Abstract

The parameter measurement of gas-liquid two-phase flow has important industrial applications and scientific research significance. In order to realize the measurement of gas-liquid two-phase flow parameters, this paper designs a sensor for capacitively coupled contactless conductivity detection (C⁴D) based on series resonance technology. Through the analysis and design of the sensor structure, it is not only possible to combine the designed sensor shielding structure, which can weaken the influence of external interference signals; it is also possible to eliminate the influence of capacitive resistance in the measurement through the series resonance technique; and its input and output characteristics are monotonic, which facilitates the measurement of parameters. In order to verify the theoretical linearity of the input and output characteristics of the dual inductance sensor, conductivity measurement experiments were carried out to obtain the result that the sensor is monotonic in input and output characteristics, but not linear in practice. After the demonstration and experiments, the results show that the developed dual inductance sensor validates well and meets the requirements of the detection.
