7.5 METRE FLUME
The FC300-7.5 Flume is 7.5 meters in length and 300 mm in width.
The flume has various different models available, so students have a wide choice of experimentation in open channel flow.
The flume has a built-in recirculating water supply connected to a digital flow meter for accurate measurements during experimentation. The flume has pressure measurement tappings at 0.25 metre intervals along the working section. These tappings can connect either to a multi-tube manometer or to a 32-Way Pressure Display. The 32-Way Pressure Display connects to TecQuipment’s VDAS® for real-time data acquisition.
The addition of the optional Level Gauge (FC300t) and Pitot Tube (FC300u) also connect to VDAS® to further increase the data acquisition capabilities of the flume. The Level Gauge and Pitot Tube require the FC300ic Instrument Carrier which runs on rails along the flume’s length and also provides traverse travel. Users can measure pressure and water level at almost any point within the working section. These measurements combined with the digital flow meter provides the potential for extensive analysis of open channel flow for research or advanced study.
Bed-load transport can be investigated using the optional FC300SL Sediment Loop. This ancillary provides a closed sediment circuit consisting of a sediment trap and feed mechanism which allows sand to be pumped from the trap to a feeder located above the working section between experiments.
The flume is made of transparent glass, precision-built to ensure parallel walls and a consistently accurate cross-section along its length. A sturdy steel square-section firmly supports the channel throughout its length. It has a floor-standing frame that supports the working section at a convenient eye-level position for students.
Screw jacks raise and lower the supports and the digital inclinometer gives an accurate adjustment of the channel angle.
A pump with a butterfly control valve, forces water up to flow settling chamber at the upstream end of the channel. This gives smooth, uniform flow, free from entry effects.
