MultiSmart Installation & Operation Manual
20.8 Estimating Duration to Overflow
When the well level is rising (pumps on or not, the inflow may defeat the pumps), the MultiSmart can
estimate the duration to overflow and display it until the level reaches the overflow level. This calculation is
dynamic and based on the dynamic rate of level increase. This time estimation is available in the DNP and
MODBUS points list so that it can be sent to SCADA.
To be able to use this feature, the flow module must be enabled in the MultiSmart. (If not enabled, refer to
Section 20.1).
Navigate to:
Under the flow General Settings button, check the Flow Enabled and Overflow Enabled check boxes and
set the % Level for Overflow.
To display the Duration to Overflow in the main screen browse to:
Select the Line in which the data is to be displayed from the left column and then select Duration To
Overflow from the right column and press Save. This value now appears in the bottom section of the main
screen display.
NOTE: When a probe is selected as the level device, the setpoints need to be at least 20 percent wide
so that the duration to overflow can be calculated.
