Hi
Results for July so far. Note the point that the manual site RG11 was modified. I was away for a few days so the manual gauge was only read when I returned so I have put in the 3 day total for the others.

Regards
Alan

I had a bit of rain today July 19, 2012. We are in a drought period here in the midwest. These counts are from midnight.

Here are my results

Cumulus via Davis Vantage Vue Tipping bucket - .28 in
Cumulus via RG-11 - 1.54 in
Dallas Tipping bucket - 0.59 in
RG-11 via 1-wire Dual counter - 0.788 in

The new beta logs though are more informative showing the double tips and the counter increments. I guess maybe a 2 for 1 count might work? It doesn't make sense that its a debouce causing the double tips as the 1-wire counter is not incrementing in the same fashion.

Cumulus counts: 1.54/2=0.77 inches 1-wire dual counter counts-0.788 which is closer and the two sensors are about 20 inches apart.



I'll have to save more buffer / watch the 1-wire counter some more. Probably do maybe run owfs/1-wire 9097 on one of the seagate dockstars I have sitting around to get some better counting. Been playing with these very small USB dual port 9097s using same technology imports.



Running most current beta of Cumulus. I still see the double tips in the logs. Numbers "appear" to be twice that of what the 1-wire dual counter is reading. That said though it looks that the Dallas tipping bucket is under reporting a bit. I have a graduated rain cylinder (plastic) that I can put next to the two RG-11's, Dallas Tipping bucket that I might do in the next days or so. I am also swapping out Davis Vantage Vue for another Davis Vantage Vue that I have; Davis Vantage Vue #2.
The Davis numbers don't make sense to me so #2 will be mounted closer to test area and connecting two Davis consoles shortly as one will read two Davis weather stations one at a time.

I'm beginning to like the idea of using the RG-11 just as a rain sensor "on / off" switch and continuing to utilize the rain bucket method of measuring rain. It does work much better than the sponge rain on/off Rainbird sensor. (that too is connected).

Hi
Results for the first 12 days of August. Somewhat mixed - it's hard to draw any conclusion.
The manual site RG11 still has the funnel modification. The Cumulus attached RG11 has the bucket size set at 0.36 mm.

Alan

I haven't had enough rain here to get any kind of benchmark at all.

That said I do see that the Davis Vantage Vue bucket counts have coincided with the Dallas tipping bucket counts.

The RG-11 connected to the 1-wire counter sometimes is almost synced and other times totally off.
(wind?)
I have not modified the RG-11 connected to Cumulus hardware yet and still see the 2 for 1 counts. (maybe just a calculation change factor would work for me?)

That said I am not using any sort of funneling and have the devices all within 1-2 feet of each other.

The above noted I have the RG-11's numbers going to different DB's. That said will broadcast xAP wise the RG-11's and the Davis Vantage Vue over to one DB such that I could graph the real time accumulation and put it on one graph.(chartdirector). The attached is just the Dallas tipping bucket using the HB 1-wire counter.

I do have one touchscreen display showing all four counts live on one screen via flash.

Steve, I am currently using the cumulus real time txt file to populate a small mysql DB. Is there an easy method to get the RG-11 data to my DB via the real time txt file? Am I going about this wrong though?

Just noticed that we had a bit of rain here yesterday and the RG-11 (unmodified) connected to Cumulus and the Davis Vantage Vue matched rain counts at .22 inches. I am current running 1043.

Hi

Results for August - some very spurious RG11 readings on the Cumulus RG11 at the end of the month. My first though was birds perching on the unit but the select-a-graph shows the readings occur when there is rain - birds would be much more random.
The two buckets performed quite well. The dummy reading and two other red entries used the manual gauge reading due to instrument or computer hiccups





Regards
Alan

ok have not worked out figures per day but have monthly totals for

july rg11 3.19 inches tip bucket 4.65 inches

august rg11 5.3 inches tip bucket 6.07 inches

not really sure what to make of the figures

My numbers were so different between the two RG-11's sitting only maybe 24 inches from each; I quit looking. The odd thing is that the Davis and the Dallas tipping bucket are also adjacent to each other on the same weather mast and these two tipping buckets were always in sync. That said I honestly don't know if I want to use the RG-11 as a digital tipping bucket. Maybe just an on/off switch for a rain sensor.

My conclusion too. At least now if the RG11 development / accuracy continues, Cumulus has the ability to read the data from it .

this is septembers results

i bought a manual gauge from the local garden centre mid august just to compare as i was not sure how accurate the tip bucket was


manual gauge 6.56 inches

rg11 6.82 inches

tip bucket 6.48 inches


still confused about results but not to much difference

will see what october brings

Hi All
I thought it had gone quiet on the RG11 front but it seems I'm not the only on still playing with the things.

So here are my results from September.
The manual site RG11 is still modified with the funnel and an extra tipping bucket has been added. A very well made mini weather station from Lidl - not PC loadable - only stand alone. At £39.99 with wireless wind and rain sensors incredible value.
That's the one I have called SH Bucket (It's on my summer house roof). The SH Bucket only started during the month so a red 9.3 entry is added to correct the early part of the month. The RG11's are not a million miles out over a period but in the short term very erratic. The red zeroes are when there were no readings. The Sept 31st line is there to give a part reading up to 9am 1/10/2012.


Regards
Alan

the trend i have noticed is that with light rain the rg11 over measures and heavy rain under measures,

this does fall in line with the info on hydreon's site about accuracy in tip bucket mode.

more readings from other users might help to workout what is going on.

ok for what its worth this is the October figure

manual gauge 5.96 inches

rg11 5.73 inches

tip bucket 6.09 inches

looking a bit better will wait and see what this month shows
