Scope

GB/T 27992.1-2011 is the English-translated version of 水深测量仪器第1部分：水文测杆.

GB/T 27992.1-2011 sets the terms and definitions, the classification, the technical requirements, and the inspection rules, marking, packaging, transport, storage and operation manual for the hydrologic sounding rod.

Clause 1 applies it to rods used for direct measurement of water depth and for positioning the measuring point of suspended instruments such as current meters and samplers, in open channels and tidal estuaries, and sets out no exclusion.

It is the first of the four parts of GB/T 27992, the others covering the sounding hammer, the ultrasound or echo sounder and the pressure sounder, and its foreword declares that its technical content is mutually consistent with GB/T 15966-2007 and GB/T 13336-2007.

Clause 2 cites GB/T 13336-2007, GB/T 15966-2007, GB/T 18522.6, GB/T 19677-2005 and SL 108-2006, while clause 3 adds no definition of its own and adopts those of GB/T 19677-2005.

Clause 4, on categories and model designation, divides the rods into handheld and mechanically operated types, the handheld ones into a general type for depths of no more than 3 m and velocities of no more than 2 m/s that can sound alone or assist velocity measurement, a single sounding type, whose depth and velocity limits the draft prints on the wrong line, and a wading rod for shallow river measurement, and the mechanically operated ones into long rod, semi-free declination rod and cableway rod, generally used at depths of no more than 6 m and velocities of no more than 2 m/s.

For each type the draft names the basic components, among them the shaft part, the positioning part, a signal socket part, a direction indicator part and a coupling part.

The draft breaks off inside clause 4, so nothing can be said here about the technical requirements or the inspection clauses themselves. The page puts the part forward from the Ministry of Water Resources and places it with the hydrological instruments subcommittee SAC/TC119/SC1. It was issued on 30 December 2011 and has applied since 1 June 2012.

Foreword

GB/T 27992 "depth measuring instrument" is divided into four parts.

--- Part 1. hydrology measuring rod;

--- Part 2. sounding hammer;

--- Part 3. Ultrasound (echo) sounder;

--- Part 4. put pressure sounder. This is Part 1 GB/T 27992 of.

This portion of the GB/T 15966-2007 "hydrologic instrument basic parameters and general technical conditions", GB/T 13336-2007 "hydrological instruments Series spectrum "and other standards consistent with each other on the technical content. This section drafted in accordance with GB/T 1.1-2009 given rules.

This section proposed by the People's Republic of China Ministry of Water Resources.

This part of the National Technical Committee of Standardization Technical Committee hydrological hydrological instruments (SAC/TC119/SC1) centralized.

4.1 Categories

Hydrometry with the spindle can generally be divided into handheld spindle and spindle-operated machinery.

a) handheld spindle can be divided into three types.

1) General formula. Usually at a depth of no more than 3m, using a flow rate of not more than 2m/s. Sounding separately, can also be assisted flow measurement.

The basic components are generally. the shaft portion (the two classifications with toe and without toe) positioning portion, the signal adapter socket unit Points, direction indicator portion and the coupling portion and the like.

Generally used when at a depth of no more than 6m, the flow rate does not exceed 2m/s. 2) single sounding style. The basic components are generally. Rod Body parts, and other positioning portion (zoning toe and without two kinds toe).

3) wading with a pole. Usually suitable for wading in shallow river measurements, the basic structure and general formula or a single measure of its depth basic formula the same.

b) mechanically-operated spindle. spindle-operated machinery can be divided into long spindle, the spindle and semi-free declination cableway with a pole in three types, general When used in water depths of no more than 6m, the flow rate does not exceed 2m/s. The basic components are generally. a shaft portion connected to the lever part, the United Then bolts.
