According to this, conducting liquid level can be gauged by measuring the conductance of the liquid with a pair of electrodes and this method has been proved to have a relative high-accuracy.

根据这一原理，可利用电极测量导电液体的电导来获得液位，此方法对于导电液体液位的可接触式测量能够得到较高的测量准确度。

The iGlassware system works by coating each glass with a clear, conducting material, enabling it to measure exactly how much liquid has been sipped or guzzled.

这种智能酒杯的工作原理是给酒杯涂上一层光洁的传导材料，这样无论顾客是小啜还是狂饮，这套系统都可以测量出酒杯中还剩下多少酒。
