Abstract
A probe defining a transmission line is used with a measurement instrument including a pulse circuit connected to the probe for generating pulses on the transmission line and receiving reflected pulses on the transmission line. The probe comprises an adapter for mounting to a process vessel. A conductive outer sleeve is secured to the adapter. A center conductor is coaxial with the outer sleeve for conducting the pulses. The conductive outer sleeve has a connector end proximate the adapter and a distal end to extend into a processed liquid. The outer sleeve has a geometric discontinuity defining a referenced target producing an impedance change at a position between the adapter and the distal end at a location in a process vapor region above a processed liquid.
