摘 要:利用石油和水之间电磁性质的差别.设计出一个振荡回路,其振荡频率随含水率的变化而变化.通过电磁耦合,采用短波谐振法来检测这种变化,从而研制出一种短波型原油低含水率(0~5%)测定仪.该仪器输出的电压信号随原油含水率发生单调变化,且有很好的稳定性和重复性,由此可测出原油的含水率.An oscillatory circuit based on the difference of electromagnetic properties between oil and water was designed. The oscillatory frequency of the circuit changes with water content. The change can be measured with electromagnetic coupling and short-wave oscillatory method. A shortwave meter for measuring the low water content (0~5%) in crude oil was developed. The voltage output signal of the meter changes monotonously with the water content in crude oil, keeping good stability and repeatibility. The water content in crude oil can be determined easily with the device.
