Located north of the back parking lot.
Attributes
- Est. 2019
- 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).
