T echnical Guide DAN-LIQ-T urbine Meter-TG-0807 August 2007 Page 6 TURBINE METER ROTOR AND BEARING DESIGN The primary differences in turbine meter technology are in the design of the rotor and bearings. The rotor is an assembly of up to twelve (in some designs this number is greater) blades locked into a hub, which rotates on a bearing or bearings.[...]
