This is a 18 kg (aproximate) 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. This sampler uses a style #3 nylon mesh sampler
bag (sold separately).
