Abstract: A water meter (1) comprising:



a volume flow-measuring device (2) by means of which a volume flow of a liquid flowing through a water pipe (3) can be measured from outside the water pipe (3); and
a clamping device (4) by means of which the water meter (1) can be clamped to the water pipe (3).




In addition, a method for attaching a water meter (1) to a water pipe (3).

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: Method for monitoring a water supply network (1) in an infrastructure object (2) having water pipes (3) and at least one measuring device (4) for monitoring the water supply network (1) that contains at least the following steps: a) determining at least one structure parameter (5) which characterizes at least one structure of the infrastructure object (2) or the water supply network (1); b) determining at least one water parameter (6) using the at least one measuring device (4), and c) determining at least one probability value (7) for water damage, wherein at least one structure parameter (5) and the at least one water parameter (6) are taken into consideration.
