"I discussed this problem with an engineer from KOBOLD Messring company, a well-know manufacturer of flow measurement equipment. He confirmed that <b>it is not possible to measure such small quantities (ml/min) at high flow rates for very short time (e.g. 0,2 ml in less than 20ms)</b> with good accuaracy and "normal" equipment. Even their best device (3.500 Euro!) couldn't measure this."
