HyQuest Solutions’ bed load samplers are designed to sample sand, silt, gravel or rock debris carried by a stream on or immediately above its bed. The BLS30 and BLS48 cable-suspended bed load samplers are used in natural streams for carrying coarse sediments.
The Columbus pattern torpedo shape used in stream gauging weights has been adopted to reduce drag. The body is all welded stainless steel construction, complete, with a tail ﬁn arrangement to provide ﬂow direction orientation and a sliding collar to allow adjustment of balance point based on stream ﬂow condition.
The sampler is attached to the winch cable connector by the adjustable collar. The collar is set so that the sampler will touch the water tail ﬁrst to aid with rapid orientation with the streamlines of ﬂow. This type of suspension insures that the sampler oriﬁce will lift up immediately when the unit is raised from the bed to eliminate the loss of sample.
Samples are collected in a polyester mono ﬁlament bag of 0.2 mesh to A.S.T.M. speciﬁcations for uniformity, resistance abrasion and wear. It will not absorb water.
