salve. ho aperto questo post per pubblicare i vari confronti trai vari sistemi meteo che sto facendo , prima di tutto vi mostro la postazione dove si trovano i vari sistemi [ You are not allowed to view attachments ] i sensori usati sono ecowitt ,ci sono i sensori standard (quelli a scatoletta) ed i nuovi sensori con sonda sht35 [ You are not allowed to view attachments ] gli schermi sono il meteoshield pro , il lastem il davis e la ws80 i sensori sonda sono nel pro e nel lastem, nel davis c'è un wh31 modificato per metterlo in verticale, nella ws80 cìè il sensore originale

Dovresti pubblicare in qualsiasi lingua sia la più semplice per te, in particolare quando pubblichi informazioni tecniche. Non preoccuparti delle persone che pensano che l'inglese sia l'unica lingua al mondo.

comunque ripensandoci bene , scrivo in italiano , io leggo i vostri post traducendo la pagina , potete fare anche voi lo stesso [tup]
dati di oggi ... confronto tra meteoschield pro lastem e ws80 , guardate intorno alle 16 che crollo di temperatura , senza che ci siano nuvole o aumento del vento #-o

That Meteoshield Pro seems really nice as it shows to make a huge difference. I never realized before as typical images just show the spiral from the side, but I can now see from the under part that it is actually a triple helix....I thought before that it was just a double helix. Very interesting design.
-
e si, il meteoshiel pro è davvero un gran bel schermo , secondo me il migliore per quanto riguarda i passivi , il lastem è uno schermo professionale , ma non è all'altezza del pro, hanno trovato la formula giusta con questa forma elicoidale e l'interno di color nero

Ciao Ivano,
ho avuto una Davis Vantago Pro per 15 anni. Putroppo ora l'ho dovuto gettarla.
Ho provato 2 modelli ecowitt. Le temperature misurate sono davvero "fuori" di 5 gradi anche.
Cosa mi consigli di comprare? Per rilevare temperature +/- di un 1 grado di tolleranza?
Vorrei usare weewx e non spendere più di 500 €.
il shield passivo della Davis col sensore temp della ecowitt mi sembra non da dei risultati accettabili, vero?
+4 gradi anche fuori?
Purtroppo non ho corrente fuori nel giardino, quindi non posso montare qualcosa con shield attivo.
Sono in Austria (-20 d'inverno / 30 d'estate).
Grazie.

ciao , il mio consiglio è 1) meteoshield pro ( schermo solare) della barani 2) termoigometro wh32 sht35 con sonda della ecowitt 3) gw1000 (gateway ecovitt) 4)wh40 pluviometro della ecowitt (molto preciso) ed infine il wh68 anemometro che rileva radiazione solare e raggi UV e con questo allestimento sei apposto e dentro le tue 500 euro , ci sarebbe da aggiungere la consolle ( se ne hai bisogno ) dico cosi' perchè essendo tutto wifi puoi vedere in qualsiasi momento i tuoi dati sia dal cell tramite l'app wsview che dal pc sul sito ecowitt.net , ma anche dal cell .... se vuoi risparmiare qualcosa (50 euro), puoi decidere di prendere lo schermo solare lastem che si discosta dal meteoshield pro mediamente di 0,4/0,5 decimi nelle 24 h .
per quanto riguarda il davis 7714 risparmi 100 euro ma siamo a differenze superiori ad 1 grado mediamente , nelle giornate di scarsa ventilazione e buona radiazione solare ](*,) l'importante è avere il wifi in casa :???:

be , sono esposti a sud/ovest , la miglior posizione per fare in modo che vengano colpiti tutto il giorno in modo omogeneo dal sole , i due schermi non si ombreggiano mai , al massimo può essere il palo che per alcuni minuti possa ombreggiare il pro , il lastem è impossibile il sole sta di dietro a quell'ora :?

The consistent performance of the Meteoshield Pro really does go to show that it's worth getting.

