Sensor assembly for measuring the average velocity in conduits or open channels

Abstract

A sensor assembly is for measuring average velocity of a fluid flowing in a closed conduit or in an open channel. The sensor assembly is adapted to measure average velocity though closed conduits of different sizes or through open channels with different fluid levels. The sensor assembly includes a housing extending across an inside of the closed conduit or to extend vertically in the section of the open channel. The housing includes pairs of electrodes and at least one associated electromagnet for measuring the velocity distribution in the closed conduit or in the open channel. An isolator allows isolation from the pairs of electrodes or from signals of the pairs of electrodes that are not in contact with the fluid flow to be measured. The isolator is configured to be adapted depending on water level in the open channel or size of the closed conduit.
