ABSTRACT:
A liquid mixing system and method are disclosed for automatically preparing a batch mixture containing predetermined quantities of liquids such as spray dampening solutions or silicone emulsions used in the printing industry. The system comprises a holding tank having one or more liquid columns in liquid communication with the tank so that the level of liquid in the column, or columns, will be the same as the level of the liquid in the tank. Liquid level detection devices preferably in the form of static capacity-type proximity switches sense the level of the liquid in the column, or columns, and liquid charging devices responsive to the liquid level detection devices charges the liquids into the tank in seriatum each time raising the level of the liquid in the tank and in the columns to the next detected level. The tank liquids are mixed preferrably by an external mixing device which also operates to discharge the liquid mixture from the tank through a three-way valve operating in response to the liquid detection devices.
