ABSTRACT:
A device for accurately monitoring the flow and flow rate of liquids that are released slowly so as to form drops. The drops fall from the tip of a drop funnel 13 onto a surface of liquid at the top of a reaction cell 16. Consequently, the height through which each drop falls is constant. The liquid volume of each drop is measured and the flow and flow rate are calculated by transducer 19 and flow meter processing electronics 22.
