As above,any reason why windspeed reading slower than actual and wind direction changing direction slowly. Would low batteries in weather station be the cause,although it is solar powered? Thanks for any info.

When you say actual are you comparing your reading with another close by ? Height above ground and nearby buildings,trees etc can affect readings. The Met Office standard is 10m above ground on an open test site and there are correction factors if your anemometer is below this. Are you getting a low battery warning on the console ? My weather vane is moving like a good 'un at the moment, but the wind direction is showing S to SW, don't know what the sampling period is for wind.

I have just held my hand held anemometer by Davis anemometer. Davis Reading “0”mph handheld “4.5 - 2.9”mph. New battery fitted to ISS unit , so I think new Anemometer arm will have to be ordered!.

Just cut a bush down that was partly sheltering weather station only to find it has made no difference . But did get earache from the Mrs :banghead:

Innovation and tech in action at Cereals LIVE


There is nothing quite like seeing tech in action to understand how it works and how it can be beneficial on farm, which is why Cereals LIVE will be putting demos right at growers’ fingertips.

From state-of-the-art robotics, to autonomous tractors and electronic weeding, Cereals LIVE will have it all available in video demonstrations in the brand new Innovation and Tech Demo ring, says event director, Alli McEntyre. “It’s a brave new world for farming, with innovation driving sustainability and efficiency. Being able to see the most cutting-edge technology in action will give farmers an insight into where their businesses could be headed very soon.”

So what will growers be...
