Selection guide EQ meters.

How do I select the best meter for my application?
There are many versions of EQ meters in order to meet your requests. The EQ program comprises meters with different
functionalities such as tariffs, communication interfaces or advanced clock functions. Spend a little time to evaluate
the functions and imagine how they could add extra value to your metering. For example, the input counter (from Silver
level) on an EQ meter can be used to count products produced by a machine and be read out together with the energy
consumption of the same machine. In one easy go you can allocate energy to any produced product from one source.
Another useful function is previous values (from Gold level). If you charge users in intervals the meter can secure the data
even in the event of a broken communication link. You can collect the correct interval data later and also make it visible for
your counterpart immediately on the meters display in case of any discussions.
