: Analogue output is based on the rated flow range at normal condition.

Displayed flow range is based on standard condition.

Therefore, the range of rated flow and the displayed flow are different..

At analogue output mode, the output analogue value varies by switching the mode (normal condition

↔ standard condition).

Use the formula below when the analogue output is used during standard condition.

Flow rate at normal condition ÷ 0.927 = Flow rate of standard condition
