A Dynamic Measurement of Flow Rate for Unsteady Gas Flow

摘要：

In this paper after current situation of gas flow rate measurements is reviewed, a dynamic method for measuring unsteady flow, in which flow rate of gas can be dynamically measured, is proposed based on theory of linear approximation. The measurement results are compared with that of the traditional method using pressure loss in the pipe, and its dynamic error is less. The new method is very convenient to use so that it may have a wider industrial application for saving energy and controlling flow rate in the future.
