Wireless Water Detection Puck

A slapshot for facility managers

Check Water’s Status Across Your Facilities

Sealed in a hockey puck made of nearly indestructible vulcanized rubber, the ALTA® Wireless Water Detection Puck Sensor is a novel way to monitor water presence or absence in a wide variety of facilities and locations.

With the perfect union of form and function, you can use the fully submersible, waterproof sensing device to face off against potential water damage by detecting leaks, flooding, and pooling. Or quickly sense the absence of water or other liquids in troughs, tanks, and containers. Place the versatile Water Detection Puck Sensor in virtually any facility area, including restrooms, kitchens, server rooms, boiler rooms, production lines, or under aging machines and systems.

The Puck Sensor is available in two colors—black or white. Generally, the traditional black puck design can be placed in virtually any location—industrial or commercial—to work behind the scenes gathering critical data. The white design offers the flexibility to use the sensor in facilities like hospitals, labs, and clinics where sensing devices and other equipment blend in with the décor.

The Puck Sensor’s inventive approach to supporting facility maintenance won a 2020 Vision Award for FM Building Services and Tools. Judges praised the sensor’s cost savings, efficiency, technological advancements, and contribution to tenant satisfaction.

Drop-in Monitoring

The sensor deploys in less than 15 minutes–drop it under problematic plumbing, leaky windows, or tanks and turn it on via a magnetic contact switch. Once water or liquid rises approximately 1.6 millimeters under the probe, the sensor’s probes detect the water’s presence. This triggers an alert that’s sent via text, email, or call. Similarly, you can configure the sensor’s settings to detect the absence of water or liquid and immediately alert you.

Monnit’s Water Detection Puck Sensor is an incredibly simple way to strengthen your defenses against water damage. Read more about this drop-in water sensor below.

Which Sensor is Right For Me?

  • Commercial AA-battery powered: Our most popular type is ideal for typical commercial & enterprise environments, such as server rooms. A 1,200+ ft. range readily covers most facilities.
  • CC-battery powered: Compact sensor is great for space-restricted areas such as control cabinets or cold storage.
  • Industrial: Sensor's weatherproof, NEMA-rated enclosure withstands demanding indoor/outdoor use, e.g., warehouses & production facilities.
  • PoE•X: Power over Ethernet sensors integrate with a building's PoE network; it can also be used with a standard Ethernet infrastructure & powered via an optional AC adapter.
  • MoWi: This discreet sensor uses your own Wi-Fi for networking and data transmission—popular for smaller businesses and facilities.
