At the present time, more than one million household meters including heat cost allocators in Europe and more than eight million in the USA are remotely read.
Although automatic meter reading has not yet proved that it is economical as far as the annual reading rota and tariffs involved today are concerned when compared with the manual reading of meters and heat cost allocators, the financial advantages are obvious.
In order to justify these costs/ effort, however, it is obvious that a bus system must be designed in such a manner that not only the consumption figures of heat cost allocators but also the data of the remaining meters (gas, water, electricity) can also be read.
Instead of measuring accurately the energy consumption (eg, with calibrated heat counters), auxiliary variables are then registered (eg, with heat cost allocators), which are proportional to the energy consumption sufficiently within the respective allocation unit.
In addition, a more accurate accounting of these costs would lead to a higher transparency, and it could be assumed that a consumption-dependent allocation of these costs will force a more economical user behavior (as it is the case for heat cost allocation).
