摘要
A method and apparatus for providing calibrated and linearized flow sensors for VAV systems with the sensor corrected for device/electronic/drift/and field air turbulence characteristics using factory calibrated flow or pressure sensors with output modified by a transfer function incorporated into a lookup table for each sensor. This allows low power processors to handle the adjustment onsite. Further adjustment is made onsite with reference to actual flow and turbulence effects.
