• G01P 3/02 Devices characterised by the use of mechanical means
• G01P 3/26 Devices characterised by the use of fluids
• G01P 3/36 Devices characterised by the use of optical means, e.g. using infrared, visible, or ultraviolet light (G01P3/68 takes precedence; gyrometers using the Sagnac effect, i.e. rotation-induced shifts between counter-rotating electromagnetic beams G01C19/64)
• G01P 3/42 Devices characterised by the use of electric or magnetic means (G01P3/66 takes precedence; measuring electric or magnetic values in general G01R)
• G01P 3/62 Devices characterised by the determination or the variation of atmospheric pressure with height to measure the vertical components of speed (measuring pressure in general G01L)
• G01P 3/64 Devices characterised by the determination of the time taken to traverse a fixed distance
