Installation Notes
Problems and Considerations (May 2020)
- Sensor Height – mount at same height or greater (15.04’).
- Cantilever arm must be level and static.
- Mount out over center of ditch if possible.
- RSSI issues – must be kept at same height for best RSSI.
- Access issues – field adjacent to ditch is often saturated, access to site by foot.
- Cannot reach transmitter to change batteries without taking the post down, shouldn't have to take post down to access transmitter.
- Position of post adjacent to the ditch is awkward and unsafe when using a ladder to try and access sensor.
- Could move the location closer to 124th St for better vehicle access.
- Sensing Cone Issues – the cone of detection is very wide at the ground level.
- Be sure sensor mounted out from the post by at least 24” (radius of cone at ground level).
- Problems with flood debris getting caught on post and being detected within the cone even after flood waters recede.
