FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62828-5 has been prepared by subcommittee 65B: Measurement
and control devices, of IEC technical committee 65: Industrial-process measurement, control
and automation.
The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for
the IEC 61298 series.
The text of this International Standard is based on the following documents:

INTRODUCTION
Most of the current IEC standards on industrial measurement transmitters are rather old and
were developed having in mind devices based on analogue technologies. Today's digital
industrial and process measurement transmitters are quite different from those analogue
transmitters: they include more functions and newer interfaces, both towards the computing
section (mostly digital) and towards the measuring section (mostly mechanical). Even if some
standards dealing with digital transmitters already exist, they are not sufficient, since some
aspects of the performance are not covered by appropriate test methods.
In addition, the existing IEC test standards for industrial and process measurement transmitters
are spread over many documents, so that for manufacturers and users it was difficult,
impractical and time-consuming to identify and select all the standards to be applied to a device
measuring a specific process quantity (pressure, temperature, level, flow, etc.).
To help the manufacturers and users, it was decided to review, complete and reorganize the
existing IEC standards on the industrial and process measurement transmitters and to create a
more suitable, effective and comprehensive standard series that provides, in a systematic way,
all the needed specifications and tests for the different industrial and process measurement
transmitters.
To solve the issues mentioned above and to provide an added value for the stakeholders, the
new standard series on industrial and process measurement transmitters covers the following
main aspects:
• applicable normative references;
• specific terms and definitions;
• typical configurations and architectures for the various types of industrial and measurement
transmitters;
• hardware and software aspects;
• interfaces (to the process, to the operator, to the other measurement and control devices);
• physical, mechanical and electrical requirements and relevant tests; clear definition of the
test categories: type tests, acceptance tests and routine tests;
• performances (their specification, tests and verification);
• environmental protection, hazardous areas application, functional safety, etc.;
• structure of the technical documentation.
To cover in a systematic way all the topics to be addressed, the standard series is organized in
several parts. At the time of publication of this document, IEC 62828 consists of the following
parts:
• IEC 62828-1: General procedures for all types of transmitters
• IEC 62828-2: Specific procedures for pressure transmitters
• IEC 62828-3: Specific procedures for temperature transmitters
• IEC 62828-4: Specific procedures for level transmitters
• IEC 62828-5: Specific procedures for flow transmitters
In preparing the IEC 62828 series (all parts), many test procedures were taken, with the
necessary improvements, from the IEC 61298 series. Because the IEC 61298 series is currently
applicable to all process measurement and control devices, when the IEC 62828 series is
completed, the IEC 61298 series will be revised to harmonize it with the IEC 62828 series,
taking out from its scope the industrial and process measurement transmitters. During the time
when the scope of the IEC 61298 series is being updated, the new IEC 62828 series takes
precedence for industrial and process measurement transmitters.
When the IEC 62828 series is published, the IEC 60770 series will be withdrawn.

117 FOREWORD
118 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
119 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
120 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
121 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
122 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
123 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
124 in the subject dealt with may participate in this preparatory work. International, governmental and non-
125 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
126 with the International Organization for Standardization (ISO) in accordance with conditions determined by
127 agreement between the two organizations.
128 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
129 consensus of opinion on the relevant subjects since each technical committee has representation from all
130 interested IEC National Committees.
131 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
132 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
133 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
134 misinterpretation by any end user.
135 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
136 transparently to the maximum extent possible in their national and regional publications. Any divergence
137 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
138 the latter.
139 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
140 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
141 services carried out by independent certification bodies.
142 6) All users should ensure that they have the latest edition of this publication.
143 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
144 members of its technical committees and IEC National Committees for any personal injury, property damage or
145 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
146 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
147 Publications.
148 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
149 indispensable for the correct application of this publication.
150 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
151 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

