Filling line flow rate and pressure requirements
In order to enable the NetaFlex™ 3G operation, the following requirements must be met.
• Source water should enter the NetaFlex™ 3G at a flow rate equal to the maximum flow rate required
for the field.
If the flow rate at the inlet of the NetaFlex™ 3G is insufficient, the low level switch will be activated
and the NetaFlex™ 3G operation will be stopped.
