Abstract
Steam quality is measured by mixing the steam with a small amount of surfactant to convert the steam to a stable foam, passing the stable foam through a capillary tube to determine foam quality (volume of vapor per volume of vapor and liquid) by measuring the streaming potential coupling coefficient of the foam passing through the tube, and converting foam quality (volume per volume) to steam quality (mass of vapor per mass of vapor and liquid) based upon the fluid density of the liquid-water and water-vapor phase of the steam.
