Patent ID: 8798941

Claim:
A differential pressure sensor ( 105 ) for determining a differential pressure value, the differential pressure sensor ( 105 ) comprising: a selector valve ( 110 ) configured to receive a first pressure at a first location and a second pressure at a second location that is spaced-apart from the first location; a single-sided pressure sensor ( 120 ) coupled to the selector valve ( 110 ) and receiving either the first pressure or the second pressure; and a processing system ( 130 ) coupled to the single-sided pressure sensor ( 120 ) and configured to receive one or more first single-sided pressure measurements from the single-sided pressure sensor ( 120 ), subsequently receive one or more second single-sided pressure measurements from the single-sided pressure sensor ( 120 ), and generate the differential pressure value from the one or more first single-sided pressure measurements and the one or more second single-sided pressure measurements.
