Patent ID: 8763693

Claim:
An apparatus, comprising: a chemical injection management system for regulating a fluid flow into a wellhead, the chemical injection management system comprising: a chemical injection flow path having an inlet and an outlet; a motorized valve disposed along the chemical injection flow path between the inlet and the outlet; a non-invasive flow meter disposed about the chemical injection flow path between the inlet and the outlet, wherein the non-invasive flow meter comprises first and second transducers disposed on opposite sides about the chemical injection flow path, and the first and second transducers are oriented at an acute angle relative to a longitudinal axis of the chemical injection flow path; and a controller communicatively coupled to both the flow meter and the motorized valve, wherein the controller is configured to exercise feedback control of a parameter of fluid flow through the chemical injection flow path based on a feedback signal from the flow meter without exercising feedback control of a position of the motorized valve.
