Ultrasonic flow meter having flow conditioning arrangements for flow controlling in a linear fluid conduit

A fluid flow conditioning apparatus, comprising:

• a linear fluid conduit having a first tubular body defining a major axis and extending from a conduit inlet to a conduit outlet arranged opposite the conduit inlet, and configured with a predetermined flow geometry to define a linear fluid flow path along the major axis;
• a fluid inlet defining an inlet fluid flow path that is non-parallel to the linear fluid flow path;
• a first fluid flow conditioner comprising a second tubular body, wherein a first conditioner inlet comprises a plurality of ports defined radially through the second tubular body, and a longitudinal end of the second tubular body defines a first conditioner outlet, and arranged proximal the conduit inlet and having the first conditioner inlet in fluidic communication with the fluid inlet, and the first conditioner outlet in fluidic communication with the conduit inlet, and configured to:
• receive fluid flow through the first conditioner inlet along the inlet fluid flow path;
• condition, by the first conditioner inlet, fluid flow;
• and
• redirect conditioned fluid flow away from the inlet fluid flow path and through the first conditioner outlet along the linear fluid flow path along the major axis;
• a second fluid flow conditioner arranged proximal the conduit outlet and having a second conditioner inlet in fluidic communication with the conduit outlet, and a second conditioner outlet, and configured to:
• receive fluid flow from the linear fluid flow path along the major axis;
• redirect fluid flow away from the linear fluid flow path and through the second conditioner outlet along an outlet fluid flow path that is non-parallel to the linear fluid flow path;
• and
• condition, by the second conditioner outlet, fluid flow;
• and
• a fluid outlet configured to receive fluid flow from the second conditioner outlet.
