摘要
采用节流装置的流量计量 ,其准确度会受工况的影响 ,尤其对可压缩流体将更加明显 .流量计算式中C(或α)、ε、α、β、ρ等参数变化 ,均会使结果产生误差 ,应予补偿 ,并且只有利用微处理器才可能实现在线全参数补偿 .
Accuracy of flow measurement using throttling device can be effected by variation in working state, specially for compressible fluid. In the fomular of flow calculation, variation of these paraments, for example, c (or α)?ε?α?β?ρ etc., will produce errors in the result. The compensation is necessary. On\|line all\|paramenter compensation can be done only using microprossors.\;
