Abstract
A device () that uses a temperature coefficient pre-calibrated for the device for measuring a flow within the device. The device includes a differential pressure sensor () configured to generate a differential pressure signal responsive to a differential pressure within a flow path () and a temperature sensor configured to sense a temperature near the differential pressure sensor. A differential amplifier amplifies differential pressure signals from the differential pressure sensor. A processor receives signals from the differential pressure sensor, amplified signals from the differential amplifier, and signals from the temperature sensor. The amplified signals are corrected based upon at least a predetermined temperature coefficient, and the processor calculates a flow rate based on the corrected representation of the differential pressure.
