Do you need to monitor fluid levels in addition to detecting plumbing leaks? Any of the Madison Company liquid level sensors found on this page can easily be added to – or used in place of – standard RDT and FloodMaster conductivity sensors.
Wire to pins 6 & 7 or 8 & 9 on the FloodMaster RS-096 terminal block for simple audible alarm/notification, or add to RS-080, RS-094 or legacy RS-360 systems for valve actuation. These sensors can be set in the field for Normally Open and Normally Closed dry contact operation, for High/Low level alarms, or for pump-on and pump-off control. Contact us for details on how easy it is to integrate this liquid level sensing capability with any new or existing RDT plumbing leak protection system.
