Chapter 2. Installation
2.3.1.3 Inner Diameter Matching
To maintain optimal product performance, the inner diameter of the upstream sections and flange should be within
1% of the metering section inner diameter at the flange. The downstream matching is not as critical but should be of
the same schedule and matched as closely as possible. In addition, gaskets should not protrude past the inner
diameter to disrupt the flow profile.
2.3.1.4 Vibration Considerations
The PanaFlow Z3 flow meter should never be exposed to prolonged or intense vibration. Pipeline vibrations at the
installation location should be avoided or eliminated whenever possible.
2.3.2 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 pocket for
convention) around mounting adapter in case of local mount and mounting adapter, junction boxes, conduit
fitting and cables in case of remote mount for proper ventilation hence heat dissipation. Allow enough space
around transmitter electronics for better heat dissipation and proper functionality.
•
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.
2.3.3 Fluid Comments
Gas - To avoid measurement errors suitable measures should be taken to make sure that the line is full and gas in
the line is kept below 1% of volume. 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 size of particulate in the
line. Ideally, particulates should be less than 1% of volume for accurate measurement.
Water in Oil - Water and oil mixtures under 5% should be measurable and will not affect accuracy if they are well
mixed. Keep flow rates high enough to ensure a well-mixed solution.
Fluid Cavitation - Fluids with a high vapor pressure may cavitate near the measurement point. This causes
problems resulting from gas bubbles in the fluid. Cavitation can usually be controlled through proper system design.
Please consult the factory for any applications where conditions are outside the recommended ranges for a more
comprehensive application review.
2.4 Making Electrical Connections
The PanaFlow Z3 utilizes the XMT1000 Transmitter module. For information regarding electrical connections required
for setup of the XMT1000 Transmitter, please refer to the included PanaFlow XMT1000 User's Manual.
WARNING!
Make sure all covers, with their O-ring seals, are installed and the set screws tightened
before applying power in a hazardous environment.
Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in Appendix D, CE Mark Compliance .
