FL 12.2 – Horizontal Free Jet Flow from a Tank

This equipment, has been designed for the study of all concerning the outlet of flow through orifices.


The water tank has adjustable height, reason why flow tests can be made in different conditions of pressure. The deposit has a scale that indicates the height of the level of liquid at every moment.

The equipment includes a panel with 8 indicating gauges, easily adjustable to the trajectory of the jet paths, and very simple to take the data.

The different nozzles are adjusted to the inner surface of the tank, obtaining the minimum possible disturbances.

On the other hand, the equipment has a built-in bubble level that allows us to know if the equipment has been correctly leveled, as well as vertically adjustable feet, to easily level the equipment.

The construction of the equipment in materials as aluminum or stainless steel, in all its metallic parts, guarantees the durability of it.
