ABSTRACT:
An ultrasonic flow meter (10) has a pair of transducers (36, 38). A first (36) of the pair of transducers is coupled to a first divider (18) having a first predetermined divisor. A second (38) of the pair of transducers is coupled to a second divider (24) having a second predetermined divisor. The second predetermined divisor is not equal to the first predetermined divisor. An input (16) of the first divider (18) is coupled to a first oscillator (12). An input (22) of the second divider (24) is coupled to a second oscillator (14). A decoder circuit (50) is coupled to an output (15) of the first oscillator (12) and an output (20) of the second oscillator (14). The decoder circuit (50) determines a difference frequency.
