OPW CIVACON 8851E Overfill Prevention and Ground Verification Controller
The OPW CIVACON 8851E Overfill Prevention and Ground Verification Controllers designed for API bottom loading applications on single and multi-compartment tank trucks at storage depots.
In the event of a possible overfill situation the 8851E output relay sends a signal to a Terminal Automation System, control valve or pump to shut-down the loading operation.
Should proper grounding not be maintained a nonpermissive signal, generated by the 8851E, interrupts the loading process immediately. This remote shutdown ability in combination with its
enhanced features makes the 8851E the best fail-safe rack monitor available to the industry today.
It is a direct replacement for the 8130 series.
