The Utah Biomedical Test Laboratory, under a contract from the National Institute for Occupational Safety and Health, had developed a flow calibration system suitable for calibrating spirometers. This instrument produces forced air pulses from precise waveforms for selected volumes. Air is forced by a single reciprocating piston, driven by an electronic servomotor-tachometer. The piston motion is sensed by a linear variable displacement transducer, and the volume output derivative is the flow signal for the calibrator. The system has been calibrated to assure accuracy of piston placement, and the ability to deliver precise air pulses repeatedly.
