Title
(EN) Apparatus for transforming energy of liquid flowing in a liquid flow path
Abstract
(EN)

An apparatus for positioning thereof in a liquid flow path, comprising: a housing configured to be received in the flow path and having a liquid inlet and a liquid outlet defining a flow direction therebetween; a current generator including a shaft supported by the housing and having a rotor mounted thereon and having a plurality of vanes, the shaft extending in the housing along the flow direction allowing rotation of the rotor with the vanes by liquid passing through the generator, and a stator associated with the rotor for producing electrical signals corresponding to the rotation of the rotor; and, electrical wiring for electrically connecting the current generator to a power receiver for transferring the electrical signals thereto.
