摘要： A method of and apparatus for measuring or measuring-out a predetermined volume of a liquid flowing through a conduit or line, comprising a first conduit section containing a measurement path and at one end connected with the outlet conduit of a connection element which interconnects a first inlet conduit and a second inlet conduit. The first conduit section is operatively connected at its other end through the agency of a first valve with the low pressure side of a pump device. The first inlet conduit is continuously connected with a liquid container via a second conduit section which causes a dynamic pressure drop in the flowing liquid. Additionally, the second inlet conduit is continuously connected with a fluid container and the fluid container is connected via a second valve with a compartment, whereas the liquid container is continuously connected with the compartment and the high pressure side of the pump device opens into said compartment.
