1. Different principles of speed measurement
1.1 Speed measurement with pressure sensor
A pressure sensor measures a pressure difference from which the modulus of flow velocity can be deduced. Some instruments allow simultaneous measurement of flow direction.

Consider a small parallelepiped dxdydz in a laboratory coordinate system, with mass equal to unity, to which we apply the fundamental equation of dynamics (Newton's equation):
