This paper describes experimental studies about an entirely new device for measuring flowrate (called Dynamic Flowmeter) which provides precise direct digital output proportional to the flowrate. A cylindrically winding strip supported on a frame is installed on an orifice in the flow. The differential pressure in the orifice acting on the strip causes a deflection. Thus, when the deflection can be measured accuratily, this flowmeter operates as precision linear instrument with high reproducibility. The principal characteristics of the flowmeter are analized by using a simplified flow model. To evaluate the performance, experiments for air and within the range of the flowrate (0∼8.3×10-4[m3/s]) are conducted. The flowmeter constructed with suitable parameters is promising for practical applications.
