The measurement of flow in pipes is important in many applications, including water management, power and energy using diesel and fuel oil, irrigation, food processing, mining and medical interventions. Several flowmeters are commercially available based on various principles such as mechanical flowmeters based upon positive displacement principle which includes popular rotameter and several gear and turbine flowmeters; differential pressure flowmeters based upon Bernoulli’s principle which includes popular Pitot-tube, Venturimeter and Orificemeter; magnetic and electromagnetic flowmeters based on Faraday’s law of electromagnetic induction and Lorentz principle; ultrasonic flowmeters based on ultrasound wave propagation principle which includes popular Doppler and transit-time flowmeters. While some flowmeters haven’t changed much, others have made significant improvements during the last few decades. Out of these flowmeters, the ultrasonic flowmeters are one of the fastest growing flow measurement devices.
