Real-Time Hydrological Monitoring. Built for the Decisions That Matter.
When a storm moves over a watershed, emergency managers need accurate data — now. Not in minutes. Now. HydroLynx Systems manufactures the remote monitoring stations, data transmitters, and telemetry equipment that make real-time flood warning possible.
We’ve spent decades building flood warning and hydrological monitoring systems for the customers who can’t afford failure: federal, state, and local government agencies, water utilities, and international organizations managing flood-prone watersheds around the world.
ALERT2-Certified Equipment for Modern Flood Warning Networks
The ALERT2 protocol — the current standard for automated flood warning telemetry, governed by the National Hydrologic Warning Council (NHWC) — brings 4× faster data rates, collision-free TDMA transmission, forward error correction, and support for more than 65,000 monitoring sites. HydroLynx builds its entire product line around ALERT2.
Whether you’re building a new network from scratch, expanding an existing ALERT2 system, or upgrading legacy ALERT equipment, HydroLynx has the equipment and experience to support you at every stage.
What We Make
Packaged Stations
Turnkey ALERT2 rain, weather, water quality, and stream level stations — sensor, transmitter, solar power, and enclosure in one deployable unit.
Telemetry Equipment
ALERT2 data transmitters, receiver/decoders, radios, antennas, power systems, and accessories for building and maintaining complete monitoring networks.
Rain Gauges
Tipping bucket rain gauges and all-weather gauges designed for accurate precipitation measurement in remote, unattended field deployments.
Sensors
Wind, temperature, humidity, barometric pressure, solar radiation, water level, and water quality sensors for comprehensive environmental monitoring.
Who We Serve
- County and municipal emergency management and public works departments
- State hydrologic and floodplain management agencies
- Federal agencies including the U.S. Army Corps of Engineers, Bureau of Reclamation, and NWS cooperative networks
- Water utilities and irrigation districts
- International government agencies managing flood-prone watersheds
Why HydroLynx
In the flood warning industry, reliability isn’t a feature — it’s the baseline. Our equipment is built to perform in the conditions where it matters most: remote installations, severe weather events, and networks where a missed transmission can have real consequences.
We’ve been manufacturing ALERT and ALERT2 equipment for longer than most of our competitors have been in the market. That experience is embedded in every product we build.
