Long-term accuracy
Correct billing requires reliable data and correct measuring
The energy meter is a measuring instrument like the petrol pump or the weighing scale at the butcher. Customers rely on their accuracy, in fact they have to; and for this reason the demonstrability of the accuracy becomes crucial. The energy meter is the most important point of reference between utility and customer. And since the energy meter functions as the utility's cash register it is also a very sensible point. A customer merely suspecting the energy meter of being inaccurate could destabilize the relationship and make it harder to enter into a dialogue on other issues too. Our energy meters are subject to several tests at both local and international authorities in order to document measuring stability over time. Tests show a significant difference between the various makes regarding measuring stability.
