Abstract：In order to solve the problem of measuring the flow rate in microtubes（the hydraulic diameter is under 1mm）,the Micro-PIV is used to measure the flowrate within the capillary tube,and its hydraulic diameter is 230μm. In the experiment,the flowrate is measured in the reynolds number range of 480~2260,and the conclusion is that Micro-PIV technique can be used to measure the flowrate in the microtubes with high precision.
