Under Frame
The channel bed rests on twin beam under frame which ensures static
loading deflections are kept to a minimum. The length of the beam is
about 6 m. Each section is shipped with glass side walls. This
simplifies site installation as there are only two joints and is easier
to ensure straight side walls throughout the length. To ensure minimum
deflection, the beam base frame of 18 m. is supported by a fulcrum at
the middle and adjustable height supports of both upstream and
downstream ends. The number of supports is more for 30m channel length.
Slope Adjustment
Each adjustable height support uses twin screws and with a system of
worm and wheel gear boxes and miter gears which are intern driven by a
motor. A slope scale is provided at one end of the flume.
Channel Bed
The channel bed is made of stainless steel with twin screw holes of
equal distance along the channel length to hold accessories or models to
the flume bed. These holes can also be used for pressure tapping to
measure pressure loss along the channel length.
Side Walls
For safety reasons, the side walls are made of tempered glass or clear
acrylic. The walls are supported at interval by brackets with screws for
vertical position adjustment.
Instrument Carriage
Top rails made of stainless steel tubes are attached to the top angle on
each wall of the channel. Screws supporting the rails can be adjusted
to ensure uniform height and in a straight line. A scale graduated in
mm. is attached along the full length of one top angle of the walls. The
instrument carriage is manually operated.
Head Tank
The head tank is made of stainless steel and its sides and bottom are
curved to ensure smooth flow into the channel. Perforated plates are
provided in the head tank to further smoothen the flow.
Storage Tank
An underground concrete storage tank is recommended as standard. This
tank is to be built by the user. However, above ground storage tank is
available at additional cost.
Walkway
A steel walkway with a checker plate floor and side rail is provided on
one side of the flume for ease of model installation and flow
observations.
Circulating Pump
The pump seal is mechanical. A geared butterfly valve is provided to control an accurate flow rate.
Flow measurement
A flow digital display is used. In the case of an underground storage
tank, a measuring tank with calibrated weir is available as an option.
The flow rate is controlled by a geared butterfly valve.
Model and Accessories
All accessories and models have side seals to ensure no water seepage or
leakage through the sides of the models. A wide variety of models and
accessories are available as option.
