Ultrasonic flowmeter with simultaneously driven ultrasonic transducers

摘要

The present invention relates to consumption meter in the form of an ultrasonic transit time flowmeter for measuring a flow value representing a consumed quantity. The generator circuit and the ultrasonic transducers of the flowmeter are arranged so that the drive signals simultaneous drive each of the at least two ultrasonic transducers. In embodiments, detection of the flow may be based on frequency mixing, such as homodyne detection.
