Abstract
An apparatus for measuring a composition of a fluid has a fluid conduit with a wall defining a fluid flow path, a transmitting antenna, a receiving antenna, and an electrically conductive waveguide member for electromagnetic coupling with the transmitting antenna and the receiving antenna and for guiding an electromagnetic field from the transmitting antenna to the receiving antenna along a waveguide path. The waveguide member is separated from the fluid flow path by an electrically insulating inner region of the wall. The waveguide member defines an opening disposed towards the fluid flow path to permit a portion of the electromagnetic field to extend through the opening and the inner region of the wall into the fluid flow path.
