John Zimmerman at Sporty's told me smartphone anemometers
are niche products, but are gaining traction as they get better.
On the other hand, vane-type, hot-wire-type, and hood-type anemometers
and flowmeters are light and easy to carry and thus are widely used in the field.

Compared to the plasma anemometers
introduced in [1, 9,17], our method is a low cost, practical, and easy to realize one.
The slope of expression (6), d[A.sub.r]/d[R.sub.rc], seems to be directly related to the aerodynamic nondimensional coefficient of the cups, as very small differences in this coefficient were observed among the 42 calibrations performed on the 2 anemometers
In most cases, they find that the balancer is attempting to determine the air quantities and has a hot wire anemometer
of some sort.
which are used for weather forecast have a tolerance of +-0.3m/s to 0.5 m/s; these may be reasonably accurate anemometers
for weather forecast but such tolerance is not acceptable for wind turbine installation.
While there are several different kinds of anemometers
, the basic cup anemometer
(see Figure 3) is a standard fixture in the industry.
Wind speed can be measured with an instrument called an anemometer
