  • Patent number: 11029186
    Abstract: A level transmitter includes an analog-to-digital convertor clock signal generator that receives a transmitter clock signal that is used to establish when an incident signal is transmitted toward a material boundary. The analog-to-digital convertor clock signal generator uses the received transmitter clock signal to generate an analog-to-digital convertor clock signal. An analog-to-digital convertor samples an analog waveform based on the analog-to-digital convertor clock signal and generates a digital value for each sample of the analog waveform. An analysis module analyzes the digital values to determine a distance to the material boundary.
