4 Categories and model name

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. ......
