How to Use Vortex Shedding Flow Meters

How to Use Vortex Shedding Flow Meters Vortex shedding flow meters measure the velocity of liquids in pipes such as water, chemicals and corrosives. Be careful in applications where flow measurement is required near the bottom of the flow meters range because these flowmeters turn off at low flow rates. The velocity at which these flow meters turn off is typically 1 ft/sec for liquids. In addition, vortex shedding can become nonlinear and turn off as Reynolds number is reduced. These flow meters can be applied relatively clean and corrosive liquids and will tolerate a reasonable amount of particulates. Materials of construction are generally limited to brass, stainless steel or plastics. These flow meters are available from 0.25 inch to over 6 inches in size. General applications are found in the water, wastewater, mining, mineral processing, power, pulp and paper, chemical, and petrochemical industries. Mining and mineral process industry applications include process water flows. |
