The first pic is what it looks like originally. 2nd pic shows the two bucket stop walls cut out and replaced with stainless machine threaded screws. 3rd pic shows view from the bottom and 4th pic reassembled (notice in this pic how much further the bucket needed to drop from the factory setting on the wall). I chose the screws inserted from the bottom so adjustments could be made without removing the bucket assembly.
Pouring 260ml of water (=1" rain) through countless times gave readings in the range of 40 bucket tips with screws almost all the way out up to 65 tips with them inserted fully.
I left the adjustments at 25 tips for just over 130ml (1/2" rain) of water for now to see how it does against the manual gauge with the next rain shower. Even left like this it's much closer than it was out of the box.
Great job Dan congratulation,I like the clever solution with screw for you going depth ,the tiping bucket,and it make little more time to go again up,for show the correct rainfall and you resolve the problem
I hope you put a nuts -safety at two screws,for it not go up-down easy,and you loose the correct tuning for the tipping bucket.
I will make other modification for this problem ,i will make smaller the surface at collector.
Any way i like your solution
Now i saw this topic ,if i understand well 2810 rain gauge have a small problem,it show more mm from normal analogue rain gauge (cocorahs) ?
Because i do not understand about inch but i know from mm measurements .Do you can tell me how mm it show more for the normal ?
Thank you
Keep up the good work
