摘要
首先经过理论分析和数据处理,得到计算蒸汽流量中的各参数简单而精确的公式;参数包括比容、流束膨胀系数、流量系数和直径比。然后使用这些补偿公式用MCS—96系列单片机中的8098研制成智能流量计。经模拟实验证明,该流量计在大的测量范围内具有高的精确度和高的可靠的性能。
At first, the simple and exact compensation formulae of parameters in steam flow calculation through theoretical analysis and date processing are obtained in this paper. The parameters include specific volume γ, the flow expansion coefficient ε, the flow coefficient α and the ratio of diameter β. Then, using these compensation formulae, the intelligent flowmeter is made with advanced single chip microprocessor 8098 in series of MCS—96. The simulation tests proved that this flowmeter posses the behaviour of high accurancy and high reliability in wide measurement range.
