In this paper, we proposed a method to determine the flow rate characteristic parameters directly by using an integral algorithm which is not needed to calculate the flow rate. In the isothermal discharge method discussed by ISO, the flow rate characteristics of pneumatic components can be obtained by pressure response and flow rate. The pressure response is measured in an isothermal tank and the flow rate can be given by differentiating the measured pressure response. Because of using the differential algorithm, calculation precision for measurement error and distribution is much poorer. By integrating pressure experimental result with least error method, characteristics can be obtained easily with Excel tool. Some experimental results are given to show that the proposed calculation method in this paper is more effective than the conversational method by using pressure sensors with different precision.
