NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 24155 : 2016 ‘Hydrometry - Hydrometric data transmission systems -Specification of system requirements’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards after recommendation of the Hydrometry Sectional Committee and approval of the Water Resources Division Council.

This standard was originally published in 2015 and was based on ISO/TS 24155 : 2007. The first revision of this standard has been undertaken to align it with the latest version of ISO 24155 : 2016.

The text of ISO Standard is being considered as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
