To generate an alarm when flow exceeds 300 l/min, and reset it when the flow drops below 280 l/min, set Direction to Rising,
Activation Level to 300 l/min and Deactivation Level to 280 l/min.
About Negative Flows
While operating on negatives flows is possible, it is not recommended because of the potential confusion it can cause. A larger

Level must be a value less than or equal to the Activation
Level.
• If the direction is set to Falling, an alarm is triggered when
the flow drops below the
Activation Level. The Deactivation Level must be a value