E si ,in questo momento il meteoshield pro è probabilmente il miglior schermo passivo in circolazione, le sue prestazioni in qualsiasi condizione meteo o luogo dove si mette sono sempre al top :-)

The thing that does impress me is the fact you put it literally anywhere and it gets accurate temps & beats the Stevenson screen in temperature accuracy. Amazing piece of work honestly.
-
I think the magic is in the spiral design. Hot air rises, therefore there is always a natural convection that occurs with the spiral design. The spiral design is what allows air to move. Every other radiation shield you see is just a sandwich of layered sections that trap the air. Other weather station manufacturers should take note.
-
Esatto , il suo punto di forza è la sua forma elicoidale, questa forma in sostanza lo rende come un ventilato, il vento si incanala e viene spinto dentro , ma l'altra cosa importante e l'interno formato da una specie di schermo di colore nero, che assorbe la radiazione riflessa , insomma davvero ben fatto e studiato in modo eccellente :-)
-
Someone should paint the inside of their Davis 7714 or Ambient SRS100LX with black paint and test. Of course they would need a control, with another one that was not painted.

eheheheh io ho già fatto questa prova però non ho usato il davis , ma un mio auto costruito che batteva il davis , ma npn c'è stato nulla da fare , quando c'era vento tutto ok , andava quasi al pari con il pro, ma in assenza di vento e alta radiazione solare , il distacco aumentava in modo importante 0,6/0.7 decimi di differenza , il nero sotto serve per la radiazione riflessa , ma per il vento il nero non ha nessuna efficacia, ](*,) , comunque un confronto nel prossimo futuro sarà ;inserire un sensore sonda ecowitt dentro il davis7714 e fare la parte di sotto dei piatti neri , per vedere che succede [tup]
-
Sounds good. I look forward to your tests. Thank you!
-
Interesting stuff, thanks Ivano!
-
Not surprisingly Ecowitt are working on a new radiation screen design and I hope that they will be looking closely at the Meteoshield design.
Probably be a while as they are very busy with new projects but at least its on the board!
-
Mandrake,
Did you send them the tip to make it spiral?
Ecowitt is just fascinating in how much they listen to their customers for product innovation and improvement.
-

That's very interesting and would massively improve the quality of their external temp readings. I guess the radiation shield will also cost a bunch less than the high quality ones from the competitors.
-
yes I also felt that there is something planned that will concern the shielding of the sensors, we hope because it is something that is missing from the ecowitt and extremely important [tup]

Ecowitt suppling good radiation shields for their temperature sensors would help them surpass Davis & become one of the top dogs in the industry personally. They are one of the only companies in this field that listen to customer feedback & they are on the way to the top.

giornata molto calda con una massima di 33.7 , ma sempre con l'immancabile vento da nord , a quanto pare sarà una costante per una decina di giorni altri comunque il lastem in queste condizioni mi piace come va con uno scostamento medio di 0.38 decimi non è male , ma sono soddisfatto anche della ws80 che fa la sua bella figura soffre un pò la mattina , ma poi si riprende bene ;)

I'd personally think that the WS80 would perform worse out of them all since it's mainly a wind sensor & I'd have temperature accuracy lowest of my priorities. Impressive none the less. Thank you for the tests!

Sì è vero chi ha la WS80 la usa per l'ottimo anemometro
ad ultrasuoni, però se invece di avere quel piccolo schermino per schermare il sensore , avesse uno schermo più performante , be sarebbe un'ottima stazione , non arriverebbe al meteoshield pro ma il davis 7714 lo batterebbe senza problemi , che poi guardando i grafici che ho pubblicato , già adesso va alla pari al Davis , ;) ha anche un gran vantaggio la WS 80 un'elevata reattività ,
-
Agreed on the WS80.
When I first received the pre-production model of the WS80 I really recognised that Ecowitt/Fine Offset are deadly serious at this game because it was such a step up from the standard sensor suite in terms of build and design.
In my mind there is no doubt that they aspire to surpass Davis in terms of quality and capability if you want it, whilst offering a relatively good base level to get started.

