Our interest in the measurement of air and water flow is timeless. Knowledge of the direction and velocity of air flow was essential information for all ancient navigators, and the ability to measure water flow was necessary for the fair distribution of water through the aqueducts of such early communities.
Flow measurement is one of the 'big four' need-to-know process parameters (others are temperature, pressure, and level).
