Abstract
In gas–liquid flows through test loops, the fluid temperature increases, causing a change in the dielectric properties, mainly of the liquid component, which interferes with the response of capacitive void fraction meters. This phenomenon causes, for example, deviations of about 4% in the meter response for each 10 ∘C variation of temperature in the air–water flow. In this work, a simple procedure is proposed for correcting for the response of capacitive void fraction meters being affected due to the flow temperature being different from the calibration temperature. Static and dynamic tests were performed on a capacitive void fraction measuring system with double-helix electrodes. The results showed the effectiveness of the proposed compensation technique, which allowed a significant reduction of the measurement deviations.
