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).
