(1-800-827-6364) Subject: Re: Calibrating windmeters An aside... I do not use the meter to tell the wind... I use my meter to calibrate my eye and my ability to accurately determine wind without relying on any meter. I wish no dependency on any tool. If they fit in my pocket, it will be there to confirm my wind impression. If they do not break when I sit on it, it is the perfect meter. Wind is not a constant. Any meter with a decimal point and numbers to the right is just crap and unneccessary. Just my opinion. aoxomoxoa coreykite@aol.com = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Date: Tue, 1 Aug 1995 05:33:42 -1000 From: robert.pudlo@dbag.ulm.DaimlerBenz.COM (Robert Pudlo) Message-Id: <9508011533.AA01740@dagobert.dbag.ulm.DaimlerBenz.COM> Organization: Harvard University Office of Information Technology Subject: Re: Calibrating windmeters Alan wrote: >I have a turbo meter that consistently reads a couple of mph higher than a >friends turbo meter.

Some 6 to 8 month ago there was a bigger discussion concerning hand-held anemometers (if someone is interested, I could sum up the whole thing - just send me your email-adress). Here's part of my 2 cents worth: If you could get a calibrated anemometer from a friend, you could easily compare the two displays. If not (like me) take a bike with a speedometer (it should be well-cali- brated, however) and wait for a no-wind day. Then try to drive at e.g. 20 km/h holding the anemometer in one hand and watch its display. (You shouldn't try that in your crowded main-street on a saturday morning!) Maybe you could ask your local aerospace industry to get an hour in their wind simulator ... The bike-thing should work quite well as the speedometers are very accurate if set up correct. Hope this helps, Robert. ... who's back from two weeks of buggying and bodysurfing at the Bretagne, France. email me at robert.pudlo@dbag.ulm.DaimlerBenz.com = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Date: Tue, 1 Aug 1995 10:08:04 -1000 From: naus@xi.cs.fsu.edu (James Naus) Message-Id: <3vm1j4$sr0@news.fsu.edu> Organization: FSU Computer Science Department Subject: Re: Calibrating windmeters Alan Sparling (ajs@stairs.nw.att.com) wrote: : I have a turbo meter that consistently reads a couple of mph higher than a : friends turbo meter.

Then you can calibrate it to you car odometer, assuming your car odometer is correct. This is the closest thing to a controlled wind source I can think of. ;-) James = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
