Instruments and apparatus for measuring or checking the flow, level, pressure or other variables of liquids or gases

1. Scope and Applicability

This PCR applies to complete, marketable instruments and apparatus whose primary function is to measure or check flow, level, pressure, or another physical process variable of a liquid or gas. It covers contact and non-contact instruments, mechanical and electronic instruments, local indicators and transmitters, and instruments with integral display or communications. The declared product must be a complete instrument capable of its intended measurement or checking function after calibration and configuration.

The product configuration shall be classified by measured-variable class (flow, level, pressure, or other_liquid_or_gas_variable), contact mode (contact or non_contact), operating architecture (mechanical or electronic), process connection, enclosure protection rating, and intended medium. Electronic configurations shall additionally declare output or communication type and power-supply arrangement. IEC 62828-1 distinguishes pressure, level, and flow process measurement transmitters and analogue and digital transmitters; IEC 60529 provides the enclosure-protection classification used for the declared IP rating.

Excluded are gas, liquid, or electricity supply or production meters used for trade or utility settlement; automatic regulating or controlling instruments and apparatus; navigational, hydrological, or meteorological instruments; physical or chemical analysis instruments; and standalone sensing elements, transducers, housings, electronics modules, displays, communication modules, process connections, spare parts, or other components that cannot perform the complete measurement function by themselves.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_avoid_by_subdivision	multi_product_manufacturing	Avoid allocation by separating component manufacture, electronics, assembly, calibration and packaging records by line, model, configuration, batch or time period whenever meters and production records permit.	abb-pgs300-epd-2024
allocation_physical_fallback	shared_energy_auxiliaries_and_waste	When subdivision is not possible, allocate shared electricity, utilities, auxiliaries and waste using the causal physical driver: metered machine time or energy first, then accepted processing time, component mass or released product mass; disclose the driver and test sensitivity for material shared burdens. Economic allocation is not the default.	abb-pgs300-epd-2024
allocation_rework_and_scrap	rework_scrap_and_recycling	Return rework burdens to the configuration that caused them. Assign waste treatment to the generating process and do not credit recovered material inside the factory-gate dataset; any recycling substitution or benefit belongs to an explicitly declared downstream scenario.	abb-pgs300-epd-2024; siemens-sitrans-lr250-epd-2023
allocation_no_controller_service_credit	measurement_service_benefits	Do not credit process-energy, water, safety or control-system benefits enabled by the instrument against its manufacturing burden; such avoided-impact claims belong to a separate consequential or downstream system study.	iec-62828-1-2026

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence

Product specification, functional description, configuration code and released-product inspection
dq_configuration_completeness	Product family and configuration mix	Preserve measured-variable, contact mode, mechanical/electronic architecture, measurement principle and range, medium, sensing/wetted materials, housing, process connection, protection rating, electronics, display/communication, power and calibration attributes for each configuration.	Revision-controlled BOM, drawings, technical specification, calibration record and configuration weighting file
