Abstract:
Online/remote calibration is the transformation and expansion of traditional measurement. Its development will play a certain role in strengthening measurement management, improving the overall strength and level of measurement, and promoting trade and economic development. In this paper, a set of on-line/remote detection standard devices with a flow range of (0.4 ~ 400) m³/h, expanded uncertainty: U ≤ 0.33 %, k = 2 was designed and developed. Rely on the Internet + calibration mode, use the wireless Internet to send signals from the laboratory to the standard testing module, establish a remote service to send remote control commands, monitor the physical and electrical connections, and control the standard testing module. The program controls the calibration process automatically complete online /remote calibration.
