Piping recommendations
WARNING
BURST HAZARD
Before pipeline cleaning and maintenance (“pigging operations”), remove straightening
vanes or flow conditioners.
Failure to comply may cause excessive pressure in the meter system, resulting in death,
serious injury or equipment damage.
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
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.
