1921 Flight 28 July 511/1 A new direction and velocity meter (yawmeter) has recently been constructed.

1947 Jrnl. Royal Aeronaut. Soc. 51 15/2 We imagine aerofoil and observer to be stationary and the aerofoil to be immersed in a stream of air of speed V normal to the span..the direction of the stream being made known to the observer by, for example, a yawmeter.

1969 Jrnl. Physics E 2 989/1 Calibration of the instrument as a yawmeter. Most of the tests on the instrument have been made near the outlet end of an open water channel.

1983 Jrnl. Physics E 16 231/1 (heading) A yawmeter for steady and low-frequency unsteady flows.
