Measures airspeed from  9 MPH to 350 MPH (15KPH to 563KPH)
If you need this where you live, I don't want to be there.....Oh wait, I do.... :-P

This picture was the first thing that came to mind:



If pilots are covering pitot tubes between flights to keep dirt/bugs out, how suitable are they for use in a 24/7 weather station which we all know are magnets for both...and also birds?

Probably passable in a handheld portable wind meter, though.....

I was thinking more about a "combined" wind VANE (direction) and ANEMOMETER (velocity)...basically an 'aircraft pitot tube wind vane'.

And, the reason pilots always cover/protect the pitot tube is because their LIFE depends upon it working 100% all the time, so it's protected until in actual use, ie: flight time.

I was flying with my dad when I was 10ish and the pitot wasn't working upon landing. I didn't get it then, but the trouble in my dad's face was not good, landing was over power lines on a short grass runway...all I remember is the stall warning horn constantly blasting, til he put it down. That was fun... :shock:

There was a fatal crash on takeoff from our local small airport several years ago.  Accident investigators found the "remove before flight" ribbon and pitot tube cover still in place.  #-o

Just speculating that the reason why pitot tubes are not commonly used in fixed-location weather stations is because they are vulnerable to being obstructed by environmental elements like bugs, dirt, water/ice, etc.....

Pitot "icing" was the cause of the B2 bomber crash at Anderson AFB on Guam.

Just received this info from Dwyer Instruments in response to my question about using a pitot-tube for "home" weather measurement:

Wow, does this remind me of being a kid again! I wanted one of these bad in the early 70's. Shocked they're still making this.
Thanks for the flashback!
