文提出了一种采用电容传感器测量气固两相流质量流量的新方法。通过电容传感器对固相浓度的测量,可以求出气固两相流的固气比,结合气固混合之前所测得的载气流量,便可测出固相的质量流量。实测结果显示,测量误差小于5 This paper presents a new method of measuring the mass flow of gas-solid two-phase flow by capacitive sensor. By measuring the solid-phase concentration by the capacitance sensor, the solid-gas ratio of the gas-solid two-phase flow can be obtained. The mass flow of the solid phase can be measured by combining the gas flow measured before the gas-solid mixing. Measured results show that the measurement error is less than 5
