Abstract:
1. A method of reducing composition error in an output flow of a mixing pump system, the method comprising: actuating a first valve during a first packet to provide a first volume of a first component to an intake of the mixing pump system and subsequently actuating a second valve during the first packet to provide a first volume of the second component to the intake of the mixing pump system; and actuating the first valve for at least one subsequent packet to provide, for each subsequent packet, an additional volume of the first component to the intake of the first mixing pump system and subsequently actuating the second valve for each of the at least one subsequent packets to provide an additional volume of the second component to the intake of the mixing pump system, wherein at least two of the first and additional volumes of the first component differ and at least two of the first and additional volumes of the second component differ.
