Abstract: Properties of a multiphase mixture flow are measured in a blind-tee. The measured properties include the permittivity and/or the conductivity of the multiphase mixture flowing through a conduit. The permittivity and/or conductivity are measured at liquid-rich region(s) in a blind-tee section of the conduit and are used to determine properties of a liquid phase of the multiphase fluid flow, including one of the water conductivity, water in liquid ratio and water volume fraction. One or more electromagnetic sensors may be used in the blind-tee to measure the permittivity and/or conductivity. The sensors may be in contact with the multiphase flow or be disposed behind a dielectric window.
