ATENG 11807 — Mobile Bed and Flow Visualization Unit (working section: 4000x610 mm)
The Mobile Bed and Flow Visualization Unit (working section: 4000x610 mm), “ATENG 11807”,
is mounted on a metallic structure with wheels, rigid and resistance enough to support the
weight of water and sand without suffering any deformation.
All components in contact with water are of non-corrosive materials.
Diagram in the front panel with distribution of the elements similar to the real one.
This unit is divided into three sections: inlet tank, working section (channel) and discharge
tank. These sections are assembled through joints in order to get a complete assembly.
Stainless steel inlet tank, with adjustable hermetic overshot. It is supplied with a control at
the upper side of the tank which makes it possible to change the slope of such overshot.
ATENG 11807 detail
The tank includes two perforated distributors and a perforated plate to spread the
flow evenly across the width of the tank. Inlet tank dimensions: 530 mm x 710
mm x 530 mm.
Flow channel, made of stainless steel, including two main rails along the working
section with millimeter rulers (longitudinal crosspiece).
Instruments carrier which has a sub-rail (transverse crosspiece) is supported on
the rails and allow to put a gauge. Two sand traps can be coupled to both
ends of the working section. Dimensions: 4000 mm x 710 mm x 350 mm. The
working section is 4000 mm x 610 mm, and max water depth is 120 mm approx.
Discharge tank, made of stainless steel, with overflow. It is divided into two parts,
the one closer to the channel enables the sedimentation of sand, using a trap,
whereas the second part enables the removal of the water which overflows from
the first part. Discharge tank dimensions: 850 mm x 710 mm x 530 mm.

Instruments carrier, which can be positioned over any point of the working
section.
Set of models included
Gauge designed to be mounted on the instruments carrier. It is provided
with a stainless steel hook and a point, and a Vernier scale.
Three water storage tanks, made of polyethylene, of approximately 250 l each
one.
It has a filter at the pump inlet to retain possible residues, a butterfly valve and
an overflow that connects the storage tanks.