the WS80 is an excellent station, there is a project to improve it in temperature measurement, which consists in coloring the plates of the shield in the lower part of opaque black, from the first data, there is a good improvement, let's see if ecowitt undertakes this way

Hi Ivano
I have tried to look on all these great charts you are making - and thank you for that! =D>
But I have a little hard time reading them, maybe because I'm a beginner in all this weather thingy here :roll:
Can you, maybe just with a few words, tell what they say?
What are the most accurate?
What setup do you prefer?
Just translate it to words, for someone like me.
Thank you
-
On the most basic level to understand the temperature graphs what you see is the temperature curves of each sensor type inside of a given radiation shield. You can read the legend to match color with each sensor/radiation shield pairings. What you'll notice is that the Barani Meteoshield outperforms the other radiation shields by producing a slightly lower temperature curve graph line. The indication is that the other sensor/radiation shields run hot and do not provide sufficient protection from thermal radiation warming caused by the parts of the shield and the sensor case retaining thermal mass energy.

exactly as galfert explained, which is the best system? they are the same, however as regards temperature, humidity and rain, the position on the ground is more suitable, as regards the wind, the position on the roof is better, the graphs are easy to understand, just read the legend that is in each graph and it's done,

hi, I'm back after some time, I changed my stations, renovating and adding new screens, I added two metspec screens a RAD-02 and a RAD-14 in station 2 and they are in comparison with the meteoshield pro, inside as sensors, they are all WH31 / 32 EP by ecowitt, in the first station I added a ventilated davis h24 now they are like this:
station 1 [ You are not allowed to view attachments ]
station 2 [ You are not allowed to view attachments ]

as you can see in the graphs of station 1, there is a problem with the ventilated davis h24, the fan turns slowly, I think it is the solar panel that is very damaged, I plan to solve it in the next few days, for those wishing to follow these comparisons in real time, click on these links https://www.ecowitt.net/home/index?id=9393 (https://www.ecowitt.net/home/index?id=9393) https://www.ecowitt.net/home/index?id=21281 (https://www.ecowitt.net/home/index?id=21281) [tup]

day with sun but also clouds, in the first part of the day no or very weak wind (note the behavior of the screens in this condition) then the wind increased, and everything returned to normal, excellent performance of the 24-hour ventilated davis but also of the rad-14 (metspec) [tup]

solar day with no or very weak wind, and when the wind is lacking, I know pains the ventilated davis dominates the comparison in its position, the rad-14 is really remarkable in the first part of the day, it behaves almost like the windy, and accentuates the famous the pro's problem in those hours, the rad-02 is fine, the davis 7714 suffers enough, a very interesting day despite being ahead of the season =D> [tup]

today very interesting graphs, and makes us understand the importance of the wind component, today almost absent or really very weak, despite the fact that the solar radiation was low, surprising results the wind dictates the law and is normal in these conditions, but the two metspecs? but above all the rad-14 which reaches -1 degree from the pro? certainly nothing definitive, maybe next spring-summer will be the opposite, but .......

today spring day, the solar radiation begins to rise, the wind was weak, in short, a good day to put the screens in difficulty, the vp2 pro ventilated and the davis screen always ventilated with wh31EP inside are the masters, but also the rad -14 is fine, it seems to follow the ventilated as an excellent performance behavior of the rad-02 which goes in line with the meteoshield pro, the davis 7714 is fine, but in the hours with high radiation it suffers a little. [tup]
-
It seems to me like using the Ecowitt WH32-EP (SHT35) inside of the Davis 6838 (FARS) is a better solution than the Barani Meteoshield Pro....right?
-

in conditions of no or weak ventilation, definitely yes, with moderate or strong wind the ventilated goes like the meteoshield pro, a few tenths up, it is obvious that a ventilated is always more performing see the davis vp2 pro, but pay attention to the rad-14 of the metspec really does mark a breakthrough in passive displays
-
The Campbell Scientific RAD14 looks impressive as does the Barani Meteoshield Pro as far as passive radiation shields are concerned but for the price of the Davis 6838 FARS as all being relatively close in price I think the win goes to the Davis. I'm speculating. Just saying that if you are going to spend around the same amount of money then I don't see how the passive solutions can justify that cost.

