Abstract
An apparatus includes a transmitter configured to transmit a signal having an electromagnetic pulse towards material in a tank. The apparatus also includes a receiver configured to receive a signal having multiple reflections of the pulse, including a process connector reflection. The apparatus further includes at least one processing device configured to determine a measurement associated with the material in the tank based on the received signal. To determine the measurement, the at least one processing device is configured to identify the process connector reflection in the received signal using an asymmetrical model. The transmitter, the receiver, and the at least one processing device could form at least part of an electronics assembly, and a connecting cable could couple the electronics assembly and a process connector. The asymmetrical model could have different lobes of different shapes.
