Abstract

To achieve portable metrological calibration for a micro gas flow meter， a micro gas flow calibration facility was devised using the piston prover method. The geometric dimensions of the piston were determined through mathematical modeling. Additionally， a photoelectric detection system based on fiber optic sensors was constructed to meet the required detection time accuracy of the device. The dynamic grid 6DOF technique was utilized to study the positions of the fiber optic sensors， analyzing inertial effects during piston motion to ensure uniform movement between the two fiber optic sensors. To meet the needs of on-site on-line calibration intelligent system， a PLC-based control system was developed， accompanied by a human-machine interaction control and data acquisition interface. An uncertainty analysis and assessment of the device were conducted， resulting in an extended uncertainty of 0.38% （k=2）.
