Better resolution at rain gauge
I have made a patent for to have better resolution at rain gauge.Now at resolution at rainfall it is 0,25 mm from 0,5 mm
at La-crosse rain gauge,and i do a correction - 50 % decrease from the weather software,for to have the really rainfall.
The top of plastc box is twice of surface area of the La crosse rain gauge.I take 2 plastic boxes one big and the other
one smaller,i cut the bottom two of them ,i stick betwen them bottom with bottom with warm silicone.And after i put to the
top plastic box ,four pieces plastic from tent,and i stick them with warm silicone,for the rain to go inside at La crosse
rain gauge.And i put all of them over to La crosse rain gauge like hat.
Here it is the 2 plastic boxes ,little plastic for tent ,and the warm silicone.The dimension it is for small plastic box 9 cm x 18 cm x 6,5 cm high. And the big plastic box 9 cm x 18 cm x 13 cm high |
|
Here i have open one square hole at center of the bottom to one plastic box 4,5 cm x 11,5 cm |
|
Here i have open and two of them,square hole at center of the bottom of them 4,5 cm x 11,5 cm |
 |
|
 |
|
 |
|
| Here i have stick 2 plastic box together bottom by bottom,with warm silicone |
|
Here i have stick 2 plastic pieces for tent ,with warm silicone |
|
Here i have stick and another two plastic pieces for tent,with warm silicone and it is already |
 |
|
 |
|
 |
|
| Here it is from the down side |
|
Here it is from front side |
|
And here it is over to rain gauge like hat,on the roof |
 |
|
 |
|
 |
|
| After about two years i make another two of them,and for better protect plastic from the sun,i paint it with special white color for anti-UV sun radiation |

Rain gauge heater
I make another one modification ,heater rain gauge for to melt the ice,if there are very cold days with snow,
the snow sit over to rain gauge no melt,and do not have mm rainfall,and after 2--4 days it melt slowly slowly
from sun light and up temperature ,but so i loss the really mm rainfall from snow ,and so i make a modification
heater rain gauge with 2 halogen lights G4 12 volt 5 watts.I use electronic thermostat.
Here it is the AC/DC adaptor 12 vVolt 3 Amber waterproof box ,2 halogen lights G4 12 v 5 w ,cable,fuse |
|
Here it is the rain gauge ,lights base ,and conection for cables |
|
Here i mark the right position where must to put the lights base ,i will put the light near to the roof for to have this positon more heater |
 |
|
 |
|
 |
|
|
Here i open 3 holes from every side one big hole 5 mm diameter at centre for to pass the lights cable outside to rain gauger and 2 smaller 3 mm diameters for the screws to keep the light base |
|
Here it is the 2 halogen light inside to rain gauge |
 |
|
 |
|
 |
|
| Here i make a test all is fine |
|
The consumption current Amber it is and at 2 lights 0,8 Amber at 12 Volt DC |
|
Here it is the AC/DC adaptor in the waterproof case |
 |
|
 |
|
 |
|
|
Here it is ready ,i put warm silicone over to screws ,and at hole of cable |
|
Here i put a car thermometer with thin sensor over to plastic surface for to see the different temperature over to top of rain gauge,inside temperature it was 19,1 c and over to plastic surface rain gauge it was 36,8 c |
 |
|
 |
|
 |
|
| Here it is ready over to my roof ,the plastic box from outside rain gauge like hat ,it is for better resolution,and it keep more hot around rain gauge |
|
Here it is the electronic thermostat range temp + 5 c until +30 c,and the waterproof case |
|
Here i connect the cable at electronic thermostat |
 |
|
 |
|
 |
|
| Cable connect it is ok |
|
Here i make a test to electronic thermostat if it work well ,and all it is fine |
|
And here the same |
 |
|
 |
|
 |
|
| And here it is ready in my Stevenson screen box |
