Abstract: A system and method is disclosed for permitting a chemical fluid line to serve multiple downstream injection sites from a single upstream pump. One or more redundant primary chemical conduits are manifolded via a flexible joint into a plurality of sub-stream chemical conduits, each of the sub-stream chemical conduits comprising a sub-stream flow meter and an independently controlled motorized flow control valve. A control computer directs each respective flow control valve to open and close depending on the desired flow rate of the respective downstream injection site.
