The conclusion of this two-part series first addresses the unique design requirements of medical spirometers and propeller meters used to measure water flow. It then turns to the design details, operating principles, and capabilities of dual-rotor axial turbines; two-phase flow measurement with...more >>

Part 1 of this two-part article describes the applications,performance characteristics, mode and theory of operation, calibration, installation and maintenance procedures, and the design and construction of axial turbine flowmeters."
