Reply To: Mayfly version 0.5b data accuracy/validity

Hi,

After collecting nearly a year’s worth of data, it is clear that the depth sensor values are all over the place.  I’m attaching a file that shows the variability between the staff gauge and the mayfly depth sensor.  There doesn’t seem to be any pattern to the variation that I can determine.  I tried graphing the data to see if something would become visible looking at the data visually – and the graph didn’t make make the results any easier to understand.

Could a bad circuit board (existing corrosion) account for this – or would that just be junk data (not numbers) – or is this indicative that the depth sensor itself isn’t functioning properly?

Thanks for your time and help.
