Signal strength for the upstream transducer.
Signal strength for the downstream transducer.
Measured speed of sound in the fluid.
AGC DAC count for upstream gain setting.
AGC DAC count for downstream gain setting.
Upstream ultrasonic signal transit time.
Downstream ultrasonic signal transit time.
Transit time difference between upstream and downstream signals.
Current velocity/reynolds number.
K factor, based on the Reynolds number.
Percentage of peak (set to +50 by default).
Theta 3 is the angle between the ultrasonic beam and the normal to the pipe wall. It is
calculated from measured transit time and the clamp-on parameters (clamp-ons only).
