Heat meters are devices which are mounted in a water cycle, can measure its heat output and save the data recorded. A distinction is made between heat meters and combined heat/cold meters. Heat meters record temperatures in the water circuit’s supply and return flow as well as the volume flow rate, and assume a pure heat output of the pipe system (heating operation) for the consumption calculation. In contrast, combined heat/cold meters record both the heat output and the heat input of the pipe system (cooling operation). The data of both operating modes are managed in separate memories. Both device types can display and/or store different values, e.g. the cumulated values at a selectable due date or end-of-the-month values and a fault message in case of an error.
