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.
