Introduction
The Filter Monitor continuously monitors the differential
pressure (pressure drop) across a filter and alerts the
operator of the need for element replacement when
any of three operating criteria are met:
1. Maximum elapsed time (service interval) before
change-out - operator alerted when user selected
time period elapses.
2. Maximum allowable differential pressure - operator
alerted when user selected maximum differential
pressure occurs.
3. Intelligence - operator alerted when the optimum time
to replace the element(s) has occurred. The Monitor
calculates this using the element type, the initial charac-
teristic pressure drop and historical pressure drop data.
