How the Pro-V Vortex Mass Flow Meter Operates Figure 1-1. In-Line Vortex Multi-Parameter Mass Flow Meter VorTek Series M22, M23, and M24 Pro-V™ Multi-Parameter Vortex Mass Flow Meters use a unique sensor head to monitor mass flow rate by directly measuring three variables–fluid velocity, temperature and pres- sure.
Page 14: Vortex Shedding Frequency
Chapter 1 Introduction Series M22/M23 Instruction Manual Vortex Shedding Frequency Von Karman vortices form downstream of a shedder bar into two distinct wakes. The vortices of one wake rotate clockwise while those of the oth- er wake rotate counterclockwise. Vortices generate one at a time, alter- nating from the left side to the right side of the shedder bar.
Page 15: Flow Velocity Range
Series M22/M23/M24 Instruction Manual Chapter 1 Introduction Flow Velocity Range To ensure trouble-free operation, vortex flow meters must be correctly sized so that the flow velocity range through the meter lies within the measurable velocity range (with acceptable pressure drop) and the linear range.
