3.4.1. Mechanical Inspection
Preferably, the original protection covers should still be intact. These may now be removed.
Before the spool piece is mounted in the pipeline the following must be controlled:
• The inside surface must be clean and dry. Use rags or similar to remove preservative.
Make sure no preservative is left in the transducer ports, as this may affect the
measurements.
• Check the flanges for damage. There must not be any damage to the gasket surfaces.
• Make sure that there is no damage to the meter, check the electronics enclosure,
cable glands, transducer cables, transducer end covers etc.
• Check that the positive flow direction indicated on the name plate is in the same
direction as the defined positive flow direction of the site.
• Use the correct type of flange gaskets, and make sure there is no damage to the
gaskets.
The support legs are threaded and may be removed after installation. They should be
stored and remounted before possible removal of the meter.
3.4.2. Installation of the Spool Piece
In most cases the spool piece is to be installed at a predetermined location in the piping
system. The size, material and flange type of the spool piece is manufactured to comply
with the existing piping. The size and type of bolts and gaskets must comply with the pip-
ing specifications. It is a condition for the installation that general knowledge about how
to install pipe work is held by the dedicated professionals.
Lifting lugs should be removed after installation in order not to be used if the MPU is to
be removed after years in operation.
3.4.3. Equipment and Tools Required
The following tools and equipment are necessary to perform a safe and correct installa-
tion of the spool piece:
• Crane or forklift
• Certified lifting slings
• Hydraulic tools for correct torque of the bolts
• Rags for cleaning of inside surface
• Necessary gasket lubricant
• Bolt lubricant
The size of some of the tools will depend on the flange type and size. Check weight and
pressure rating on the spool piece to get suitable equipment.
1. Use a forklift or a crane to place the meter in its position in the pipeline.
2. While a few bolts are fastened on both sides, check that the gaskets have entered
correctly.
3. Enter the remaining bolts.
4. Use the hydraulic tools and set the torque according to the pressure rating of the
flanges.
5. Pressurize the pipeline and check for leakage.
