1. A sensor assembly for measuring average velocity of a fluid flowing in a closed conduit or in an open channel, said sensor assembly being adapted for measuring the average velocity through closed conduits of different sizes or through open channels with different fluid levels, the sensor assembly comprising:
a housing configured to extend across an inside of the closed conduit or to extend vertically in a section of the open channel, said housing comprising pairs of electrodes and at least one associated electromagnet for measuring velocity distribution in the closed conduit or in the open channel;
isolation means for providing isolation from the pairs of electrodes or from the signals of the pairs of electrodes that are free from contact with fluid flow to be measured;
said isolation means being configured to be adapted depending on water level in the open channel or on size of the closed conduit.
