ABSTRACT:
A device for sampling and pumping liquids contained in a chemical reaction vessel, drum, or storage tank. A conduit is submerged in a liquid and linked to a cylinder having a piston connected by means of a semi-rigid wire to a manually-operated lever or automatic control system. At the beginning of the cycle, the piston is positioned outside of its associated cylinder, leaving sufficient space for the liquid to enter. When the piston is drawn into the cylinder, the liquid is pushed into the desired sampling container or to a chamber that contains a sensor which continuously measures the parameters of the liquid, when the system is operating cyclically.
