Piping recommendations 25
Flow conditioning is recommended for best measurement results
• Honed or un-honed meter tube(s)
• Flow direction (unidirectional or bidirectional)
• Correct meter size selection - too low may cause poor flow stability (thermal convection
or too fast may cause erosion problems and resonance, cracks or failure of probes or
thermowells (approximately 0.6 to 12 m/sec or 2 to 40 ft./sec).
• Space availability for meter lengths (to allow inlet piping customization)
• Concentric alignment pins or flange concentricity technique considerations
For optimal flow measurement conditions, Daniel suggests the piping configurations below. Regardless of the
configuration selected, the user agrees to accept full responsibility for the site piping design and installation.
