ABSTRACT:
Inlet conduits supply different liquids under pressure to a measuring unit which delivers measured quantities of the respective liquids to a common outlet conduit for the desired liquid mixture. To counteract variations in the flow rate of the mixture in the outlet conduit due to operation of the measuring unit, the inlet conduit for one of the liquids and the outlet conduit for the liquid mixture are connected to respective chambers containing a movable dividing member subjected to opposing pressures in the two chambers. When the flow rate decreases in the outlet conduit, the resulting pressure drop in the outlet chamber connected to this conduit causes the constant pressure in the other chamber to move the dividing member into the outlet chamber and thereby expel liquid mixture therefrom so as to compensate for the decreased flow rate in the outlet conduit.
