The limitation of conventional pitometer are as follows: the frequency response is very low, the error margin is big especially for liquid.It is difficult to dispel air in pipe before measuring or in middle of measuring,it is difficult to eliminate influence of result.Due to these,Shuangqiao company designed CYG9008 type dynamic state pitometer according to the principle of pitot tube,playing a technological advantage in researching miniature high frequency dynamic pressure sensor,the frequency response of this type productionis 150 Hz, the most high-precision of flow rate is 0.3%,the flow rate measuring range is from 0 m/s to 10 m/s, automatic calculation of flow rate,automatic acquisition, storage. So it can improved the accuracy and efficiency.
