Division of Thermophysics and Process Measurements

Overview

Flow Lab is in charge of establishing and disseminating measurement standards and providing calibration services for flow rate, flow velocity measurement and R&D of related measuring technologies. At present, we have National Standard Equipment for gas flow rate and water flow rate measurement which can provide relevant calibration services with highest accuracy and reliability. We are also carrying out R&D works in order to expand...

  • Facility Establishment for Hot Water Flow Measurement

    A new hot water flow facility is being built. Its flow rate range is (0.03~600) m3/h, and its temperature range is (5~90)℃. This project will be completed at the end of year 2012. The diameter range of this facility is from DN 6 to DN 250. The...

  • Establishment of Air Velocity Reference Facility

    The air velocity reference facility is composed of a wind tunnel with 200mm outlet and a 3-D LDA. The velocity range is from 0.2m/s~30m/s with an expanded uncertainty of velocity expected to be 0.3% (depends on the calibration result of LDA...
