Consumption

The Avelon system provides different methods to calculate consumption values. The type of calculation is particularly relevant for charts, custom data points and plausibility checks.

Consumption types

Positive consumption	A change in consumption is only detected when the meter reading increases.
Negative consumption	A change in consumption is only detected if the meter reading drops.
Positive and negative consumption	A change in consumption is always detected when the meter reading changes.
Positive consumption with reset	A change in consumption is only detected when the meter reading increases. If the meter reading drops by more than 20% relative to the previous value, this is interpreted as a reset (see next section).

Meter reset

The Avelon system generally assumes that meter readings are always recorded with increasing values. In the event that a meter is reset to 0 by a manual reset or meter overflow, the Avelon system will automatically compensate for this and still interpret it as a continuous meter reading.

However, this mechanism is only effective if the new meter reading is at least 20% lower than the previous meter reading. This should normally be the case for a reset to 0.

At least two valid recorded values are required to calculate a consumption value. Zero meter readings are ignored in the calculation.

Note

Meter replacement

The automatic compensation of the meter reset also allows a meter replacement to be carried out without additional intervention in the Avelon control system, as long as the rule described above is observed and the meter reading of the new meter is at least 20% lower than the last meter reading of the replaced meter.
