ABSTRACT:
A waveguide and pressure barrier for use with devices for measuring fluid parameters of fluids passing in a pipe under high temperature and pressure conditions and utilizing microwave energy for making the measurements, the device including a pair of substantially identical members adapted to be mounted in spaced opposition on the pipe. Each member has an axial bore with a transverse bore for receiving a microwave antenna. The axial bore is substantially filled with a ceramic glass material providing the pressure and temperature barrier.
