European standards: heat cost allocators, heat and water meters
The classical registration and measuring devices for the consumption-based billing of heating and water are heat cost allocators, water and heat meters. For all these devices there exist proper European product standards.
As the publication of standards is prohibited for reasons of copyright, we can only list the relevant standards. Further references to European standards with the respective links to the national institutions for standards you will find at the

European standards for heat cost allocators
EN 834 – Heat cost allocators for the determination of the consumption of room heating radiators (appliances with electrical energy supply)
EN 835 – Heat cost allocators for the determination of the consumption of room heating radiators (appliances without electrical energy supply based on the evaporation principle)
Both standards were elaborated at the CEN/TC 171.
European standards for heat meters
EN 1434-1 heat meters, part 1: General requirements
EN 1434-2 heat meters, part 2: Constructional requirements

EN 1434-4 heat meters, part 4: Pattern approval tests
EN 1434-5 heat meters, part 5: Initial verification tests
EN 1434-6 heat meters, part 6: Installation, commissioning, operational monitoring and maintenance
These parts of the standards were elaborated at the CEN/TC 176.
European standards for water meters
EN 14154-1 water meters, part 1: General requirements
EN 14154-2 water meters, part 2: Installation and conditions of use
EN 14154-3 water meters, part 3: Test methods and equipment
