Pitot tube is employed in a variety of flow measurement applications like air speed in racing cars and Air Force fighter jets. In industries, pitot tubes are invariably put into use for measurement of
- Air flow in pipes, ducts, and stacks, and
- Liquid flow in pipes, weirs, and open channels
Since pitot tubes are trouble-free and offer consistent performance, they are appropriate for a range of environmental conditions such as in exceptionally high temperatures and an extensive range of pressures.
Pitot tubes ought to be used in applications where the minimum Reynolds number is more than 20,000 and in cases where a straight run of approximately 25 diameters can be provided upstream to the pitot tube. Besides, in areas where straightening vanes are installed, pitot tubes can find their use.
