Core Technology: Multivariable Vortex

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.
