1. A fluid metering device, comprising
at least one processor; and
at least one memory that that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
receiving position data indicative of an orientation of a damper having a variable aperture that varies based on the orientation;
receiving pressure data determined from at least two pressure measuring devices comprising a first pressure measuring device that is situated at a first location that does not change based on the orientation of the damper and a second pressure measuring device that is situated at a second location that does not change based on the orientation of the damper;
based on the position data and the pressure data, performing a calibration procedure that determines at least two pressure differentials comprising a first pressure differential that results from a first orientation of the damper and a second pressure differential that results from a second orientation of the damper; and
performing a controlling procedure that, based on the at least two pressure differentials, determines a target orientation of the damper to satisfy a set point based on a pressure differential at the target orientation.