in my opinion with the tests carried out so far, if I had to buy a screen, I would buy the metspec rad-14, it costs less than the meteoshield pro, and much less than the ventilated davis, but to be sure I have to wait this summer, to have the definitive confirmation of the his goodness
-
Well when I check pricing for the US I get the following.
$214 - RAD14 and I imagine that there is some additional shipping which I couldn't get easily?
$221.23 - Davis 6838 from Scaled Instruments + $24 shipping.
€200 = $240 - Barani Meteoshield Pro + €100 for world wide shipping!
Potentially the RAD14 could be cheaper if shipping is reasonable. But it will likely best case end up the same cost as the Davis (only $7 price difference, you can't call that cheaper...that is the same when you are talking lower $200 range). And I'm not sure if there is a better dealer in the US for the Barani, because €100 for shipping is retarded. If you take shipping out of the equation the Davis wins as they are all in the lower $200 range.

well yes, buying in america, yes if i had to buy the Davis ventilated in Italy, i would pay 498 dollars, if i take it on scaled between shipping and customs i would pay 375 dollars, and it would arrive after 30/35 days in this covid period, while the meteoschield pro is finished 310 dollars, while the rad-14 together with the rad-02 I paid 290 dollars including shipping, with the convention of meteonetwork, but the rad-14 normally costs about 200 dollars, the prices davis in Italy are madness, they cost a lot, and I still don't understand why, ](*,)

Very interesting how what is cheaper for me is not what is cheaper for you :grin:
I suppose the good news is that these are all good options.

Hi Ivano, I've been reading through this post. Thanks so much for your detailed documentation and analysis. I'm new to all this and have found your posts very informative.
I have a quick question - why would the ventilated radiation shields perform worse than passive ones in high wind? My intuition would have expected them to be the same.

hello, in ventilated screens the same amount of air always enters, i.e. that sucked in by the fan, while in passive screens the strong wind arrives directly on the sensor, and this gives an advantage that the ventilated one does not have, in the case instead the wind is absent, or very weak, the ventilated has an advantage as it has that flow of air that sucks the fan while the passives do not, and go into difficulty,

finally a sunny day and up to 11 with no or weak ventilation, in these conditions the gw1001 goes crazy. all the limits of the small screen come to the surface, the ventilated are the masters, but also the rad-14 has performances similar to a ventilated, excellent performance of the davis 7714 with wh31EP inside,
the rad-02 more or less follows the metpro- the lastem defends itself =D>

Hi, in order to be precise,
istn't it WN1900 (Weather station, No solar panel as per the Ecowitt acronym scheme) ? And not VN ?

Yes WN1900AE is written on the back of my console, I am a beta tester too.
The E at the end I believe is for Europe since it uses the 869MHz band.

Not sure about that - its usually the "A" which stands for 868 MHz - see https://www.wxforum.net/index.php?topic=40730.0, acronym scheme.
"E" is probably something else. Like "extra, extended, enhanced ..." as in WH2320E.

Great, Ivano ! =D>
Unfortunately the WN67 is a "diet" version of the WS69 (WH65) sensor array - I will check with Ecowitt if the T/H/rain gauge replacement set they offer is already of the new WN67 quality (assuming that that good performance comes from the material used).

good day to make comparisons between the various weather systems, excellent solar radiation ventilation on average 8 KM / H in the central hours, with fairly high temperatures, almost 35 °, excellent performance of Davis 7714 with the WH31 EP inside, very well also the 2 Metspec RAD02-14 always with WH31 EP inside, the ventilated davis vp2 pro suffers as well as the Lastem, hard day also for the WS80, very good instead the VN1900 (test), I just have to wish you good view of the graphs . =D> [tup]

we resume after the mid-August holidays with our comparisons, yesterday windy day, but with good solar radiation, as usual when the wind is sustained, the ventilated screens suffer a little, while the performance of the davis 7714 is to be emphasized, which with the probe sensor positioned as Davis recommends, it works great :), excellent performance even of the 2 rad 02-14 of the Metspec, even the ecowitts defend well =D> =D>

