PUMA and advanced flow calculation:
When specifying the physical design of the well, the PUMA controller subsequently calculates the following
data, which are available via the SCADA-system. It is therefore possible to get a load and performance profile
of the pumping stations, without having to invest in external measuring equipment for the individual
stations.
The PUMA controller finds the longest pump cycle for
each day, calculates the capacity of the pump based on
inlet time and pump-out time and saves this value as
the candidate of the day. After a custom number of
days, the candidates are evaluated, and the PUMA
control selects the most representative values for the
pumps' capacities. This allows the PUMA controller to
calculate the amount pumped out.
- Current outlet flow
- Out pumped quantity (Total, yesterday & today)
- Pump capacity
- Current inflow flow
- Inflow quantity (Total, yesterday & today)
The image is an example of a curve showing the current level (blue), outlet flow (green) and inlet flow (red).
Non-revenue water
The PUMA controller is also able to calculate the inlet
flow, which i.e. can be used to assess the amount of
non-revenue water in the system, as you have a clear
and correct load profile of your pumping station. The
curve to the right shows the direct relationship
between precipitation and the inlet flow to the
pumping station. Non-revenue water can in all
probability be found at this separately sewered
wastewater station. Since an increased inlet flow in this
example to the right relates to a precipitation event, in
this case it is either a direct diversion from the fortified
area or a faulty connection. Had the event occurred
