摘要
介绍了采用电磁波复谐振技术测量液体相对介电常数的原理和方法,讨论了水的矿化度和有机物含量对水溶液相对介电常数的影响以及对电容传感器测量原油含水率结果的影响。当含水率低时,可以不考虑水相对介电常数的变化对电容传感器测量原油含水率结果的影响,但在高含水率时期,必须考虑水相对介电常数的变化所产生的测量误差。
This article introduces a method for measuring the liquid permittivity using electric magnetic wave harmonic. The water salinity and organic matter in water can effect the liquid permittivity and the water cut measuring results using the capacitive sensor. The influence for measuring the water cut by the changing of liquid permittivity can not be taken into account in the low water cut,but the measuring difference induced by the changing of the liquid permittivity must be considered.
