The Fixed Value Meter is suitable for consumers or producers with a constant power or flow rate during operation.
In this case, the function block can calculate the meter reading based on the switch-on duration.
In this way, many devices can be recorded with little effort without having to install a physical meter. Particularly suitable are devices that are already controlled, and whose on/off status is known.
Please note that the calculated value does not provide the accuracy of a true measurement, as fluctuations may occur in both the supply and the device performance.
In combination with other meter function blocks, various consumers, producers or storages can be linked via the Energy Flow Monitor for an overall view.
