Abstract
A method of controlling a flow rate includes selecting an operating condition defined by an operating flow rate and an operating pressure, comparing the operating flow rate to a threshold flow rate, and executing an adaptive calibration routing if the operating flow rate is greater than or equal to the threshold flow rate. The adaptive calibration routine includes measuring the operating pressure, measuring a first flow rate through a first meter, and modifying a pressure-flow table based on the operating pressure and the first flow rate.
Claims11
A method of controlling a flow rate includes:
- selecting an operating condition defined by a flow rate set point and a pressure set point;
- comparing the flow rate set point to a threshold flow rate;
- executing an adaptive calibration routine if the flow rate set point is greater than or equal to the threshold flow rate, wherein the adaptive calibration routine includes:
- measuring an operating pressure;
- measuring a first flow rate through a first meter;
- storing the operating pressure and the first flow rate;
- modifying a pressure-flow table based on the operating pressure and the first flow rate;
- and
- causing the first meter to operate at the first flow rate.
