Answer Posted / berry
As a fluid flows past a bluff body, or shedder at low
velocity, the flow pattern remains streamlined. however, as
velocity increases the fluid separates from each side of
the shedder and swirls to form vortices downstream of the
shedder.A svortex is an area of swirling motion with high
local velocity and thus lower pressure than the surrounding
fluid. the amount of vortex generation is directly
proportional to the velocity of the fluid.Therefore, we can
use the relationship Q=AV to obtain the flow rate. a
pressure sensor that is mounted on the upstream side of the
flow shedder detects the pressure that is exerted on the
shedder by the formation of vortices.The signal from the
pressure sensor is converted into a calibrated flow signal
by an electronic circuit in a flowmeter.
