Flow controllers The graph to the right shows the flow rate curves of a flow nozzle with a 45-mm diameter and a RDM1020 controller (see page 5) for a maximum flow rate of 8...

The water intake at the surface allows highly precise regulation (+ or – 5%) (see curve to the right). It can regulate flow rates from 5 to 170 l/s for a maximum water height of 2 m and it can be installed on outlets with a cross-section from 100 to 350 mm. It is very suitable for installation in a basin before...
