ABSTRACT:
An apparatus provides for the addition of a predetermined amount of a second liquid (metering liquid) to a first liquid contained in a vessel, with a predetermined final fill level of the vessel being attained. By introducing a pressurizing gas into the vessel an amount of the first liquid is forced out of the vessel through a riser tube until the liquid level reaches a first opening in the tube to cause the expulsion of the first liquid to cease. The predetermined amount of the second liquid is then introduced in the vessel. Some of the first liquid is then returned to the vessel while expelling gas from a second opening in the tube until the liquid level covers such second opening to cause the further introduction of first liquid to cease. Thus, the desired final fill level is automatically obtained.
