Flow interface:
With very few settings, one can get the PUMA controller to perform a validated flow calculation.
Well data: Here, the design of the well, round or square, is selected, then either diameter or the dimension
of the sides in mm is entered. This determines the surface area, and the PUMA control calculates on the
basis of start / stop levels how much is pumped out during a pumping cycle. (For correct flow calculation, the
start level of pumps must be below the inlet pipe and the stop level of the pump must be above the
banquet)
Pump capacity: If you know the capacity of your pump, you can help the PUMA controller on its way by
entering it. Otherwise, the number of days entered in the next value field will elapse before data is available
for the capacity calculation
Days between capacity calculations: Number of days between the calculations of capacity. Typically set to 5
days. If the input value is equal to 0, then the PUMA controller will not perform capacity calculations.
Flow validation: Used in connection with a possible deviation in the measurements of the capacity
calculations. The entry is a deviation in%.
Example: If you enter 30 in the input field, the PUMA control will approve all pumping cycles that deviate by less than 30% compared
to the previous one. All deviations above 30%, it will reject and not include in the capacity calculations. If the input value is equal to 0%
then the PUMA controller will not perform capacity calculations.
Shark fin profile: If this value is set to 1, then PUMA ignores the pump control from the inlet profile when
making the capacity calculation for the pump. This function is typically used in situations where the inlet flow
is not constant, for example when pumping in from other stations.
Additional options:
It is possible to select 4 different maintenance functions. The functions are activated by ticking the individual
functions.
