Takuwa GWD2 Wire Sensor for Debris Flow Detection

In recent years, Takuwa GWD2 Wire Sensor for Debris Flow Detection  is occurred frequently by heavy rain, large earthquake, volcanic eruption and etc. In various regions, Debris flow is made from mixed soil, stones, water and woods, and its speed is 3m-20m/s (approx. 80km/h)

It is important to detect the occurrences of debris flow as quickly as possible to escape disaster safety and quickly. Consequently, this sensor is installed in the area where is expected occurrence of debris flows such as mountain streams, and it can use for caution and evacuation by telling about sirens and revolving lights, simultaneously with occurrence (detection).

Wire sensor is for detecting a debris flow directly by cut of a wire which is strung in the cross section of torrent. Detected signal can be output to the warning siren device for evacuation information.


  • Direct and secure detection of Debris Flow
  • Detected signal can be output to warning device for evacuation of downstream residents
  • Simple structure and high durability
  • Easy installation and maitenance


  • Wire Sensor possible to put out an alert of mountain stream to the site or the local residents by use of the Debris flow detection alarm device
