Volume charge density measuring system

摘要: A capacitive sensor includes one or more chambers through which a material can flow. Two conductors are located to partially surround the flow chamber so that flows between conductors. Where than is used, additional provided. measurement circuit connected provides an output corresponding difference test and reference frequencies. display indicates measured capacitance as continuous-scale, proportional representation binary representation. The system measure volume charge density of fluid parameters responsive changes in density, such velocity.
