Abstract
A method for measuring a velocity of a fluid, comprising the steps of, acquiring an ultrasonic measuring signal after it has travelled in the fluid over a path of defined length; defining measurement zone of the ultrasonic measuring signal which includes a plurality of measurement lobes; for each measurement lobe, measuring a zero crossing point associated with said measurement lobe; selecting at least two zero crossing points which satisfy a predefined precision criterion; estimating a time of flight for the ultrasonic measuring signal from the selected zero crossing points; utilizing the time of flight to estimate the velocity of the fluid.
