Argon Lines in Plant
High Purity Gas Plant
Liquid Nitrogen Plant
Offgas in Plant
Natural Gas Lines in Plant
Plant Air Lines

Application Considerations:

Digital Vortex Flow Meters provide a robust measurement for the process industry. Typical applications listed above have been proven with thousands of successful applications Worldwide. When considering a Digital Vortex Flow Meter for an application, keep in mind the following application requirements –

• Orientation of the Flow Meter in the process line should be specified
• Piping for the installation should be secure without a high resonant frequency
• Typical installations can require 20 Upstream Diameters and 10 Down Stream Diameters
• Single Phase Flow is required
• Full Pipe of the process flow media is required
• Little to no particulate in the process media (not intended for slurry applications)
• Installation downstream from a valve which is ‘cycling’ could provide false readings
• Changes of Temperature Values away from the calibrated range
• Changes in Pressure Ranges away from the calibrated range
• Changes of Flow Values away from the calibrated range
• Sufficient Flow to provide enough velocity to maintain a constant vorticity past the Sensor
• Proper installation and electrical procedures to insure no leakage of water into the electronics
• Proper installation including the ‘gasketing material’ between flanges and piping
• Avoid the possibility of using the Vortex Meter for other than its intended of Flow Measurement
