Abstract
A method for locating a leak (19) in a water supply network with a water source (11) and one or more water consumption meters (21, 22) on the consumer side. The method includes calculating a length of the pipe (17) between the consumption meter (21) and the leak (19) location based on a temporal temperature curve and a quantity of water flowing through the at least one consumption meter (21).

A method for locating a leak in a water supply network, the network comprising at least one water source, a main line with secondary lines branching off the main line and one or more electronic water consumption meters on a consumer side, the method comprising the steps of:
- allowing the water temperature in the secondary lines to adapt to the temperature of the environment in the ground;
- calculating a length of a pipe between at least one of the one or more electronic water consumption meters and a leak position based on a temporal temperature curve of the water flowing through the at least one of the one or more electronic water consumption meters and a quantity of water flowing through the at least one of the one or more electronic water consumption meters, wherein the flow in the pipe is stopped for a period of time before the temporal temperature curve of the water flowing through the at least one of the one or more electronic water consumption meters is determined.
A consumption meter in a water supply network, the network comprising at least one water source, a main line with secondary lines branching off the main line and an ultrasonic consumption meter as one or more electronic water consumption meters on a consumer side, the ultrasonic consumption meter comprising:
- means for locating the leak in the water supply network, which is configured to calculate a length of a pipe between the ultrasonic consumption meter and a leak position based on a temporal temperature curve of the water flowing through the ultrasonic consumption meter and a quantity of water flowing through the ultrasonic consumption meter, wherein the water temperature in the secondary lines adapt to the temperature of the environment in the ground;
- a flow stopping means, wherein the flow in the pipe is stopped for a period of time via the flow stopping means before the temporal temperature curve of the water flowing through the at least one of the ultrasonic consumption meter is determined.
A method for locating a leak in a water supply network, the method comprising:
- providing a network comprising at least one water source, a main line with secondary lines branching off the main line and at least one electronic water consumption meter on a consumer side;
- allowing a water temperature in at least one of the secondary lines to adapt to a temperature of an environment in the ground to provide an adapted ground water temperature in the at least one of the secondary lines;
- determining a temporal temperature curve of the water flowing through the at least one electronic consumption meter and determining a quantity of water flowing through the at least one electronic water consumption meter;
- determining a length of a pipe between the at least one electronic water consumption meter and a leak position in at least one of the secondary lines based on the temporal temperature curve of the water flowing through the at least one electronic water consumption meter and the quantity of water flowing through the at least one electronic water consumption meter and the adapted ground water temperature, wherein the flow in the pipe is stopped for a period of time before the temporal temperature curve of the water flowing through the at least one electronic water consumption meter is determined.
