Water Meter - Netafim NMC-JUNIOR PRO Installation Manual

SYSTEM CONFIGURATION PROCEDURE

7.5 Water Meter

• Ratio: Set volume per pulse of each water meter or auxiliary meter.
• Type: Define type of flow calculation:
 Standard: In this function valves which are operated in a group should be connected to the same water
meter.

Note: If a few valves configured to different water meters will be started simultaneously, the NMC-Junior Pro
uses the flow measured by the water meter connected to the leading valve.
Water source: The NMC-Junior Pro will sum or deduct flow measured simultaneously from a few water

meters. When choosing this function an additional column called "SUM" will appear, this column
enables to define which water meters should be summed and which deducted from the total measured
flow.

Note: Flow calculation type is a general definition for all water meters, therefore when changing type of water
meter for one of the water meters the type will be changed for all water meters.

Note: When setting flow calculation (water meter type) to Water source it is not possible to configure valves to
water meters.
• Sum: Define whether flow measured by each water meter should be added to the total measured flow or
deducted:
"+" Flow measured by this water meter will be added to the total measured flow.

"–" Flow measured by this water meter will be deducted from the total measured flow.


Note: Since flow cannot be negative, if the controller measures negative flow it will show zero.

Note: If all valves are set to "–" the system ignores the measured flow and will use the nominal flow (based on
the nominal flow).
