The Bed Load Sampler is a precision-designed, cable-suspended device specifically engineered for efficient sampling of sediment and particulate matter transported along the bottom of a stream or river bed. Weighing approximately 18 kg, this sampler features a 3" x 3" (76 mm x 76 mm) opening with a 1.4 expansion ratio to optimize sediment capture while maintaining flow conditions. The sampler incorporates a tailfin mechanism that ensures accurate flow direction orientation, enhancing the precision of sampling activities. Additionally, it includes a sliding collar that enables adjustment of the balance point according to varying stream flow conditions, ensuring reliable performance across diverse environments. The collar is calibrated to position the sampler so that the water touches the tail first, promoting rapid alignment with the streamlines of flow. This unique suspension attitude guarantees that, when lifted from the bed, the sampler's orifice lifts immediately to prevent any loss of sample, ensuring representative and accurate sediment collection for environmental monitoring, hydrology studies, or sediment transport analysis. This bed load sampler is a robust and indispensable tool for hydrologists, environmental scientists, and water resources professionals engaged in sediment transport and riverbed analysis.

The sliding collar allows adjustment of the sampler's balance point based on stream flow velocity and turbulence, ensuring the device maintains correct orientation and stability, which improves sediment capture accuracy.
The tailfin ensures the sampler aligns properly with the flow direction in the stream, guaranteeing the device enters the water with the correct orientation to collect accurate sediment samples.
Touching the water tail first promotes rapid orientation with the streamlines of flow, minimizing disturbance and turbulence around the sampler, leading to more representative sediment collection.
When the sampler is raised from the stream bed, the orifice lifts immediately due to the suspension design, preventing collected sediment from spilling out and ensuring the integrity of the sample.
While optimized for flowing freshwater streams and rivers with bed sediment transport, it is best suited for conditions within the design parameters, such as the specified opening size and weight, ensuring effective sampling.
This is a 18 kg (approximate) cable-suspended bed load sampler with 3" x 3" (76 mm x 76 mm) opening and 1.4 expansion ratio. A tailfin arrangement provides flow direction orientation and sliding collar allows adjustment of balance point based on stream flow conditions. The collar is set so that the sampler will touch the water tail first to aid in rapid orientation with the streamlines of flow. This suspension attitude also insures that the sampler orifice will lift up immediately when the unit is raised from the bed to eliminate loss of sample.
