Abstract
An apparatus for controlling a voltage controlled oscillator (20) in an ultrasonic flow meter (18) includes a comparator (28) for comparing a received signal to an estimate signal, to form an early-late signal (32). The early-late signal (32) is received by a counter (36) to form a count signal (38). A digital to analog converter (42) receives the count signal (38) and converts it to a control voltage output (40) that is coupled to the voltage controlled oscillator (20).
