David,
You can also measure the rainfall amount by weight.
1cc of water weighs 1 g (strictly at 4C, but close enough at normal
surface
temps).
For a 5 inch gauge, devide the weight of collected water measured in
grmmes
by 12.6677, to get the rainfall equivalent in mm.
Don't forget to measure the container empty first, or when dry, and of
course, make sure your scales are accurate to the nearest gramme.

Interesting solution Bernard, thanks for that. I might try it later as there
are some large drops just appearing on the window.
