Carel FLOS000000 Industrial Liquid Flood Detection Sensor
The Carel FLOS000000 is a highly sensitive, industrial-grade liquid detection sensor designed to safeguard critical equipment rooms, data centers, and HVAC/R environments against water leaks and localized flooding. Built within a durable, low-profile protective metal bracket chassis, this electronic sensor monitors floor levels or drain pans via integrated bottom-facing sensing electrodes. When water or any conductive liquid bridges the connection between its detection probes, the internal circuitry instantly changes its output state, providing a rapid warning signal to central building management systems (BMS), Carel programmable controllers (pCO systems), or supervisor alarms to mitigate expensive infrastructure damage.
Key Features
-
Highly Responsive Precision Probes: Utilizes conductive detection principles to register the presence of moisture or pooling liquids within moments of contact, minimizing fluid propagation risks.
-
Rugged Mechanical Shielding: Enclosed in a heavy-duty stainless or zinc-plated steel housing sleeve that protects the delicate internal printed circuit board (PCB) from accidental foot traffic, equipment impact, and industrial debris.
-
Seamless Controller Integration: Engineered to interface cleanly as a digital or analog input with Carel HVAC/R controllers, humidification systems, or external telemetry relays.
-
Low-Profile Surface Mounting: Features built-in elongated mounting holes on the outer metal flange, allowing the unit to be screwed down flush onto floors, condensate drain pans, or basement containment zones.
-
Continuous System Supervision: Operates with minimal power draw, providing constant, maintenance-free perimeter surveillance over high-risk liquid pathways.

Applications
-
Server Rooms & Data Centers: Placed underneath raised floors near precision air conditioning (CRAC) units to flag pipe bursts or coolant leaks before fluid contacts sensitive server racks.
-
HVAC Condensate Pan Monitoring: Fixed into primary or secondary overflow drain pans of commercial air handling units (AHUs) to prevent ceiling water damage caused by clogged drain lines.
-
Commercial Boiler & Chiller Plant Rooms: Stationed along perimeter walls or low points of mechanical rooms to alert technicians to pump seal failures or valve leaks.
-
Unattended Telecommunication Hubs: Serving as a vital remote safety input for standalone infrastructure enclosures vulnerable to rainwater intrusion or groundwater seepage.
