ESPLXD-ET Controller
SEEF and SELF Settings and Actions
To most effectively use FloWatch, you will want to first set your SEEF
and SELF thresholds and actions. SEEF stands for Seek and Eliminate
Excessive Flow and deals with how you want your controller to respond
when excessive flow is occurring, as might be the case with a mainline
break or a valve which is stuck in the open position. SELF stands for Seek
and Eliminate Low Flow and deals with what the controller should do
when low flow is present, as might be the case during a pump failure,
municipal water supply issue or when a valve fails to open.
