High Low Alarm System
INTEGRA HLA
INTEGRA HLA is a high-low alarm system that raises high, high-high, low and low-low level alarms for each tank, on a local annunciator and in SCADA.
High Low Alarm System
What it does.
INTEGRA HLA watches tank level limits from ATG data or independent level sensors. When a level crosses high, high-high, low or low-low, the operator gets an alarm on a local annunciator and in SCADA, so receipts, storage and loading stay within tank limits.
Setpoints, measurement source and alarm response are set in a facility engineering review.
