Dette punkt gælder ikke overvågningen af reagensniveauet i beholderen, der skal kunne finde sted under alle driftsforhold, hvis målingen er teknisk mulig (f.eks. under alle forhold, hvor et flydende reagens ikke er frosset).
This section shall not apply in the case of monitoring for reagent level in the storage tank where monitoring shall be conducted under all conditions where measurement is technically feasible (for instance, under all conditions when a liquid reagent is not frozen).
