Abstract: In order to measure the concentration of mixed oil transported in pipeline more precisely, the conductivity probe is modified and applied to determin concentration of mix oil in the pipeline based on the principle of the conductance measurement of gas-liquid two-phase flow's liquid holdup. The experimental apparatus can be used to calibrate the probe by measuring the different concentration of brine to obtain the corresponding output signal. The calibrated experimental apparatus can easily measure the concentration of mixed oil at different times and different positions of the pipeline cross section.

摘要：         为了更好地测量管道顺序输送时的混油浓度变化,基于电导探针测量气液两相流持液率的原理,将电导探针改进并将其应用到管道混油浓度的检测中。利用改进后的实验装置,通过电导探针测量不同浓度的盐水得到对应输出信号,从而得到混合段的浓度变化情况。并对探针进行了标定实验,得到不同浓度下盐水浓度与输出信号的函数关系,以便将标定后的实验装置用于测量混油段在不同时刻和管道截面不同位置的混油浓度。
