Journal ArticleDOI
Realization of a multipath ultrasonic gas flowmeter based on transit-time technique.
Qiang Chen,Weihua Li,Jiangtao Wu +2 more
TL;DR: The two paths flowmeter has been calibrated and validated on the test facilities for air flow in Shaanxi Institute of Measurement & Testing, and develops timing modules to determine the flight time of the acoustic signal.
Journal ArticleDOI
Double threshold ultrasonic distance measurement technique and its application
Weihua Li,Qiang Chen,Jiangtao Wu +2 more
TL;DR: The double threshold method realized by hardware circuits and high performance timing chip TDC-GP21 was successfully adapted to solve the key problem of ultrasonic distance measurement, the accurate time-of-flight (TOF) measurement of ultrasonic wave.
Journal ArticleDOI
Isobaric heat capacity measurements of liquid HFE-7200 and HFE-7500 from 245 to 353 K at pressures up to 15 MPa
TL;DR: An adiabatic flow calorimeter was developed for the measurement of the isobaric heat capacity of pure liquids and their mixtures, which could be used over the temperature range of (243-393) K and at pressure up to 20MPa.
Journal ArticleDOI
Research on the inherent error of ultrasonic flowmeter in non-ideal hydrogen flow fields
Qiang Chen,Jiangtao Wu +1 more
TL;DR: In this article, the inherent error of the ultrasonic flowmeter in the non-ideal hydrogen gas flow was investigated with different integrations and acoustic paths, and the results showed that the errors become larger when the flowmeter position is closer to the disturbance sources.
