- Abstract:
- The mathematical model and the measurement uncertainty of the outflow coefficient for calibrating the sonicnozzle with the High Pressure Piston Prover (HPPP) primary standard device were studied. The design and modification of the existing HPPP primary flow standard device were carried out. , replace the upstream transmission turbine flowmeter with an ultrasonic flowmeter, and replace the downstream transmission turbineflowmeter with a set of inspected sonic nozzle pipe sections, optimize the uncertainty of the measurement results, and realize the function of calibrating the sonic nozzle with the HPPP primary standard device.
