Claim One:
1. An electricity meter comprising a first current probe, a first voltage probe and a display unit memorizing its contents, wherein said meter comprises a fuzzy logic processor connected to said first voltage and current probes, and having a fuzzy logic decision-making computer with a non-volatile memory available to store membership functions having predetermined values for upper and lower threshold voltage values that are recorded during a learning stage where a predetermined voltage and current are imposed on voltage and current probes to determine threshold values corresponding to the first voltage and current probes and to store decision rules representing logic decisions to provide a value in function of the membership value associated to each membership function where the membership functions will fix weighting coefficients depending on measured threshold values and the weighting and mean of the decision rules provide an instantaneous measured power, and wherein said computer takes a decision according to said rules that is weighted by the membership functions and is aimed at incrementing the contents of the display unit to represent an accumulation of the instantaneous measured power.
