Abstract
A radar transmitter for emulsion measurement comprises a probe defining a transmission line for sensing impedance. A pulse circuit is connected to the probe for generating pulses on the transmission line and receiving a reflected signal from the transmission line. The reflected signal comprises a waveform of probe impedance over time. A controller is operatively connected to the pulse circuit. The controller profiles content of the emulsion responsive to the waveform by transforming the waveform into impedance relative to distance, converting the transformed waveform into effective dielectric relative to distance, determining mixture content of the emulsion at select distances responsive to the effective dielectric at the select distances and developing an output representing mixture content relative to level units.
