ABSTRACT:
A flow measurement system and method uses enhanced phase detection based on a ratio of amplitudes of summations of two oppositely propagating acoustic signals. A need for direct time measurement and extensive difference calculation is consequently avoided so that in some implementations compact, simple, low power analog circuitry can be used.
