Mobile Bed and Flow Visualisation Tank

The tank is manufactured from glass reinforced plastic and all components in contact with water are of non-corroding materials.

The working section has minimum dimensions of 2m(4m) x 610mm and the flow range is 0 3.5 litres/sec. Fifteen models and accessories are included as standard and a sheet of coloured glass allows rapid changeover from mobile bed to flow visualisation mode. All controls are housed in a portable console which includes a flexible cable and water safe connectors The tank is moulded from self coloured Oxford Blue glass fibre reinforced plastic with steel reinforcements to provide ridgidity.

It is manufactured in three sections; the inlet tank, the working section and the discharge reservoir tank. The sections are joined by flanged connections and despatched from the factory as a complete assembly. A drop-tight adjustable overshot weir with upstream sand trap is accommodated within the discharge tank. The inlet tank features a perforated baffle plate which spreads the flow evenly across the width of the table.

A removable glass sheet coloured blue on one side, white on the other, is provided to cover the sand bed when flow visualisation experiments are in progress. A pair of adjustable aluminium instruments rails are fitted to the top of the tank. These extend over the full length of the working section and one rail carries a positioning scale. The depth gauge supplied is used to measure the water level and to map the contours of the sand bed produced during excercises.

It is provided with a stainless steel hook and point and incorporates a Vernier scale enabling levels to be determined accurately Working area: 2 metres x 610mm or 4 metres x 610mm Max water depth: 120mm Thickness of sand bed 60mm Flow range 0-3.5 litres/sec Sump capacity 300 litres Accuracy of flow metering 1.5% of full scale deflection
