This is my set up.
About 2 hours of rain
Manual gauge 6.7mm
RG-11 7.4mm
FO tipping bucket 6.0mm
RG-11 (Cumulus) 11.2mm
Regards
Alan

Re: Hydreon RG-11 results
Hi
I thought it would be interesting to show the graphical comparisons. First is the Cumulus Select a Graph for the FO bucket (lower trace) and the RG11 attached to Cumulus and the second the two RG's compared. The profile of the RGCum matches the FO Bucket although expanded. At least the timing looks similar in all cases. Obviously there is no timing available for the manual gauge.

Alan

Re: Hydreon RG-11 results
Alan what sort of timescale was it for you ordering to receiving your rg11 unit? was just to give me an idea as to when to expect it so that i can then test it on the direct rs232 port to compare the results for the double tips

Hi
I think it was 4 days for the first one - the second was longer probably due to customs (2 weeks?) so anyone's guess.

Hi Alan,apenwith wrote:The profile of the RGCum matches the FO Bucket although expanded.
Well, not entirely. The first section (up to 10mm) does indeed correlate very well, especially since many users suggest that the FO gauge under-reads somewhat. But from then on, the FO registers 6mm and the Hydreon 18mm.
I believe that Hydreon admit that their gauge can over-read in some circumstances, particularly with the wind blowing raindrops across the "window", so it might be worth also displaying the windspeed (and maybe sunshine, etc.) to see if that affects the correlation.
It can also "report" the raindrop size to some extent, but that probably requires a rather more "intelligent" interface than the current DTR-DSR switching.
Cheers, Alan.

Re: Hydreon RG-11 results
Hi
What I meant was that the timing and shape of the graph was similar but I did say expanded by which I meant the RGCUM was over-reporting. I don't yet want to change the tipsize until there may or may not be a consistant correction. I agree it would be useful to use the windspeed as well but I have a problem in that the anemometer stops working in the rain - probably the mast top connection which I haven't had a chance to de-mount yet. The difference between the two RG's also needs investigation - but that's what the tests are for.
Regards
Alan

Re: Hydreon RG-11 results
Hi,
Has anybody else noticed the following paragraph in the downloadable RG-11_Instructions but NOT in the paper manual supplied with the sensor:
"For best accuracy tipping bucket applications, we recommend annual treatment of the rain sensor lens with Rain-X. The Rain-X prevents a condition where the RG reads high because water droplets stuck on the sensor get blown by the wind, causing high readings. With Rain-X, larger droplets run off." [Hydreon's bolding not mine.]
I wonder if that's a recent recommendation or something that's now been withdrawn. Note the following Rain-X "Product description" on the Amazon.co.uk website:
"Please be aware that it [Rain-X] is not recommended for use on plastic surfaces. ....... The product will last up to 60 days."
Hydreon refer to the lens as "injection molded" which I think implies that it's plastic, and they refer to "annual treatment". Is there an equivalent UK product (WD40 is said NOT to be similar)? Also, I note that reviews on the Amazon.com site much prefer the "Original" Rain-X to the later "glass cleaning" version of the same brand.
Cheers, Alan.

Re: Hydreon RG-11 results
Alan, from my following of the device this a new(ish) recommendation.
You can buy Rain-X at Halfords along with their own brand (cheaper) version, and other brands - I use it on my car windscreen.
