CF 流道 (截面: 80 x 300毫米)



Channel, through which water flows, of rectangular section with transparent walls that enable to observe all the experiments.




Channel, through which water flows, of rectangular section with transparent walls that enable to observe all the experiments. Water is taken from the storage tank by means of a hydraulic pump and, by the pipe, it is driven to the inlet tank, where there is a flow stilling device. After that, the water flows through the channel that discharges in the reception tank. Finally it comes back to the storage tank, completing the closed circuit.

To regulate the flow through the channel, there is a valve at the output of the pump.

To measure the flow there is an orifice plate flowmeter and a Venturi type flowmeter. The flow also can be measured with the flowmeter of the Basic Hydraulic Feed System (FME00/B).

A limnimeter (CFRM) is required to measure water level. Besides, a Pitot tube with tubes manometer board (CFTP) us required to measure velocity/flow.

The channel is assembled on two supports, with a system to control the inclination of the channel.

There is a wide range of available accessories.
