1 Scope

GB/T 11828.6-2008 is the Chinese national standard on instruments for stage measurement - part 6: remote measuring stage gauge, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 April 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2008. Classification: ICS 17.120, CCS N12. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 11828 specifies the telemetry level indicator of product classifications, requirements, test methods, inspection rules and signs, packaging, transportation Transport, storage and operation manual. This section applies to the measurement of rivers, lakes, open channels, reservoirs and other natural water level gauge water level telemetry (hereinafter referred to as water gauge). This section does not apply to automatic hydrological forecasting system (hereinafter referred to as system) telemetry terminal.
