Full title and description

Industrial-process measurement and control — Data structures and elements in process equipment catalogues — Part 12: Lists of properties (LOPs) for flow measuring equipment for electronic data exchange. This part specifies Operating Lists of Properties (OLOP) and Device Lists of Properties (DLOP) intended to standardize the description of flow measuring equipment for use in e‑catalogues, engineering and procurement systems, and for automated data interchange between manufacturers, vendors and users.

Abstract

IEC 61987-12:2016 defines standardized sets of properties (LOPs) used to describe the functional, operational and device-specific characteristics of flow measuring equipment (flow meters, transmitters and associated devices) to support consistent electronic data exchange. It provides an OLOP for operating parameters and a series of DLOPs for typical flow‑measuring device types, together with rules for structure, cardinality and representation to enable automated processing by software and catalog systems.

Scope

This part of IEC 61987 specifies lists of properties and the data-structure approach for describing flow measuring equipment to be used in electronic data exchange. It covers the definition and organization of OLOP (operating properties) and DLOP (device properties) relevant to flow meters and associated transmitters and supplies guidance on block structures, cardinality, polymorphism and data element formats so that catalogues and information systems can exchange device descriptions unambiguously. The intent is to harmonize product descriptions used in catalogues, procurement and engineering tools.

Key topics and requirements

• Definition of Operating List of Properties (OLOP) for process-side and operational parameters (measuring points, base conditions, operating conditions).
• Definition of Device Lists of Properties (DLOP) for typical flow‑measuring device types (meters, transmitters, sensors) including device‑specific attributes and configurable blocks.
• Specification of generic block structure, cardinality and polymorphism to represent variable device configurations and optional blocks.
• Rules for data element types, units, value ranges, identifiers and required/optional status to ensure machine‑readable, consistent e‑catalogue entries.
• Guidance to enable mapping of LOPs into electronic catalogues, engineering databases and procurement systems for automated processing.

Typical use and users

Typical users include flow‑meter and instrumentation manufacturers (for creating e‑catalogue data), systems integrators and automation vendors (for importing device definitions), process instrumentation engineers and procurement specialists (for selecting and comparing devices using standardized property sets), and software developers of catalogue, PLM and ERP systems that exchange equipment data electronically. National committees and standards developers also use the document as a reference when creating related LOP parts.

Related standards

IEC 61987-12 is one part of the IEC 61987 series (LOPs for process equipment). Closely related parts include the generic structures and fundamentals (e.g., IEC 61987-11 / IEC 61987-1 and other equipment-specific parts covering analysers, transmitters and different device families). Newer and companion parts and higher-level database documents in the 61987 family (including recent additions and the 100/41 series) provide complementary generic structures and data‑base guidance.

FAQ

Q: What is this standard?

A: IEC 61987-12:2016 is the IEC international standard that defines Lists of Properties (LOPs) used to describe flow measuring equipment for electronic data exchange, providing OLOP and DLOP definitions and rules for structuring those properties.

Q: What does it cover?

A: It covers the content and structure of property lists for flow measuring devices — operational parameters, device attributes, block structures, cardinality and representation formats — so that equipment descriptions can be exchanged reliably between catalogues and software systems.

Q: Who typically uses it?

A: Manufacturers of flow meters and transmitters (for publishing e‑catalogue entries), systems integrators and automation vendors (for importing device definitions), process engineers, procurement teams, and software vendors creating or consuming device catalog data.

Q: Is it current or superseded?

A: IEC 61987-12 was published in 2016 (Edition 1.0) and is shown as the published/active part for flow measuring equipment; the IEC catalogue indicates the document’s publication and edition details and lists the series road‑map for future related parts. Users should verify national adoptions or later revisions if they need the very latest status.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61987 series (Lists of Properties for process equipment). The series contains multiple parts addressing generic structures, device families and database-level guidance; IEC 61987-12 specifically addresses flow measuring equipment within that series.

Q: What are the key keywords?

A: LOP, OLOP, DLOP, flow meter, flow measuring equipment, electronic data exchange, e‑catalogue, data structures, IEC 61987.
