A method for detecting the presence of a twin peak pulse in a waveform, generated by a microwave level transmitter, that is used to detect levels of first and second material interfaces relating to materials contained in a tank. The waveform develops a twin peak pulse when the first and second material interfaces are in close proximity to one another. The twin peak pulse contains overlapping first and second received wave pulses reflected from the first and second material interfaces, respectively. The method determines that the waveform contains a twin peak pulse when both a first peak point relating to the first received wave pulse and a valley are detected. A microwave level transmitter having an interface detection module that is configured to use the method of the present invention to detect the existence of a twin peak pulse in a waveform.

1. A method of detecting a twin peak pulse in a waveform generated by a pulse receiver of a microwave level transmitter used to detect material levels in a tank, the twin peak pulse including overlapping first and second received wave pulses reflected from first and second material interfaces, respectively, the method comprising:(a) detecting a first peak point of the waveform corresponding to the first received wave pulse; whereby a level of the first material interface can be calculated using the first peak point; and (b) detecting a valley of the waveform after detecting the first peak point, wherein the detection of the first peak point and the valley indicates that the waveform contains a twin peak pulse.
