Abstract: A detection device for a liquid-conducting appliance includes a hydraulic body (2) defining a duct (3) for a flow of a liquid, and a flow sensor on the hydraulic body (2), which includes an electromagnetic arrangement and a detection arrangement. The detection arrangement includes two electrode units (20) for detecting a potential difference induced by the flow of the liquid through an electromagnetic field generated by the electromagnetic arrangement. The hydraulic body (2) has two through openings on two opposite sides (3a, 3b) of the duct (3), inserted in each of which is a corresponding electrode unit (20), in such a way that the electrode units (20) are opposed to one another and in contact with the liquid. The device (1) includes sealing elements at each through opening, for preventing leakage of the liquid from the duct (3).
