Abstract
In this paper we propose an approach of unsteady flow rate measurement by using a drag-plate-type drag force flowmeter (DPFM). This type flowmeter has not been used as an unsteady flow rate sensor because the dynamic characteristics of this type flowmeter are not well known. In this study, we aim to realize an unsteady flow rate measurement with fast response and without expense. In this paper, we propose a simplified mathematical modelling of the DPFM, and real time unsteady flow rate measurement method using the dynamic modelling. As a calibration method, we employ cylindrical-choke-type instantaneous flowmeter (CCFM) and remote instantaneous flow rate measurement (RIFM). It is shown experimentally that the proposed unsteady flow rate measurement method is valid. Obtained results are as follows. As comparing the flow rate of the DPFM with that of the RIFM, first, the gain and phase characteristics of the DPFM show a good agreement within 1 dB and 10° with the RIFM over frequency range of 100 Hz, secondly, the DPFM demonstrates sufficient accuracy up to frequency of 400 Hz that is a resonant frequency of the beam system.
