T echnical Guide DAN-LIQ-T urbine Meter-TG-0807 August 2007 Page 4 P A TENTED* FLOA TING ROT OR Flowing uid enters the turbine through the forward suspension. When it encounters the sharp angle of the cone, the stream is deected outward, increasing in velocity and causing a slight static pressure drop.

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.
T echnical Guide DAN-LIQ-T urbine Meter-TG-0807 August 2007 Page 7 RIMMED ROTORS FOR HIGHER RESOLUTION In the larger diameter Daniel Series 1500 Liquid T urbine Flow Meter (normally above 6” in line size), the resolution provided by a blade-type motor may be improved by the use of a rimmed (or shrouded) rotor .
