AX2200/AX2300 Instruction Manual Chapter 1 Introduction How the AX2000 Series Vortex Mass Flow Meter Operates Figure 1-1. In-Line Vortex Multi-Parameter Mass Flow Meter azbil Series AX2200 and AX2300 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 pressure. The built-in flow computer calculates the mass flow rate and volumetric flow rate based on these three direct measurements.
Chapter 1 Introduction AX2200/AX2300 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 other wake rotate counterclockwise. Vortices generate one at a time, alternating from the left side to the right side of the shedder bar. Vortices interact with their surrounding space by over-powering every other nearby swirl on the verge of development.
AX2200/AX2300 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. The measurable range is defined by the minimum and maximum velocity using the following table. Gas Vmin Vmax 0.5 in 0.75 in 1 in 1.
Chapter 1 Introduction AX2200/AX2300 Instruction Manual The Strouhal number is the other dimensionless number that quantifies the vortex phenomenon.
AX2200/AX2300 Instruction Manual Chapter 1 Introduction Minimum Back Pressure A minimum back pressure is required to prevent cavitation in the vortex flow meter when installed in liquid applications. Cavitation is a phenomenon wherein a liquid passing through a low pressure zone no longer can remain in the liquid phase and therefore partially flashes (or “boils”) into its vapor phase. The resulting two-phase flow degrades the liquid calibration accuracy.
Chapter 1 Introduction AX2200/AX2300 Instruction Manual Flow Meter Configurations AX2000 Series Vortex Mass Flow Meters are available in two model configurations: AX2200 In-line flow meter (replaces a section of the pipeline) AX2300 Insertion flow meter (requires a “cold” tap or a “hot” tap into an existing pipeline) Both the in-line and insertion configurations are similar in that they both use identical electronics and have similar sensor heads.
AX2200/AX2300 Instruction Manual Chapter 1 Introduction Line Size / Process Connections / Materials The AX2200 In-line model is built for line sizes ½ through 4 inch wafer or ½ through 8 inch flanged design using ANSI 150, 300, 600, PN16, 40, or 64 class flanges. The AX2300 Insertion model can be used in line sizes 2 inch and greater and is built with a compression fitting or packing gland design using 2 inch NPT, or 2 inch flanged connections (ANSI 150, 300, 600, PN16, 40, or 64 class flanges).
