Theory of thermal (hotwire) type Anemomaster

The air velocity sensor is heated and elevated temperature
(relative to the surrounding air) by means of control
electronics. The temperature compensation sensor sense
the ambient, or surrounding, air temperature and force the
velocity sensor to stay at a constant overheat above the
ambient. The circuit forces the voltage to be equal by means
of an operational amplifier. Air flowing past the sensor tends
to cool the sensor, thus driving down its resistance. The
amplifier responds by immediately delivering more power to
the circuit to maintain voltage equilibrium. Delivered power
is converted into electrical signal to display.
