摘要: An impeller assembly including a motor that rotationally drives an impeller is balanced. The impeller assembly is balanced without physically indexing the impeller to determine the rotational position of the impeller while impeller is rotated. For example, the system does not employ an optical sensor, a magnetic sensor (e.g., a Hall sensor), a mechanical indexing sensor, and/or other sensors that physically index the impeller.

摘要: A device (12) that uses a temperature coefficient pre-calibrated for the device for measuring a flow within the device. The device includes a differential pressure sensor (80) configured to generate a differential pressure signal responsive to a differential pressure within a flow path (16) 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.

摘要: A method for calibrating a temperature compensation coefficient for a device (12) that utilizes flow. The device includes a flow path (16) and a flow restriction portion (14) in the flow path to create a pressure differential in the flow path. The method includes calculating a temperature compensation coefficient and obtaining a first temperature and a first differential pressure reading at a first time period before flow is generated through the device, and obtaining a second temperature and a second differential pressure reading at a second time period after flow is generated through the device. The method further includes obtaining a compensated differential pressure value based on the temperature compensation coefficient, the measured first temperature, the first differential pressure reading, the measured second temperature, and the second differential pressure reading. The method also includes obtaining the flow within the flow path as a function of the compensated differential pressure value.
