Basic Configuration - Flow Alarm Menu

Low Flow Alarm Limit: Triggers an alarm if the flow drops below the programmed value (0 = alarm not set).

High Flow Alarm Limit: Triggers an alarm if the flow increases above the programmed value (0 = alarm not set).

Low Pressure Alarm Limit: Triggers an alarm if the supply pressure drops below the programmed value (0 = alarm not set).

Deviation Alarm Limit: Triggers an alarm after 60 seconds if the flow PV deviates from the flow SP more than the defined deviation (0 = alarm not set).

Under Pressure Mask: Triggers an alarm when the differential pressure is less than 3” W.C. of the supply pressure (On = alarm is active).

Valve Shut Mask: Triggers a “Shut” display when the flow is less than 10% of the maximum flow and there is pressure available. This alarm is used mainly on manual eFlo meters and in-line meters to alert the user that the meter’s valve may not be fully closed (On = alarm is active).

High Limit Mask: Triggers an alarm when the valve is fully opened to its maximum limit (On = alarm is active).
