FM112 | Flow Channel and Flume

Experimental flumes serve as valuable tools for both teaching and research, enabling the study and demonstration of essential open-channel flow phenomena on a laboratory scale. They offer insights into various aspects, including flow regulation through control structures and diverse flow measurement techniques. It boasts a closed water circuit and an experimental section. This section's side walls are constructed from tempered glass, ensuring excellent visibility during experiments. To maintain durability, all components in contact with water are corrosion-resistant. The inlet design minimizes turbulence when introducing flow into the experimental section. The flume's inclination is also adjustable, enabling the simulation of slopes and the creation of uniform flow at a consistent depth. A range of experiment-enhancing accessories, also available. These accessories can be easily and securely attached to the experimental section's base, allowing for a comprehensive set of experiments. The experimental flume is equipped with a comprehensive range of functions for measurement, control.
