Core Technology: Multivariable Vortex

Measuring the Mass Flow of Gases, Liquids, & Steam

Vortex shedding flow meters have been in use for many years. The typical device is a flanged in-line unit. Most vortex meters measure only one variable (the velocity of the flowing fluid). Effectively, this makes the typical vortex meter a volumetric unit. While mass flow can be calculated for a constant density fluid, it becomes problematic for gases and steam. A multivariable mass vortex meter builds upon the current generation and offers improved accuracy, lower installed cost, and enhanced functionality, including multiple outputs of process conditions.

Benefits of thermal mass flow meters for gases:

  • Direct mass flow measurement of gases eliminates the need for temperature or pressure compensation
  • Accuracy +/- 0.5 percent reading; high flows 60,000 sfpm (0-305 smps); 100:1 turndown
  • Multivariable: Mass flow rate, temperature & pressure
  • Advanced four-sensor “dry sense” technology minimizes drift and enables field validation
  • Insertion version with hot tap capability for easy installation
  • Software applications for easy set-up, in-situ calibration, dial-a-pipe, and gas mixing
  • Digital communications suite
