Well-established mass and volume flow rate measuring devices are reviewed, and the strengths and weaknesses of various meters and classes of meter are discussed. Modern non-invasive methods - magnetic and ultrasonic - are also discussed.Tom BruceTom Bruce, Fluid Mechanics3: Flow measurement methods...
Determining a multidimensional velocity field within microscale opaque fluid flows is needed in areas such as microfluidic devices, biofluid mechanics and hemodynamics research in animal studies. The ultrasonic particle image velocimetry (EchoPIV) technique is appropriate for measuring opaque flows by taking...

Measurement of ventilation in the resting horse requires a facemask, a flow measuring device (pneumotachograph), a differential pressure transducer (except with ultrasonic devices), a means of calibrating either flow or volume, and a recording and analysis system (see Box 15.1). ...
(2012)investigated a common scale to measure flow in video games: the Dispositional Flow Scale-2 (DFS-2) usually used to measure the tendency to experience flow in athletes. The authors showed that this scale was not a good fit for measuring theflow experiencein the gamer population, in ...
In the past years, the fluid flow in the nanopores has always attracted considerable public concern due to the development in nanofluidic devices and systems. Beskok and Karniadakis20 proposed a model for rarefied gas flows in channels, pipes and ducts with smooth surface, which was used to ...
In the previous studies, the quantification may have failed to detect the two modes due to measuring the mixed population14,39,40. In analyses of tracking particles, the accuracy of tracking decreases drastically at high signal density41. In this study, we took particular care to accurately ...
In the context of fluid mechanics, multiphase flows can be taken as simply any fluid flow system consisting of two or more distinct phases flowing simultaneously in mixture, having some level of phase separation at a scale well above the molecular level. ...
The above discussion provides a means of evaluating permeability of a porous medium experimentally by measuring the pressure drop and the flow rate in systems where these measurements are possible. In package dyeing processes, the flow velocity of fluid through the porous spaces of the package is ...
