The Calibration System of Gas Flow Meter Based on Standard Flow Meter Method

Abstract:

Flow meter coefficient calibration system is designed and developed by the software of LabVIEW, hardware of PCI-6601 and USB-6008 from NI. Synchronous dual timer pulse interpolation is used to increase the calibration accuration of Standard flow meter method.It’s also necessary for system to collect the real-time temperature and pressure parameters to correct gas volume. The software complied by LabVIEW realizes functions of manage and data processing, the calculation and Storage of data, inverter control, report, data playback, and interactive interface. Results of experiments show that: compared to the routine standard flow meter method, the System has the more calibration accuracy and the less work time.
