In order to meet the requirements for the detection of flammable and explosive continuous liquid level, based on the principle of static liquid pressure, we developed a liquid sensor by using optical fibre Fabry-Perot cavity interferometer.
为了适应易燃易爆液位检测的需求,我们利用液体压力测量液位的原理,提出一种光纤法布里-珀罗(F-P)腔连续型液位传感器。
Before the intense earthquakes occurred in Haicheng, Tangshan, Bohai etc, the deep oil-water wells of Shengli oilfield showed anomalies, such as Liquid production, oil production, static pressure in oil wells and water Level etc.
渤海、海城、唐山等强烈地震前,胜利油田油水深井动态有明显异常显示,主要表现在油井产液量、产油量、静压、水井水位等动态参数的变化上;
