- fully automatic sampling
- sampling adapted to the runoff intensity
- water distribution only via switches
Run off measurement instrument
The measuring system is used for the detection of surface run off and the erosion materials contained therein. The surface run off water is collected in a collection channel and quantified by a tipping counter before it is filled into sample vessels or tilted. The start and the intensity of the runoff event are registered by an internal data logger.
The subsequently filling of the samples of the surface runoff in up to 24 brown glass flasks is carried out fully automatically and only via water switches. There are no bottlenecks that could add up, cause a backflow or slow down the flow rate.
The entire system is made of rust free stainless steel which is inert to the samples. It is installed underneath in order to generate the flow solely due to the difference in height and not to rely on pumps. Thus, free flow is generated and the energy consumption is minimized.
- fully automatic detection of the aeolic sediment load
- samples of the sediment material for laboratory analysis
Wind erosion sediment trap
The wind erosion sediment trap automatically records the aeolically transported sediment material. This is weighed directly in the system and then remains in the weighing pan to be available for subsequent investigations. The body of the system is completely made of stainless steel and consists of a foot, which contains a logger, accumulator and balance as well as rotatably mounted head part with wind flag for the actual sampling. The foot of the system is usually installed underneath in order to guarantee that the wind flow is influenced as little as possible and to ensure a safe stand.
