variometer
Vertical speed gauge
A variometer is an instrument that measures rate of climb or descent, essential in gliders and aircraft where pilots need to know whether they're gaining or losing altitude: The variometer showed we'd found a thermal.
In electronics, a variometer is a type of variable inductor consisting of two coils, one rotating inside the other.
