25SEP Experimenting with new river level sensor

More

The current River Level sensor is differential pressure (weight of water minus weight of atmospheric air) and the current Anabranch Level sensor is sonar (time of return to water surface by ultrasound signal). Both have their issues.

I am currently fiddling with a 24GHz radar sensor (time of return by microwave signal), with mixed results so far. It is supposed to be more impervious to environment, at the cost of lower resolution.

Work in progress.

05SEP

Will try to resuscitate it once again soon sigh.

08AUG

The sensor is back as close as I can get it to its original position, so you should not need significant re-calibration to map it to your situation.

With TLC, repairs and threats in equal measures, the old Aquagauge breathes again. I don't know how often I can bring it back…
07FEB River Level sensors changed

More

The level is not the depth, though it is related. The level is relative to some fixed point, not necessarily the river bottom (which moves).

Anabranch sensor: A new ultrasound-based River Level sensor has been deployed, affixed under my new footbridge (old bridge washed away in flood). This measures level of river on my side of island.

Merged sensor: The old pressure-based River Level sensor (transmitter nearly washed away with old bridge) has been re-positioned 30 meters downriver from island. This measures level of whole (merged branches) of river.

Old "river level" measures are nearly the same as the Anabranch level.
