Abstract: A liquid sensor, including: a) a housing; b) at least one sensor having at least two metallic contact surfaces for detecting a liquid; and c) a processing unit for processing sensor signals of the at least one sensor, a function of the liquid sensor being controllable by an actuation of at least one of the metallic contact surfaces. A method for controlling a function of a liquid sensor is also proposed.

Abstract: A method for operating a sanitary fitting, and to a sanitary fitting. The sanitary fitting is equipped to deliver a water jet and has at least one manual actuator for manual regulation of at least one water jet flow rate or a water jet temperature, and a sensor arrangement that is equipped for sensor-controlled regulation of a predefined water jet flow rate and a predefined water jet temperature. The sensor arrangement is equipped to detect the presence of an object in an external detection area and a control unit is provided to distinguish whether the object detected first is a water jet or a different object.

Abstract: A method for detecting a leak, having at least the following steps: a) capturing a flow volume of a liquid through a liquid line during a multiplicity of liquid removal processes; b) comparing the flow volumes of the liquid in the respective liquid removal processes with an alarm value; c) outputting an alarm signal if the flow volume of the liquid in a liquid removal process exceeds the alarm value; d) adapting the alarm value on the basis of a frequency of the occurrence of the flow volumes of the liquid in the liquid removal processes above an adaptation value.

Abstract: A method for detecting a leak in a fluid line, having at least the following steps: closing the fluid line with a valve to create a pressure chamber in the fluid line; determining a first pressure drop in the pressure chamber; opening the valve after completing the determination of the first pressure drop; closing the fluid line with the valve to create the pressure chamber in the fluid line again; determining a second pressure drop in the pressure chamber; and comparing the first pressure drop with the second pressure drop. Also, a water meter is provided with a valve, a flow sensor, and a pressure sensor, which are connected in a data-carrying manner to a controller, wherein the controller is set up to carry out the method according to the invention.
