You can use a Prandtl probe as flow velocity metering instrument mainly for open flow around solid bodies. However, it is also suitable for velocity measurement of air flow in a rectangle and round channels. The difference between stagnation and static pressure in one point of flow streamline is called dynamic pressure. Dynamic pressure represents kinetic energy, and flow velocity can be calculated using this calculator.
