Study on the model of dynamical different pressure flow meter & optimizing of parameter

A new method to measure dynamic flow was introduced, using the different pressure signal and temperature signal sensed from the main pipe of the flow meter body, the dynamic flow signal could be calculated. According the the laminar flow theory, the dynamic flow would be the weighted accumulate of all the different pressure value sampled during a special period. And a special optimizing program is designed to improve the calculation precision. The test result proved that this dynamical different pressure flow meter has a dynamic and static capability.
