Pilot-gemaal v1.2 — lessons learned

We needed both upstream and downstream pressures to measure the proper efficiency curve. The pressure drop was too high in an open-ended sewage collector pipe, which meant the downstream pressure was not at all representative of the calculated differential pressure over the pump. This gave stale / off values for the pump curves — and although the most-efficient control worked, it wasn't optimal.

These findings drove the modular v2 and v3 rebuilds. No own savings (validates machineGroupControl).
