The following is a description of a tilting manometer
designed by the technical staff of the National Advisory
Committee for Aeronautics to meet the requirements of a
manometer for use in the Wind Tunnel of the Langley Memor-
ial Aeronautical Laboratory.
T.,sgauge was designed to meet the requirements of a
manometer for use in connection with a static pressure
plate, to indicate the wind speed in the tunnel. These
requirements are: first, that the sensitivity of the
gauge may be made inversely proportional to the pressure
to be measured; second, that the gauge may be accurately
and quickly set for any desired pressure; and third,
that when set at the desired pressure the extent of var-
iation between the existing and the desired pressures
may be readily estimated. As the pressure measured be-
tween the static plate in the tunnel wall, and the airL____ _ ____