174 INTRODUCTION
175 Most of the current IEC standards on industrial measurement transmitters are rather old and
176 were developed having in mind devices based on analog technologies. Today’s digital
177 industrial and process measurement transmitters are quite different from those analog
178 transmitters: they include more functions and newer interfaces, both towards the computing
179 section (mostly digital) and towards the measuring section (mostly mechanical). Even if some
180 standards dealing with digital transmitters already exist, they are not sufficient, since some
181 aspects of the performance are not covered by appropriate test methods.
182 In addition, the existing IEC test standards for industrial and process measurement
183 transmitters are spread over many documents, so that for manufacturers and users it was
184 difficult, impractical and time-consuming to identify and select all the standards to be applied
185 to a device measuring a specific process quantity (pressure, temperature, level, flow, etc.).
186 To help the manufacturers and users, it was decided to review, complete and reorganize the
187 existing IEC standards on the industrial and process measurement transmitters and to create
188 a more suitable, effective and comprehensive standard series that provides, in a systematic
189 way, all the needed specifications and tests for the different industrial and process
190 measurement transmitters.
191 To solve the issues mentioned above and to provide an added value for the stakeholders, the
192 new standard series on industrial and process measurement transmitters covers the following
193 main aspects:
194 • Applicable normative references
195 • Specific terms and definitions
196 • Typical configurations and architectures for the various types of industrial and
197 measurement transmitters
198 • Hardware and software aspects
199 • Interfaces (to the process, to the operator, to the other measurement and control
200 devices)
201 • Physical, mechanical and electrical requirements and relevant tests; clear definition of
202 the test categories: type tests, acceptance tests and routine tests
203 • Performances (their specification, tests and verification)
204 • Environmental protection, hazardous areas application, functional safety, etc.
205 • Structure of the technical documentation.
206 To cover in a systematic way all the topics to be addressed, the standard series is organized
207 in several parts. At the moment of the publication of this document, IEC 62828 consists of the
208 following parts:
209 • Part 1: General procedures for all types of transmitters
210 • Part 2: Specific procedures for pressure transmitters
211 • Part 3: Specific procedures for temperature transmitters
212 • Part 4: Specific procedures for level transmitters
213 • Part 5: Specific procedures for flow transmitters
214 In preparing the IEC 62828 series (all parts), many test procedures were taken, with the
215 necessary improvements, from the IEC 61298 series (all parts). As the IEC 61298 (all parts) is
216 currently applicable to all process measurement and control devices, when the IEC 62828 (all
217 parts) is completed, IEC 61298 (all parts) will be revised to harmonize it with IEC 62828 (all
218 parts), taking out from its scope the industrial and process measurement transmitters. During
219 the time when the scope of IEC 61298 (all parts) is being updated, the new IEC 62828 series
220 takes precedence for industrial and process measurement transmitters.

231 1. Scope
232 This Part 5 of the IEC 62828 standard series establishes specific procedures for testing flow
233 transmitters used in measuring and control systems for industrial process and for machinery
234 control systems. For general test procedures, reference is to be made to Part 1 of the
235 standard, applicable to all types of transmitters.
236 The IEC 62828 Part 5 – together with Part 1 – is the reference standard for testing every type
237 of flow transmitters, including not only for liquids but also for gases and for steam.
238 This standard “industrial flow transmitters” consistently covers all types of flow transmitters
239 used in measuring and control systems for industrial process and for machinery.
240 2. Normative references
241 2.1 Normative references
242 The following documents, in whole or in part, are normatively referenced in this document and
243 are indispensable for its application. For dated references, only the edition cited applies. For
244 undated references, the latest edition of the referenced document (including any
245 amendments) applies.
246 The normative references listed in Clause 2 of Part 1 apply.

292 uses this information to establish a relation for obtaining a measurement result from an
293 indication
294 Note 1 to entry: Calibration may be expressed by a statement, calibration function, calibration diagram, calibration
295 curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of the indication
296 with associated measurement uncertainty.
