Abstract
A meter is provided for measuring the volumetric flow of a fluid in a conduit. The meter comprises a pair of turbine assemblies. Each of the turbine assemblies are adapted to have a speed of rotation representative of a volumetric fluid flow that is independent of the other turbine assembly. A flow randomizer is located between the pair of turbine assemblies. The flow randomizer is operable to eliminate substantially all flow effects of one of the turbine assemblies upon the other turbine assembly. Means are provided for transducing the speed of rotation of at least one of the turbine assemblies.
