A fluid integrating system (10) includes an integrating manifold (30) having two or more input fluid inlets (132) disposed at oblique angles relative to a center axis of the integrating manifold (30). The two or more input fluid inlets (132) intersect in the integrating manifold (30) to define an integrating chamber (112). The fluid integrating system also includes a pressure sensor (110) fluidly connected to the integrating chamber (112) that is operable to send a pressure signal indicative of the pressure of the fluid in the integrating chamber (112). A integrating controller (22) is operatively coupled to the two or more valves (60) and to the pressure sensor (110) and is operable to selectively control the flow of input fluids into the integrating chamber (112) by actuating the two or more valves (60) based on the pressure signal received from the pressure sensor (110).
