Real-Time ALERT & ALERT2 Networks for Life-Safety Monitoring
Flooding remains the most deadly and costly natural disaster in the United States. Automated flood warning systems give emergency managers the real-time precipitation and stream level data they need to issue timely warnings, activate emergency plans, and protect lives and property. HydroLynx Systems has designed and manufactured flood warning equipment for government agencies for more than two decades.
Our systems are built around the ALERT and ALERT2 telemetry protocols — the nationally recognized standards for automated flood warning established by the National Weather Service and maintained by the National Hydrologic Warning Council (NHWC). Every component we manufacture is designed for unattended, solar-powered operation in remote, harsh environments where reliable performance is critical.
A complete flood warning system consists of several integrated components working together to detect, transmit, and act on hydrological data in real time:
Remote field stations are deployed at critical locations throughout a watershed. Rain gauge stations measure precipitation as it happens. Stream level stations use submersible pressure transducers to monitor water levels at bridges, dams, and channel crossings. Weather stations add wind, temperature, humidity, and barometric pressure data for more complete situational awareness.
Telemetry equipment — including data transmitters, radios, antennas, and repeaters — carries data from remote stations to a central base station using the ALERT or ALERT2 radio protocol. Repeater stations extend the radio coverage of a network across mountainous or obstructed terrain.
Base station software receives incoming data, displays it on maps and graphs, triggers alarms when thresholds are exceeded, and distributes information to emergency management personnel, the National Weather Service, and the public.
HydroLynx manufactures complete, deployment-ready packaged stations that include all necessary sensors, transmitters, power systems, and enclosures. Our stations are designed to be installed in the field and operate reliably for years with minimal maintenance.
Models 5354/A2 and 5854/A2 — complete self-reporting rain gauge stations with ALERT2 transmitters, tipping bucket sensors, solar power, and weatherproof enclosures.
Models 5390/A2 and 5890/A2 — pressure transducer stations for monitoring water levels at streams, dams, reservoirs, and flood-prone crossings.
Models 5381/A2 and 5881/A2 — multi-parameter weather stations measuring wind, temperature, humidity, barometric pressure, and precipitation.
Model 50386P/A2 — store-and-forward radio repeaters that extend ALERT2 network coverage across difficult terrain.
HydroLynx equipment has been deployed in ALERT and ALERT2 flood warning networks operated by county flood control districts, state emergency management agencies, the U.S. Army Corps of Engineers, the Bureau of Reclamation, and international water management organizations. Agencies choose HydroLynx because our equipment is purpose-built for flood warning — not adapted from general-purpose data logging platforms.
Every HydroLynx packaged station ships ready to deploy. Sensors are pre-wired, transmitters are pre-configured, and enclosures are weatherproofed. Field technicians can install a station in hours, not days. And because all of our equipment is ALERT2-compliant, it integrates seamlessly with existing ALERT networks during phased upgrade programs.
Whether you are building a new flood warning network from scratch or upgrading legacy ALERT stations to ALERT2, HydroLynx can help. We work with agencies to design systems tailored to local watershed characteristics, radio terrain, and budget requirements.
Our sales engineers can help you design a system that meets your coverage, sensor, and budget requirements.
