WebINTRODUCTION. In this chapter, we are concerned with devices defined in international standard documents. Among these, the venturi meter is one of the oldest industrial … WebA flow profile is determined by measuring the flow of a channel or duct. Flow velocity is commonly measured with Pitot tubes. Advantages of pitot tube. Installation and removal are easy and inexpensive. Because there are no moving parts, frictional losses are reduced. It is compact in size, inexpensive, and results in very little pressure loss.

"WebObviously, the venturi tee has more turbulence than the monofloral one. The fluid is pressurized to flow through a smaller area. As a result, the fluid particles collide more with each other. Ultimately, there is a high chance of the fluid flow getting more disturbed. Whereas in the monoflo tee, there is also turbulence. " - Flow nozzle vs venturi
