I know I have seen this somewhere but can’t for the life of me remember where.
I believe it is possible to increase the accuracy of the rain gauge on the WM-918 (possibly others as well) from 1mm to 0.1mm accuracy - by increasing the surface area of the collector unit.
Obviously this has to be a certain size, and then WD told of this.
So my questions:
-
What is the size/details of the increased funnel that is required.
-
When WD is told rainfall is now to 0.1mm does this only affect WD from the point in which this change is made ie it doesn’t affect records already recorded?
