Liquid level measurement arrangement - contains flat strip cable with parallel illuminating and conducting cable pairs detecting liquid presence at corresp. levels

摘要

Illumination cables at different levels pass light to corresp. light conducting cables when no liquid is present between them. No light passes between a pair of cables if liquid is present between them. The normal components of the light input and output surfaces respectively of the illuminating and conducting cables face in The cable pairs (2.2.1, 2.2.6) longitudinal direction. are in flat strip cable form (2.3) at fixed distances, parallel and at an angle to the liquid surface. USE/ADVANTAGE - Can be used to measure levels of liquids of any surface tension and refractive index of vehicle fuel tank.
