Model A-8	Model B-16

ELD designs and fabricates a wide range of demonstration channels. These channels are ideal complements to a course of study in fluids. After a discussion on hydraulic channel flow, ELD's demonstration channels bring the real thing right into the classroom environment.

Standard model, self-contained portable channels, may be easily rolled into the classroom to support lectures and demonstrations or into the laboratory for specific studies by individual students or groups. An optional model set is available for use with these channels. Models of numerous hydraulic structures, fluid meters and other devices may be easily installed and accurately demonstrated.

Typical, standard multi-purpose re-circulating demonstration channels consist of transparent wall channel sections, a head tank with adjustable, undershot gate, movable tailgate, reservoir, circulating pump(s), flow meter and flow control valves. A motorized jacking system adjusts the slope of the channel bed. Working channel sections are fabricated of clear acrylic Plexiglas, which provides leak proof joints with twice the impact resistance of tempered plate glass. SAR® (Super Abrasion Resistant) Plexiglas can be supplied, as an option, to provide additional resistance to abrasion. All other components that contact the flow are fabricated from non-corrosive materials including: fiberglass, PVC, bronze and stainless steel. These units require 110 VAC electrical services for operation.
