My weather station.
Posted: Tue 25 Mar 2014 5:22 am
Here is some photos of my weather station. Nothing special, just a WH-3081 and a Nylex 1000 (250ml) rain gauge. The annometer and sensor is mounted to a ~4m treated pine post with the sensor mounted ~2m from ground level - a little higher than should be, but at this height it gives a uninterrupted signal to the base unit (loss of signal).
The main reason for the photo is for my WH-3081 rain gauge mod. Taking a couple of examples/mods from others here on the forum (thanks to those), I've made this simple and cheap mod to my rain gauge. It consists of a 50x100mm drain-pipe outlet, a 80mm diameter adaptor and a 135mm funnel (the smallest 'single' funnel I could buy without buying a funnel 'kit'). All-up cost was about AUD$25.00 from Bunnings (Australia).
The outlet was simply glued to the original bucket and sealed with a UV resistant 'salastic'. The funnel was then inserted into the adapter and sealed with the above 'salistic'. The funnel/adapter simply slips on and off the outlet - easy for cleaning and maintenance.
After a couple of weeks 'calibrating' (trimming) the funnel, it now measures ~85mm. At present, my modified rain gauge is accurate to +/- 0.3mm (or one bucket tip) of the manual gauge - with NO calibration required from within Cumulus (rainfall = 1.000).
Cheers,
Bruce
