Communications infrastructure
Manholes, handholes, cable vaults, and other normally dry spaces where water intrusion can threaten critical equipment.
Quantum Visibility Systems LLC
Bring hidden conditions into view. We develop sensing solutions for infrastructure that is difficult to access, inspect, and connect.
Illustrative sensing concept. Not a live monitoring interface.

FloodTube is a battery-powered cellular water-intrusion sensing device. It is designed to alert operators when water appears in normally dry locations—without requiring site power or Wi-Fi.
We are seeking pilot and development partners to help evaluate real-world deployment, reliability, and operating conditions.
Discuss your application →Position or mount the device so its sensing contacts monitor the area of concern.
Water touching both sensing contacts completes a circuit and triggers detection.
Notify operators so they can assess the event and respond. Delivery depends on cellular coverage and deployment conditions.
Potential applications
Each environment presents its own challenges. Pilot evaluations help determine where FloodTube can provide practical, dependable awareness.
Manholes, handholes, cable vaults, and other normally dry spaces where water intrusion can threaten critical equipment.
Mechanical rooms, equipment rooms, and raised-floor areas that can benefit from an independent water-alert path.
Facilities and asset locations where bringing in power or local Wi-Fi is impractical, subject to suitable cellular connectivity.
One company. A broader vision.
Quantum Visibility Systems is building toward a family of devices that make hidden infrastructure conditions visible. FloodTube is our first step.
Future sensing concepts may extend that awareness to unauthorized access, humidity, and other environmental conditions.
Future concepts are not currently offered as validated products. Environmental suitability and battery endurance remain subjects for further testing.
Pilots & partnerships
Tell us about your asset, the condition you want to detect, and the challenges with your current inspection process. Let’s explore whether a FloodTube pilot is a fit.
