Abstract
There is disclosed herein a method of measuring and profiling a process liquid in a process vessel. The process liquid includes an emulsion layer between two media of differing dielectric constants. An electromagnetic signal is generated and transmitted along a probe, defining a transmission line, extending into the vessel. The transmission line comprises a conductor in contact with the process liquid with an insulating coating on the conductor to maximize signal penetration in the process liquid. A reflected signal is received from the transmission line and a programmed controller is operatively connected to the probe for measuring characteristics of reflected signal energy along the transmission line for profiling the emulsion layer.

- operating a programmed controller operatively connected to the probe for measuring characteristics of reflected signal energy along the transmission line for profiling the emulsion layer.
A method of measuring and profiling a process liquid in a process vessel, the process liquid including an emulsion layer in a high conductivity liquid, comprising:
- generating an electromagnetic signal;
- transmitting the generated electrical signal along a probe, defining a transmission line, extending into the vessel, the transmission line comprising a conductor in contact with the process liquid with an insulating coating on the conductor to maximize signal penetration in the high conductivity liquid;
- receiving a reflected signal from the transmission line;
- and
- operating a programmed controller operatively connected to the probe for measuring characteristics of reflected signal energy along the transmission line for profiling the emulsion layer.
A process measurement instrument for measuring and profiling a process liquid in a process vessel, the process liquid including an emulsion layer between two media of differing dielectric constants, comprising:
- a coaxial probe, defining a transmission line, comprising an inner conductor in an outer tube with a relatively thin insulating coating to maximize signal penetration in the process liquid;
- a controller electrically connected to the transmission line, the controller generating an electromagnetic signal on the transmission line and receiving a reflected signal from the transmission line, and measuring characteristics of reflected signal energy along the transmission line for profiling the emulsion layer.
