NOTICE
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.
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 0.3 to 30 m/sec or 1 to 100 ft/sec).
• Space availability for meter lengths (to allow inlet piping customization):
Important
The bore of the mating piping should be within 1% of the meter inside diameter.
