Abstract
A device for determining the mean resistivity of a multiphase fluid having a continuous conductive phase, includes a pipe segment () of insulating material and a oil () for generating an electric current in the fluid flowing along the pipe. The device has two measurement electrodes () spaced apart in the axial direction of the insulating segment to measure the electrical resistance between said two electrodes, the measurement electrodes being applied to the outside of the wall of the segment to perform measurement by capacitive coupling. The voltage between the measurement electrodes is measured. The device is particularly useful for determining the volume fraction ('holdup') of water in a mixture of water and hydrocarbons.
