A detection device for a liquid-conducting appliance includes a hydraulic body () defining a duct () for a flow of a liquid, and a flow sensor on the hydraulic body (), which includes an electromagnetic arrangement and a detection arrangement. The detection arrangement includes two electrode units () for detecting a potential difference induced by the flow of the liquid through an electromagnetic field generated by the electromagnetic arrangement. The hydraulic body () has two through openings on two opposite sides () of the duct (), inserted in each of which is a corresponding electrode unit (), in such a way that the electrode units () are opposed to one another and in contact with the liquid. The device () includes sealing elements at each through opening, for preventing leakage of the liquid from the duct ().

Electromagnetic detection device having a sealing arrangement and engagement elements associated with detection electrodes

An electromagnetic measuring device includes a hydraulic body defining a duct for a flow of a liquid, and a flow sensor on the hydraulic body that includes an electromagnetic arrangement for generating an electromagnetic field through the duct in a direction transverse to the flow of the liquid, and detection arrangement including two electrical detection elements for detecting a potential difference induced by the flow of the liquid through the electromagnetic field. The detection elements are associated to one and the same face of a substrate, which extends on the outside of the duct in a position corresponding to a first side of the duct. The first side of the duct has two through openings, each of which is in a position corresponding to a respective electrical detection element.
