Deeper funnel top and hydrobead
« on: October 17, 2017, 02:40:44 PM »
I've modified a few Coco gauges with deeper funnel and started using a spray called Hydrobead inside funnel area. This stuff is so slick it's amazing, you virtually get no beading in funnel area.
 
I started looking for a solution after comparing rainfall between the standard (non modified)  and extended (modified) funnel and was finding .01 less measured rainfall with the modified funnel because surface area was collecting more water droplets.

Haven't actually had a rain yet since the hydrobead just came in but my testing showed virtually no beading at all so every drop of water will get measured.

Reason for the extended Coco top is to prevent splash out which I've experienced many times when comparing a fully open coco gauge against fully assembled Coco gauge on heavy downpours and hail collection.

A few pics...I also sprayed inside the standard coco gauge along with both tipping buckets. Don't use a spray like this with the standard NWS 8" diameter gauge because you could contaminate the dip stick.
This Hydrobead spray may last up to a full year outside (have doubts on that claim) and also repels snow and ice, just a warning as you can see it puts a white glaze on surface.

Good thing the coco gauge only measures .01. Imagine if you were short .001! :-P
It never ceases to amaze me how we try to refine this hobby so every raindrop and every tiny little temperature change is accounted for. We have gone from splitting hairs to splitting the hairs we just split.
Randy I'm just razin you a bit because if I would have done what you did and noticed a difference I would have been looking for a reason why also.
Keep up the good work and I'm going to be looking for that product.

The .01 I agree isn't a biggy but it bugged me enough because I could see the little droplets sticking to the additional plastic plus the area where the extension molded together was collecting additional droplets.
They do say because every drop counts... =D> If the spray works and it does I'm going to use it.

Now just to be clear this .01 loss was only due to the deeper funnel. The deeper funnel itself will increase catch substantially with hail and heavy rain.

Video I saw using plastic. It works just like video with plastic coco funnel nothing sticks.

Thoughts about using this on an anemometer? Would it mess up the accuracy?

I ask because anytime we get a wet snow my anemometer collects the snow and eventually gets stuck, until it all melts off again.

Should work good. Really like it with raingauges.
