This unit is used to visualize the profile of a water jet. This apparatus allows students to measure the Decrease in flow, contraction of stream and energy losses. Additionally, the contraction coefficient can be determined as a characteristic for different contours. The experimental unit includes a transparent PPI tank, a point gauge and a panel for visualizing the jet paths. An interchangeable nozzle is installed in the tank’s water outlet to facilitate the investigation of various openings. Four nozzles with different diameters and contours are provided along with the unit.

To visualize the trajectory, the issued water jet is measured via a point gauge that consists of movable steel rods. The rods are positioned depending on the profile of the water jet. This results in a trajectory that is transferred to the panel. The tank contains an adjustable overflow and a scale. In this way, a precise adjustment and accurate reading of the fill level are possible.

The experimental unit is positioned easily and securely on the work surface of the EDC-FM-100 base module. The water is supplied and the flow rate measured by EDC-FM-100. Alternatively, the experimental unit can be operated by the laboratory supply.
