Model: OSC77FD530HF

Features

– The channel is designed for studying the hydraulic flow phenomena

Under Frame

– The channel bed is an invert which rests on an H-beam under frame
– The invert has screws at interval for vertical and side adjustment of the invert to ensure that the channel bed is strictly straight an level through out the full length
– The length of the H-beam is about 6m
– This simplifies site installation as there is only one joint and is easier to ensure alignment of the channel
– The H-beam is supported by a fulcrum at one end and adjustable height support at the other end

Slope Adjustment

– The adjustable height supports use twin-screw
– Each screw is driven by a worm and wheel gearbox with a common motor
– A slope scale is provided at one end of the flume

Side Walls
– For safety reasons, the side walls are made of tempered glass or clear acrylic
– The walls are supported at the interval by brackets with a screw adjustment to ensure that the channel wall is straight and vertical
– Further, a set of small adjusting screws along the edge of each glass plate for fine adjustment is also provided to ensure that the walls are vertical, parallel and straight through out the channel length

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 the 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 motorized
– Power out is available on the carriage

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 also provided in the head tank to further smoothen the flow

Head Tank
– The storage tank has adequate water to fill the full channel
– The standard storage tank is a stainless steel tank with a mobile ladder for model installation

Circulating Pump
– The pump seal is mechanical
– A geared butterfly valve is provided for accurate flow control

Flow Measurement
– A paddle wheel type flow sensor with two indicators, front and rear of the channel, is used for easy observation on flow adjustment
– A water meter is available as an option and may be used as a reference for flow indicator setting later

Model and Accessories

– All accessories and models have side seals to ensure no water seepage or leakage through the side of the models A wide variety of models and accessories are available as an option
