In early hang gliding, variometers were not needed for the short flights or flights close to ridge lift . But the variometer became key as pilots began making longer flights.

The "'Relative Netto Variometer "'indicates the vertical speed the glider would achieve IF it flies at thermalling speed-independent of current air speed and attitude.

A variable capacitor ( or sometimes a variable coupling coil called a " variometer " ) was used, with a knob on the front panel to tune the receiver.
34.
Newer variometer designs directly measure the static pressure of the atmosphere using a pressure sensor and detect changes in altitude directly from the change in air pressure instead of by measuring air flow.
35.
Typically the audio tone increases in frequency as the variometer shows a higher rate of climb and decreases in frequency towards a deep groan as the variometer shows a faster rate of descent.

The designs described above, which measure the rate of change of altitude by automatically detecting the change in static pressure as the aircraft changes altitude are referred to as " uncompensated " variometers.

He invented the total energy variometer in 1939, used in soaring planes, and is the co-inventor of an early scheme for magnetically contained nuclear fusion, patent application, 1941.

There is an increasing trend for advanced variometers in gliders towards flight computers ( with variometer indications ) which can also present information such as controlled airspace, lists of turnpoints and even collision warnings.
