A device for transmitting predetermined volumes of liquid from one container to another container consists of a pipe leading from the first container to the second container and immersed into the liquid in the first container, means sealing the first container, a pressure transmitting tube introduced into the first container for producing pressure means pressing the liquid through the pipe and means measuring a predetermined liquid volume. The invention is particularly characterized in that there is a substantially constant super pressure in the first container and there are two signalling devices spaced from each other and located in the path of the flowing liquid. When the liquid front passes them they transmit a signal to a calculator which determines from these signals the volume of liquid passing through the pipe per time unit. Closure means for the liquid are connected to the calculator. They receive a closing signal formed by the incoming signals after the passing of time required for the transmission of desired liquid volume set at the calculator.
