| Abstract: | A new approach to measure digitally the gas volume fraction is described,and the working principle and the linearization method of scale equation are analyzed.In the course of design,it is found that the dispersity of gas sensor will affect greatly the measurement result of gas volume fraction.Hence,the measurement error caused by the influence of the gas sensor dispersity on the measurement result of the gas volume fraction is analyzed,and the measurement accuracy of ensuring the gas volume fraction is discussed,also the selection requirement and method of gas sensor are given. An example is successfully introduced to verify this analysis method. |
