Abstract
A method of correcting fluid flow offset for an uncharacterized fluid handling system including a motor. The method includes running the motor at a reference fluid flow demand using generic coefficients, and changing fluid flow demand from the reference fluid flow demand until the motor signals a power limit condition. When the motor signals the power limit condition, the fluid flow demand is noted. The operational fluid flow demands are scaled by a ratio of the noted fluid flow demand to the reference fluid flow demand.