Haven't read the entire topic. Do you have a theory as to why the ventilated Davis performs so differently?
-
Haven't read the entire topic. Do you have a theory as to why the ventilated Davis performs so differently?
hello, when the wind is above 10 km / h the ventilated starts to worsen its performance, the reason is simple, the ventilated always sucks the same amount of air both with no wind and strong wind, while for passive screens with strong wind, they work better, as more air arrives on the sensor, when the wind is absent, or weak, the speech changes the ventilated ones work well and are unsurpassed, while the passives suffer, so before installing a solar shield, it is necessary to understand the microclimate of the installation area, if it is well ventilated all year round, there is no need to install a ventilated one, but better a good passive screen,
-
hi, look at how a ventilated davis vp2 behaves with the arrival of a storm, the response delay compared to a passive shielding is considerable ](*,)

can you rewrite the rain values ordered by position?

hi Zoomx, there is no pre-established order, the reference is the manual TFA without lid, yes the VN-1900 marked the same amount of rain as the VP2pro ,this comparison was made in conditions of heavy rainfall, with a rain / rate up to 205 mm / h ;)

let's resume this discussion with the advent of spring, many ask me how one screen or station is compared to another, which screen should I take etc etc .. the best way to dispel any doubts is to look at a graph where there is a direct comparison, obviously there are no certainties in this matter, sometimes the same equipment moved to another place can give different results, but in any case with a direct comparison between screens/stations, some differences stand out, I will use for compared to me a post recently finished, with the move from the roof to the ground, [ You are not allowed to view attachments ]
this year there are no Ecowitt or similar stations, only the WS68, maybe later I will add some, but the place is very little now, I want to make it clear right away that I have no interest in the various brands present in position, I don't sell and I recommend buying nothing, it's just a passion that I've been practicing for years now and I share it. chiunque abbia voglia di postare , lo può fare tranquillamente, a presto per i primi confronti

good afternoon everyone, let's continue with the comparisons, even if the climate is not exactly optimal, report dated 19-20/05/2023
days characterized by poor ventilation, the 19th with good radiation, while the 20th with lower radiation, ideal conditions for the davis vp2 pro vent, but also the rad 14 stands out in similar conditions ;) good vision to all

yes :grin: finally I approve let's continue the comparisons, report of 19-20/05/2023
ps/ and I'm surprised that no one has analyzed Toby's reports to see that there is something that raises questions 8-)

I saw something, but I was a little confused, as I see a 3rd generation pro with sht45 as a reference screen sensor, and another 3 pro with a sht35 inside that travels constantly below 0.2°/0, 3rd tenths, they would seem not to be aligned, and in any case I believe that making a comparison, you have to use the same sensor, however it could also be that you are doing something else instead of comparing, specific tests, or you try something, that by only seeing the graphs, It is not understandable

My Pro3 is equipped with a bi-sensor (SHT45 + SHT35) that allows to highlight the gain that the SHT45 brings.
The most important thing is not the SHT35 of the Pro3 but the FARS equipped with an SHT45 like the Pro3 strictly identical.

Good morning everyone, report dated 22-23/05/2023 location:
[ You are not allowed to view attachments ]
two good days, with high solar radiation and weak wind at times absent, temperatures begin to rise with peaks around 26/27°, the various systems have reacted well, no one has gone into difficulty, roughly in the most critical moments they have reacted very well remaining in instrumental tolerance, some jolts in the morning when the sun rises in the absence of wind, due to the reactivity of the screens, if we really want to make a ranking :lol:1)RAD 14 2)meteoshield pro 3rd generation and gradually the others, but let's talk about nothing ;)
good vision to all [tup]

Temperatures that start to be interesting, as well as solar radiation,note the trend of vp2 pro vent as the wind increases ;)for the rest everything in the norm, good vision to all
