Measuring processes and apparatus for determining tariff values for energy consumers

A measuring apparatus for determining a tariff value for energy consumed by an energy consumer during a period of energy consumption, said tariff being dependent on the power of said energy consumed, comprising a consumption meter for measuring energy consumed during said energy consumption period, a pulse generator associated with said consumption meter for producing fixed quantity pulses each of which pulses represents the consumption of a fixed quantity of energy, a measuring and calculating means for forming measurement value each time a fixed quantity pulse is produced proportional to the reciprocal of the time intervals between said fixed quantity pulse and the immediately preceding fixed quantity pulse, a summing means for summing said measurement values during said consumption period, and an evaluation means for forming the quotient of the said summed measurement values and the measurement value for said consumption period by dividing the said summed measurement values by the said measurement value;

• said summing means and said consumption meter being in communication with a common evaluation means by way of communication channel, said quotient representing said tariff value for said consumption period.
