Meter

This meter is suitable for recording consumption or delivery of various utilities such as electricity, gas, water, heat, etc.

For this purpose, the values of a physical meter are read.

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.

Inputs

Abbreviation Summary Description Value Range
Pf Power or flow If only this input is used, the meter reading is also calculated from it.
Otherwise it is only used for the output (Pf) and the user interface.
0...∞
Mr Meter reading Input for meters that send the meter reading directly as an analog value.
For meters that only send partial quantities (e.g. Smart Socket), relative metering must be activated in the settings of the block.
0...∞
R Reset Pulse: Meter reading outputs are reset.
On: Block is locked.

Properties

Summary Description Default Value
Relative metering Active: The physical meter only sends partial quantities at intervals (relative), the block adds them up and uses them to form the meter reading.
Not active: The physical meter provides its own total meter reading (absolute), the function block only maps it.

Meter reading and units

In general, a physical meter records the quantity and transfers the value to the function block at a meter reading input. The function block maps the meter reading and records the statistics for it.
The units for Pf/Mr can be selected independently of each other, as the value at input Pf is only used for output Pf and for display in the user interface.

If the input Pf is used on its own, the block takes over the function of the meter.
In this case, the units for Pf/Mr must be hour-related and must match in magnitude so that the meter reading is calculated correctly.
Examples:
Pf=kW, Mr=kWh
Pf=W, Mr=Wh
Pf=l/h, Mr=l
Pf=m³/h, Mr=m³
Pf=kg/h, Mr=kg
