻烦，本文分析产生上述缺点的原因并提出了一种新型全补偿算法，对如何求取密度、流量系统、流束膨胀系数、节流件通径等四种补偿因子的具体算法，通过生产实践证明全补偿算法可以大大提高量程比和精度，有很大的实用价值。
The measurement of fluid flow is widely used in the measurement of the standard throttle parts, although it has a wide range of measured media, low operating costs, there is also a small range, the accuracy is not high shortcomings, and the calculation process is particularly complicated, to use Bring some troubles, this paper analyzes the causes of the above shortcomings and proposes a new full compensation algorithm, on how to get the density, flow system, flow expansion coefficient, throttle diameter and other four kinds of compensation algorithm specific algorithm, Through production practice proved that the full compensation algorithm can greatly improve the range ratio and accuracy, have great practical value.
