Basic functions
The NetaFlex™ 3G supports the following Nutrigation™ functions:
• Fully controlled dosing and mixing of fertilizers/acid with source water into a homogenous nutrient
solution.
• EC and pH correction of the nutrient solution (single or dual EC and pH control available).
Operating principle
Fertilizers and acid are injected into a tank, opened to the atmosphere; a homogeneous solution is
prepared in the tank before it is delivered to the field.
The open mixing tank method permits accelerated assimilation of fertilizers into the water. The result is a
perfectly mixed solution.
Service
The NetaFlex™ 3G utilises a modular construction making servicing a simple and prompt process.
The dealer keeps a small quantity of interchangeable components on hand, for replacement on site within
a few minutes.
Maintenance
To prevent failures and extend the life cycle of the NetaFlex™ 3G, regular maintenance must be carried out
by the user, such as periodic rinsing of filters and calibration of the EC and pH sensors.
Regular maintenance of the NetaFlex™ 3G is a prompt, low cost process requiring no special tools or skils.
