Introduction :
Venturi Tube usually used for flow at high fluid
velocities since it is more rugged
and
more resistant to corrosion It is not recommended
for highly viscous liquids or those
containing large amount of
sticky solids.
An elliptical restriction
in the flow but with no outlet area for pressure
recovery, more compatible for gas service than
for liquids
Advantages : Can
be used at higher velocities with little damage
to the nozzle surface, which allows using
smaller sized meters for a given flow rate
Throat tap nozzles have the lowest stated
tolerances of all head devices, but require
calibration to prove and have restricted beta
ratio changes.
Disadvantages : Expensive, Difficult to
install and remove for cleaning - and therefore
are seldom, cleaned
Data base for coefficient tests much smaller
than for orifices, calibration required for best
accuracy Limited range of Reynolds numbers

Flow Nozzles
The Daniel® Flow Nozzle is a differential
flowmeter that creates a flow restriction for,
typically, high-velocity, non-viscous, erosive
flows.Flow Through a Flow Nozzle Though
geometrically different from an orifice plate, a
flow nozzle is Fig.3.26 shows a flow nozzle
which is just a converging nozzle placed in a
pipe. www.aeromech.usyd.edu.
