  • Dry when not flooding
  • Mounted from 4x4 post

Installation Notes

Problems and Considerations (May 2020)

  • Sensor Height – mount at current height or higher (> 11.31’).
    • Cantilever arm must be level and static.
    • Unsure of 60’ flood height at this location.
    • Currently sensing concrete wall, mount out over edge of concrete pad for best readings.
  • RSSI issues – Removed indoor receiver from this location. poor RSSI since this location is far from receiver.
    • Mount transmitter and antenna as high as possible (use existing telephone pole?)
    • Mount transmitter and sensor separately.
    • Use 30’ sensor with longer cable.
  • Access issues – location is immediately adjacent to parking lot, but height and position over ditch poses problem.
    • Transmitter is virtually inaccessible as it is now.
    • If transmitter is mounted separate from sensor, both will need to still be accessible for battery changes, maintenance.
    • Ladder will not fit in concrete pad below sensor – spread too wide.
  • Sensing Cone Issues – the cone of detection is very wide at the ground level.
    • Sensor should be mounted at minimum height requirements to minimize size of cone.
    • Vegetation (knotweed) will need to be maintained.
    • Sensing cone least 37.91” (diameter of cone at ground level).
