Abstract
The present invention relates to a consumption meter for measuring consumption data of either a hot or a cold liquid supplied to a consumer site (2). The consumption meter comprises a flow meter unit (5) arranged for mount at either an inlet side (3) or an outlet side (4) of the consumer site, and arranged for measuring a flow quantity of the supplied liquid; an inlet temperature sensor (6) for measuring an inlet temperature of the supplied liquid medium, and an outlet temperature sensor (7) for measuring an outlet temperature of the supplied liquid medium; a calculator unit (8) configured to determine consumption values based on the flow quantity, the inlet temperature and the outlet temperature. The consumption meter comprises at least two legally verified consumption registers (R1, R2) for storing consumption values verified for billing. Each of the legally verified consumption registers are associated with an operational state of the consumption meter, so that the consumption meter is capable of measuring legally verified consumption data for each of the at least two operational states. The operational state is determined at the consumer site from an input.
