    How the InnovaMass Vortex Mass Flow Meter Operates Figure 1-1. In-Line Vortex Multivariable Mass Flow Meter Sierra’s 240/241 Series multivariable vortex mass flow meters use a unique sensor head to monitor mass flow rate by directly measuring three variables–fluid velocity, temperature and pressure. The built-in flow computer calculates the mass flow rate and volumetric flow rate based on these three direct measurements.
