In Fracttal you can add two types of meters, based on their nature of registration:

Counter meters or accumulators, as their name indicates, are meters that allow readings to be recorded in ascending order based on the accumulated number of previous records. Some examples of this type of meter may be the accumulated mileage readings on a vehicle or the record of accumulated operating hours on a machine.

Non-accumulative meters correspond to meters that only record the momentary value of the reading, where said reading can fluctuate or oscillate over time. Some examples of this type of meters can be the temperature records of a refrigerated room, which can vary over time, or recording variables such as an equipment’s voltage and amperage, which can vary depending on the operating conditions.
