Measurement of Fluid Flow with Different Velocity Profiles by New Built Ultrasonic Flowmeter

The paper describes the development of a non-invasive flowmeter for lower flow rates and its first tests. This gauge is physically based on interaction fluid with an ultrasonic signal that passes through from transmitter to receiver. Ultrasonic flowmeters are currently relatively commonly used gauges, whose advantages such as non-invasiveness (i.e. zero pressure losses) ability seamlessly measure any (for example opaque) liquids, without contact liquid, widely known. However, there still parts measurement chain undergoing research development. It can be processing itself (mainly), design solution, different cases (measurement in field uniform velocity profile, axisymmetric general profile), validation applied approaches, evaluation uncertainties. itself, which described paper, will trouble-free air engineering, but also serves training device building more complex gauge. Therefore, this contains transmitters receivers than it usual all transmitter-receiver combinations captured during measurement. called tomograph principle outlined paper. Here, so far, reconstructed vector field.
