: Analogue output is based on the rated flow range at normal condition.
The displayed flow range is based on standard conditions.
Therefore, the range of rated flow and the displayed flow are different.
In analogue output mode, the output value varies depending on the mode (normal condition ↔ standard condition).
Use the formula below when the analogue output is used in standard conditions.
Flow range at normal condition ÷ 0.927 = Flow range at standard condition
