MSP430FR6047: Waveform Capture Based Ultrasonic Sensing Water Flow Metering Technology

Part Number: MSP430FR6047
Hi there,
Our company is planning to use MSP430FR6047 for ultrasonic water metering application and we appreciate it if you guys try to help us figure out the listed below questions ASAP;
  1. The absolute time of flight (absToF) is determined by a two-stage process, namely Acquisition, and tracking, The question at hand is: How does the tracking algorithm determine whether a signal is arriving or not and whether it is the same as a prior signal?
  2. how to select the effective Toffset value?
  3. Please attach a reference textbook that describes the correlationinterpolation, and time of flight calculation algorithms in depth.
