Gas, liquid or electricity supply or production meters

1. Scope and Applicability

This PCR governs foreground manufacturing data packages for finished meters that measure gas, liquid, or active electrical energy for supply or production accounting. It covers mechanical, electronic, and smart meters, including the measuring element, calculator or register, display, communication and power functions when fitted, enclosure, seals, and installation accessories delivered with the meter.

Every data package shall select and disclose one concrete product variant. At minimum it shall distinguish the measured medium (electricity, gas, water, or another liquid), supply versus production duty, metering principle and technology (mechanical, electronic, or smart/connected), applicable metrological class and rated measuring range, communication configuration, power configuration, enclosure rating, and included installation accessories. Results for materially different variants shall not be averaged unless production-weighted foreground records preserve those distinctions.

This PCR excludes stand-alone flow, pressure, level, voltage, current, resistance, or power sensors that are not complete supply or production meters; meter parts and subassemblies sold separately; data concentrators, head-end systems, billing platforms, and other metering services; installation work not delivered with the product; and thermal energy meters. A single smart electricity meter, flow sensor, or backend service shall not be used as a proxy for this category.

How well	Meets the declared applicable legal-metrology regime, metrological or accuracy class, rated measuring range, medium compatibility, installation configuration, enclosure rating, communication configuration, and power configuration
How long or cycle	One declared production batch and model or configuration revision; service life and operational energy are outside this manufacturing reference flow and shall be modelled separately when required
reference_flow_link	The reference output of packaging_and_dispatch, normalized to 1 kg net finished product excluding packaging

Field	Value
Reference amount	1 kg
Reference product flow	Gas, liquid or electricity supply or production meters 138fcae3-ed55-4a92-a456-38674b3e0d47
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	measured medium and, for liquids, liquid family; supply or production duty; mechanical, electronic, or smart/connected technology; measuring principle; metrological or accuracy class and governing regime; rated measuring range and pressure, voltage/current, temperature, or other applicable rated conditions; communication protocol and module boundary; internal, mains, external, or battery power arrangement; enclosure material and ingress/environmental rating; mounting arrangement; included seals, fittings, cables, antennas, communication modules, power supplies, batteries, and installation accessories; net product mass; production geography and batch period

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

The 1 kg reference is a mass-normalized manufacturing declared unit. It does not assert equal metering service among electricity, gas, water, other-liquid, mechanical, electronic, or smart variants. Comparative service studies shall additionally model the declared measurement function, accuracy, capacity, service life, own-energy use, communication infrastructure, maintenance, and replacement scenario.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid_by_subdivision	Multi-product component, assembly, calibration and packaging lines	Prefer meter-, line-, batch- or process-level metering and subdivision. Separate electricity, water, auxiliaries, rejects and emissions when direct records are available.	pep-ecopassport-pcr-ed4

Use economic allocation only when no defensible physical driver exists, and disclose the method and sensitivity.	pep-ecopassport-pcr-ed4
allocation_rework_and_scrap	Rework, manufacturing scrap and waste treatment	Return internal rework to the originating process without double counting. Assign burdens through the point waste leaves the foreground boundary; do not apply avoided-virgin-material credits inside the reference product inventory.	pep-ecopassport-pcr-ed4
allocation_variant_weighting	Product-family and multi-site datasets	Weight site and variant records by net finished production mass for the declared period and retain production totals by required qualifier. Do not average across media or technologies when the result would conceal materially different bills of materials, test routes or energy use.	pep-ecopassport-pcr-ed4
