Abstract
A method for measuring flow rate based on dynamic optimization of three pressure sensors is provided. In the method, pressure sensors are set on the fix positions of both ends of the test straight pipe and on the middle position of the test straight pipe, and are configured to measure the pressure of the fluid at the positions where the pressure sensors are set in real time, and the real-time dynamic flow rate of the fluid in the pipe can be estimated through a flow rate calculation estimator. The method has fast response speed and high measurement accuracy, can effectively eliminate the noise interference of vibration in the environment, and has strong anti-interference ability.
