ABSTRACT:
A method of calibrating an ultrasonic flow meter (10) first determines a static flow offset (52). Next, a dynamic flow offset (54) and a flow speed (56) are determined. An adjusted flow speed (58) is determined by subtracting the static flow offset and one half the dynamic flow offset from the flow speed to form an adjusted flow speed.
