Abstract:
The piston type micro liquid flow standard device is a kind of flow standard device with volume-time method. Because it can easily obtain micro flow due to its working principle, this kind of standard device is widely used in micro flowrate value traceability. In addition, the rapid development of precision machining technology also makes the processing of the piston, the master standard in the piston flow standard device, more and more precise, which plays a significant role in reducing the uncertainty of the whole standard device. In this paper, the simplified geometric model of the piston type micro liquid flow standard device is established by using modeling software, the geometric model is meshed, and finally the grid is solved to obtain the internal flow field of this type of flow standard device.
