    • A device 1 for measuring a fluid flow FF velocity and direction comprises : - a pivotable means 2 adapted to rotate at a pivotable means rotation velocity and direction depending on the fluid flow velocity and direction when in contact with the fluid flow, - a modulator 3 coupled to the pivotable means and adapted to rotate in conjunction with the pivotable means, - a fiber optical arrangement for providing an incident beam IB to the modulator and for receiving a return beam RB from the modulator, - the incident beam IB comprising an incident signal, the return beam RB comprising a modulated signal, the modulator 3 modulating the incident signal so as to form the modulated signal depending on the pivotable means 2 rotation velocity and direction. The modulator 3 comprises an encoder 30 comprising at least a first angular sector 34, a second angular sector 35 and a third angular sector 36, each angular sector having a determined attenuation coefficient so that the modulated signal comprises at least a first portion 64, a second portion 65 and a third portion 66 for each complete rotation of the encoder 30. The device 1 further comprises a processing means 6 for determining the fluid flow FF velocity and direction based on at least the first portion 64, the second portion 65 and the third portion 66 of the modulated signal.
