Flow meters are used to measure the rate of flow of liquids or gases, just like electric meters measure the amount of electricity consumed. However, unlike electric meters, which are either ...

These are the type of flow meters that measure the velocity of liquid or gas by using the principle of ultrasound or sounds waves. Fast digital signal processors and sophisticated signal analysis ...

Figure 1: Predator–prey oscillations in transitional turbulent pipe flow at nominal Re = 2,600, for a pipe of radius R = D/2. These numerical results suggest that the large-scale zonal flow and the ...
