Turbine Flowmeters, Part 2: Designs and Special Cases

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 axial turbines; insertion axial turbines; and multijet turbine flowmeters. Research into the use of axial turbine flowmeters for the measurement of two-phase (gas/liquid) flows is also briefly reviewed.
