| 總結: | Flow sensing technology from today's application perspective has gained significant research interest in studying the flow sensing behavior of biomass materials over past few years. In order to facilitate the requirements of real-time flow measurement, a capacitance technique for biomass flow sensing has been developed in this research which is based on an operational amplifier based capacitive bridge circuit connected with sensing electrodes. The research objective is fulfilled via simulation and experimental validation through hardware implementation of a flow sensing set up. The experimental results have specified the measurement system which is able to sense flow variation as a change of dielectric permittivity of different biomass materials under room condition. The novelty of this research lies in the use of simple structured capacitive sensing circuit along with two different types of measuring electrodes for analyzing biomass flow sensing behavior. As a whole, this work aims to investigate and analyze biomass flow sensing behavior in order to open up a branch of research for practical implementation. |
