In which cases can a pitot tube be used?

A pitot tube is often used for large pipe diameters (up to diameter 5000 mm) and for low flows or installations requiring low pressure drop. Indeed, the pitot tube induces only a very low permanent pressure drop and is therefore recommended for this type of applications.
