ABSTRACT:
The fluid proportioning and mixing unit includes a metering and pumping section and a mixer unit. The metering and pumping section is divided into a first solute section and a second section exclusively used for the conduction of motive fluid. At least two metering units extend between the first and second sections and operate to draw solute in through the first section and expel measured volumes of solute back into the first section. Simultaneously, the metering units receive motive fluid from the second section and expel motive fluid back into the second section. The expelled motive fluid is directed to an equalizer system which provides lift height compensation for the solute supply. A mixer unit receives measured volumes of solute from the first solute section and incorporates a ratio valve assembly to mix this solute with a base fluid in a variable preset ratio which is maintained by the ratio valve assembly.
