Abstract
This paper describes a detailed study, covering analytic as experimental aspects, about the effect on a commercial Woltman meter of different hydraulic fittings and configurations such as butterfly and gate valves. Firstly, a three-dimensional numerical simulation using computational fluid dynamics techniques (CFD) is used to calculate the alteration of the velocity profile by upstream fittings. Afterwards, the theoretical analysis undertakes the study of blade forces and torques generated by the fluid flow (Baker, 2000). Finally, laboratory test validate the analytical procedure proposed.
