The Fixed Value Meter is suitable for consumers or producers whose power or flow rate is constant during operation.
In this case, the function block can calculate the quantity and thus the meter reading from 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.
Keep in mind that the calculated value does not reach the accuracy of a true measurement, since variations can occur in both supply and device power.
Together with other meter function blocks, various consumers, producers or storage units in the building can be linked via the Energy Flow Monitor for an overall display.
