SmartCone®

The SmartCone™, a variable area/beta ratio differential pressure cone meter, is a fluid flow meter that uses a measured differential pressure to provide a robust, accurate, repeatable and optimal cost measurement solution for both gas and liquid measurement.

Combine with a Dynamic Flow Computer to output

  • Flow Rate
  • Total Flow for Actual Conditions
  • Standard Base Condition & Customer Defined Base Conditions

The SmartCone™ meter produces a differential pressure which can be read by any standard differential pressure or multivariable transmitter.

SmartCone™

The meter is the first differential pressure cone meter to use artifact calibration techniques similar to orifice plate technology, which is inherent in the design. Each SmartCone™ meter has a verifiable geometry between subsequent manufactured devices using accurate and robust machined castings. It features the unique ability to offer a beta or area ratio change per diameter using interchangeable ARC’s. This allows the metered products’ flow velocity characteristics to be aligned correctly throughout the life of the meter.

The annular flow path between the pipe wall and the cone can be altered by attaching a discrete number of self-aligning and selfcentering Area Ratio Changers (ARC - highlighted in green). Multiple aligning surfaces of the ARC maintain the concentricity of the attached ARC to the integrated cone with the axis of the meter. Positive sealing between the integral cone and the ARC exists to eliminate leaks and unintended disassembly of the ARC.
