A differential pressure sensor (105) for determining a differential pressure value is provided. The differential pressure sensor (105) includes 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.
