Specifications

1. Laboratory flow channel is one of the most important tools available to the hydraulics or civil engineer whether engaged in teaching basic principles or researching solutions to practical problems. Many applications in fluid mechanics are associated with the flow of water through an open channel where the water has a free surface that is exposed to the air at atmospheric pressure.

2. The flumes are available in different lengths from 5 to 17.5 meters increasing in 2.5 meter increments. Armfield flumes are installed in educational and research establishments throughout the world.

3. A comprehensive range of accessories, and measuring instruments is available including discharge control, wave generation and a closed loop for sediment transport studies.

4. A self-contained glass sided tilting flume for fluid mechanics laboratory experiments, project work and research activities

5. The flume working channel is assembled from modular sections of 2.5m length. A wide choice of standard lengths are available from 5m upwards

6. The flume cross-section is 300mm wide by 450mm deep

7. A fabricated high precision stainless steel bed provides excellent strength and rigidity, eliminating the need for a separate under-frame.

8. No adjustments other than the jacking stations are necessary in order to set up and maintain the equipment, achieving typical bed deformations better than 1mm

9. Each flume incorporates a discharge tank fitted with an adjustable overshot weir and draught tube to avoid splashing and noise

10. An electro-magnetic flow meter is incorporated as standard 

11. A comprehensive range of optional accessories and instruments is available to supplement the
    capabilities of the basic flume

12. Closed-loop re-circulation is an option for sediment transport studies
