The business of safety since 1956


High Water Warning System

Inclement weather and disasters often leave little time to properly warn drivers of the proper routes to shelters or safety. These weather conditions often obscure visibility of standard signage. BlinkerSign® LED-enhanced solar traffic signs provide notification and awareness of closed roads, evacuation routes or dangerous driving conditions. The advanced warning allows drivers to turn around and take alternate routes preventing backups. Each MUTCD compliant BlinkerSign® is built to weather harsh conditions and emergency scenarios.

Water level sensors for rising water are available

Optional High Water Sensors

Ground Level Fiber Optic Water Sensor

The fiber optic water sensor is a low-power method to activate systems in flood zones. The sensor housing is installed in the curb or banded to a pole and will trigger TAPCO BlinkerSign® or BlinkerBeacon™ flashing LEDs when water rises to a pre-determined level.

  • Dimensions: 3.7" x .5"
  • Adjustable water level action
  • Vented cabinet for moisture dissipation
  • Works in saltwater as well as freshwater

Pole Mount Water Sensor

The pole-mounted water sensor is easily installed at ground level to activate BlinkerSign® LED signs or BlinkerBeacon™ flashing beacons in flood zones. The tube-mounted sensor allows for a wide range of activation depth.

  • Eliminates need to cut concrete and fiber-optic cable run.
  • Widely adjustable water level sensor.

Optional BlinkLink™ Web-based Traffic Device Monitor & Control Software System

Monitor BlinkerSign® and other ITS device status from any web-enabled computer. Comprehensive management of all device settings, schedules and messages. Real-time information allows you to respond immediately to changing situations.
