Abstract
Precalibrated flow meters which include electronic modules that contain, in a storage memory thereof, a plurality of calibration factors that correspond to a plurality of different fluids. The calibration factors can be chosen during field operations using a touch pad on the face of the meters. The precalibrated flow meters monitor current and accumulative totals of fluid volumes. The precalibrated flow meters can be used in conjunction with air flow compensators which sense the flow of air through a fluid flow passage.
