Vortex Flow Meter Overview

Vortex flow meters offer many advantages for flow measurement including easy installation without impulse lines, no moving parts to maintain or repair, less leak potential and a wide flow turndown range. Vortex meters also offer very low power consumption, allowing for use in remote areas. Additionally, Vortex meters are unique in that they can accommodate liquids, gasses, steam and corrosive applications. Vortex flow meters are also able to withstand high process pressures and temperatures.

Application

Different media solutions, such as liquid, or gas, can affect the capability of the vortex flow meter. Liquid - Liquids with heavy particle suspensions will wear down or clog internal parts, such as the bluff body, causing flow meter errors. Vortex flow meters struggle with liquids that have a high viscosity since they tend to dampen the formation of vortices and reduce the effective range. Particles and internal bubbles do not usually affect vortex meters. Most manufactures are calibrated for liquids of 1 cST viscosity. Anything above that will raise the minimum readable flow rate, reducing rangeability. Gas- Gas is compressible and changes volume when placed under pressure, heated, or cooled. For systems where gas is the primary media, the vortex flow media should have sensors which monitor changes in temperature and pressure in the system.
