The principles and operation methods of impellers rev calculation of counter-rotating fan by measuring the frequency of the pressure in the tip of the impeller blade was elaborated.A hardware platform for testing two impellers rev was built,and the automated testing software was developed based on LabVIEW.The tip pressure pulse signal of two impellers could be acquired,displayed and processed automatically.The automatic calculation,display and the generation of test report was realized by this testing system.The experiments showed that this system was easy to use,and the results were accurate.
