Lasse Ledet, Grundfos Grundfos arbejder i disse år på at implementere digitale tvillinger på deres pumper. Denne form for digitale tvilling er således en operationel digital tvilling på produkt niveau. Formålet er at sikre at pumperne ikke degraderes over tid, og vha. den digitale tvilling forudsige vedligehold.
