Application Cautions for Vortex Shedding Flow Meters
|
Application Cautions for Vortex Shedding Flow Meters Be careful not to operate the flow meter below the minimum linear Reynolds number constraint because the measurement will not be accurate. Do not operate vortex shedding and fluidic flow meters at low velocity or at low Reynolds numbers, because these flow meters will turn off and measure zero flow. Piping vibration can cause erratic and unreliable measurements with some vortex shedding flow meter designs, especially at low flow rates. Be sure to support these flow meters in a manner that reduces piping vibration. In addition, the flow meters should fit snugly into the piping. Forcing the piping into place can adversely affect the operation of some designs because abnormal forces can affect the flow meters sensing system. |
