Abstract: Previous presentations on history of high Accuracy Ultrasonic flow meters have always made the assumption that everything started with the British gas meter. In fact this is far from the truth we have to go back to the early 1960 s to see the beginnings of such meters, and these were generally liquid meters. One of the first pioneers was Al Brown, initially he used the sing around method to give a frequency proportional to velocity, to avoid the need for high resolution timing. Later he refined his me ters to used analogue timing methods.
