Claim Text:
1. A pressure measuring system for providing a corrected pressure that accounts for pressure sensor orientation, the system comprising: a pressure sensor comprising a diaphragm configured to deflect in response to pressure acting on the diaphragm, the pressure sensor producing a measured pressure signal in response to diaphragm deflection; an accelerometer configured to measure a component of gravity acting normal to the diaphragm and to produce an accelerometer signal indicative of the measured gravity component; and a processor operatively connected with the pressure sensor and the accelerometer to receive the measured pressure signal and the accelerometer signal, the processor being configured to determine the corrected pressure by applying a first compensation to the measured pressure to account for the effects of gravity on the diaphragm when the measured gravity component acts in a first direction normal to the diaphragm, the processor being further configured to determine the corrected pressure by applying a second compensation to the measured pressure to account for the effects of gravity on the diaphragm when the measured gravity component acts in a second direction normal to the diaphragm and opposite the first direction.
