Installation Notes

Problems and Considerations (May 2020)

  • Sensor Height – mount at current height (20’).
    • Cantilever arm must be level and static.
  • Safety Issues – location has a steep (~10’) drop off into the river.
    • Design must take into account river safety and ease of access of transmitter.
  • Access issues – location is immediately adjacent to road, but in a precarious spot at edge of bank.
    • If transmitter is mounted separate from sensor, both will need to still be accessible for battery changes, maintenance.
  • Sensing Cone Issues – the cone of detection is very wide at water surface.
    • Any interfering branches may need to be removed.
    • Sensor should be mounted out over the river as far as it is now or farther.
