Using Multiple Liquid Level Relays in the Same Tank

FA273037

21 June 2021

Issue:
Can two liquid level relays be used in a single tank?  One would be for low level detection and a second for high level detection.

Product Line:
Control Relays - GIC Product

Environment:
US Product

Cause:
Product Application

Resolution:
Yes, in this application two relays could be used.  The second high level relay's probes will not interefere with the low level probes as the high level probes will only become wet when the water has hit its high point.  At this point it will not matter if the high level probe picks up the low level probe signal.  In either case it will detect liquid and change it's contacts over.
