Tilting Flow channel — MOE Lab Tender Details

Tilting Flow channel for Fluid Mechanics Engineering Lab Equipments

A glass sided tilting flume with fabricated all stainless steel bed.  
Completely self-contained and comprising the working section, moulded inlet and discharge tanks, a series of sump tanks, a pump, an electronic flow meter, a jacking system and a control console.
The channel section should be fully glazed with large clear panels of toughened glass coupled with careful design of the side support profiles to provide excellent visibility and allow flow visualisation of the full working height of the flume.
The overall strength and rigidity of the design should allow excellent stability figures to be achieved and must eliminates the need to provide adjusting screws or to perform periodic setting up of the flume to maintain its specification.  
No underframe or support structure other than jacks is necessary.
ï‚· Instrument rails are to be provided along the entire working length of the channel and a continuous scale calibrated in millimetres is provided along the length of one of the rails. Adjustable screws should allow the track to be set level and true.
Excellent velocity profiles must be able to be achieved in the working section by careful shaping of the inlet tank and by the incorporation of stilling and smoothing devices
Operating water levels are to be maintained by an overshot tilting weir located in the discharge tank.  
Water circulation should be by a centrifugal pump mounted beneath the channel, drawing water from a series of interconnected non-corroding sump tanks mounted on the floor and running alongside the flow channel. All interconnecting pipes and fittings must be of non-corroding materials.
The flow should be regulated using a manually adjusted valve. Flow rate should be measured using an electro-magnetic flow meter and displayed on a digital readout located on the control console.
The control console should be mounted on a pedestal and located in a convenient position for the installation, such that it is easily accessible and the flow rate can be read whilst adjusting the valve.  
The emergency stop button and the pump controls should be available
A computer control and data logging package should be provided ï‚· The  channel can be tilted using a jacking system - a single jacking station on 5m channel
A slope indicator should be provided.
