• 沉积物输送研究

This sampler is used to measure suspended sediment transport in rivers and other water courses, from the surface down to 0.1 m above the river bottom. The sediment containing water flows through a bottle shaped sampler. The shape of this sampling body induces a low pressure at the rear face in such a way, that the water enters the nozzle of the sampler with almost the same velocity as the undisturbed flow. The sharp decrease of the velocity in the wide sampling chambers causes the sediment material to settle there. The sampler can be used in two ways:

  • Suspended on a cable for all depths from the surface to 0.5 m above the bottom. A tail fin keeps the nozzle in up-stream direction.
  • Standing in a frame on the bottom for distances of 10, 20, 30, 40 and 50 cm from the bottom. The set comprises a sampler, the frame, a number of nozzles and measuring glasses. Because of the flow-through principle a large volume of water is sampled.

04.31 好处 代尔夫特瓶

  • 可略高于流动泥沙底部采样
  • 完美的高度控制,可降至底部
  • 古铜色的结构,耐海水侵蚀


  • 需要绞车和吊艇架
  • 检查手册获取样品粒度


  • Easy to use.
  • Sturdy construction.
  • Can be used at any depth.

Handling requires a davit with depth counter and winch, due to the weight of the instrument. Simultaneous measurement of velocities is necessary.
