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.
