ABSTRACT:
The present invention relates to an improvement in a capillary tube viscometer which includes light sensitive triggering means for timing the flow of oil between two points therein. The improvement includes optic fibers that are positioned on the tube at selected places. In addition, the tube includes impulse receiving means wherein the voltage received from start and stop positions are passed to triggering means and measuring means to translate the same into figures for manual or automatic calculation of time for the flow of oil.
