Venturi Tube
About Venturi Tube
The venturi tube is a
precision-engineered tube of a special shape. It is a very expensive
instrument but offers very good accuracy (approximately ± 1%) and
imposes a permanent pressure loss on the measured system of only
10-15% of the pressure difference across it. The smooth internal shape
of this type of restriction means that it is unaffected by solid
particles or gaseous bubbles in the flowing fluid, and in fact can
even cope with dilute slurries. It has almost no maintenance
requirements and its working life is very long compared to other such
devices.
