This paper presents the development research of a unique flow meter utilizing fow force. This flow meter makes use of flow force by appropriately laying out the inclined plate or tapered shaft in a flow line to generate torque. The feature of this flow meter is as follows:(1) The structure is simple.(2) The pressure loss thorough the flow meter is very small.(3) The flow rate can be instantaneously acquired by measuring torque; thus a good dynamic response can be expected. In this paper, the fundamental principle and the mathematical model of the present flow meter are described. Then as the first step of the development research, the fundamental characteristics for asteady state are investigated theoretically in order to obtain the design criterion. In addition, based on thisinformation, the dimensions of the proposed flow meter are derived as example design cases.
