2.4.2 Fluid requirements
Gas - To avoid measurement errors, suitable measures
should be taken to make sure the line is full and the gas
in the line is kept below 1%. While the system may still be
able to measure with larger amounts, it has the potential
to affect accuracy. When gas is present, keep flow rates as
high as possible to help push the gas through the metering
section.
Particulate - To avoid measurement errors, suitable
measures should be taken to minimize solid particulate
in the line. Particulate should ideally be less than 1% for
accurate measurement.
Water in oil - Water and oil mixtures under 5% should not
affect accuracy as long as they are well mixed. Keep flow
rates high enough to ensure a well-mixed solution. Higher
percentages of water may be present, but this could affect
the accuracy of measurements.
Please consult Panametrics for any applications where
conditions are outside the above recommendations for a
more comprehensive application review.
2.4.3 Guidelines for installing pipe insulation
If pipe insulation is required:
• Install all insulation materials and accessories in
accordance with the manufacturer’s instructions and the
recognized industry practices. Adhere to the local code
where applicable to ensure that the safe and proper
installation will serve its intended purpose.
• Install the insulation material in layers, with smooth and
even surfaces. Allow adequate space (air pockets) around
all extended transducer buffer rods, conduit fittings,
junction boxes, and cables, for proper ventilation. Avoid
using cut pieces or scrap insulation when abutting the
sections being installed. Butt insulation joints firmly to
ensure a complete, tight fit over and around all piping
surfaces.
• Maintain the integrity of any factory-applied vapor barrier
jacketing on all pipe insulation, if applicable. Seal all joints
and seams, protecting the insulation against puncture,
tears or other damage.
