WH40 min/max pole diameter
« on: December 30, 2022, 06:44:18 PM »
Hello,
I am to buy an Ecowitt WH40 rainfall sensor.
What is the min and max diameter of the pole?
Is 5mm suitable or a smaller size is suggested?

The small printed manual included with my clone ProTech version states: "The mounting assembly includes two U-Bolts and a bracket that tightens around a 1 inch to 2 inch diameter pole (package included a D32*H200mm stainless steel tube) using the four U-Bolt nuts". I have it mounted on a 50 mm (5 cm) L-shaped aluminium tubing sticking out from my balcony railing. The plastic top of the cavity in the WH40 could perhaps take about 1 to 2 mm more, so the 2 inch (50.8 mm) maximum is correct. I have seen pictures on this board with people mounting the rain gauge on everything from square wooden beams to plastic medium size tubes, or even screwed down on top of a fence - there are screw holes in the plastic shell. We all make the best of our own situation.

Many thanks for your reply sir, useful information indeed.
Id like to mount in a setup like you to my balcony.

We have quite stringent safety codes where I live to prevent things dropping on the heads of janitors, children etc so I used double backplates and sturdy "vagnsbultar" ('carriage bolts') to secure the setup on a rail post. Unsure how to post pictures on this site, so I've uploaded a closeup to DropBox. There can never be too many pictures of how we solve the mounting problems  :-)

Yes, thank you, I've seen the menu option but the restrictions are severe: "Restrictions: 8 per post, maximum total size 2048KB". One picture of 2 megabytes. That is old school. I would have to wip up conversion software on the PC to downsize everything my phone can produce, which is far from my expertise. What really makes me confused is that I've encountered several posts here with multiple high resolution photographs. No way the total was 2 megabytes there.

Really interesting.
Thank you.
At the moment I am a little bit confused how to mount in my balcony, so the more pics I see the more I can understand possible solutions.
For this, thank you man.
