ABSTRACT:
An apparatus for measuring the velocity of a fluid flowing in a conduit 13 comprises a differential pressure generator including first and second bluff bodies 6a, 6b which are positioned in the conduit to create a differential pressure that is a function of the velocity of the fluid. First and second pressure sampling apertures 4a', 4b'are located downstream of the first and second bluff bodies respectively, and a differential pressure sensor 9a provides an electrical signal which is a function of the difference between the pressures at the apertures.
