摘要
在智能流量计中过热蒸汽密度计算公式基础上,采用加权最小二乘算法,重新计算了密度公式中的多项式系数,使新系数下的密度公式既适用于过热蒸汽也适用于饱和蒸汽密度的温度补偿.
On the basis of the calculation formula for density of superheat steam in intelligent flowmeters and by combining the weighted least square algorithm the polynomial coefficient in density fonnula is re - calculated. The density formula under new coefficient is suitable for the temperature compensation of the density of superheat steam and saturated steam.
