Measure principle of difference-pressure bend flowmeter was analyzed, the theoretical flux formula were calculated. Flow characteristic was simulated based on fluent software, the distributing laws of pressure, flow and secondary flow were studied, and how to select the best measurement section was discussed. The simulation result was consistent with the practice, and it is help-ful for structure optimization of flowmeter.
