The most common technology in use today for measuring flow is differential pressure “dP or ΔP” (orifice plates, pitot tubes, venturis and the like). Indeed, that was the only flow measurement method I was taught in engineering school. Well, things have come a long way in the 28 years since I picked up my degree. Today coriolis, ultrasonic, vortex, thermal and magnetic flow meters have all found their niches, although dP meters are still the most common due to the large installed base.
