The apparatus consists of a robust stainless steel settling tank that reduces turbulence, flowing into a 15 mm wide flow channel fabricated from transparent acrylic, together with various models, gates, weirs and hydrofoils. 

The equipment is designed primarily for use with Volumetric Hydraulic Bench which provides the necessary water supply, drain and volumetric flow-measurement facilities. The channel is fitted with dye injectors enabling the details of flow to be easily demonstrated and observed through streamlines. Alternatively, the customer may arrange their own water supply and flow-measurement facilities if desired.
