3. INSTALLATION
3.3.5 Nominal Diameter 500 mm (20
in.) to 2600 mm (104 in.), Flange
Type
IMPORTANT
Use bolts and nuts in compliance with the flange
ratings. Be sure to choose a gasket with inner
and outer diameters that does not protrude
inside the piping (refer to Table 3.3.13). If the
inner diameter of the gasket is too large, or outer
diameter of the gasket is too small, fluid leakage
may result.
(1) Mounting Direction
Mount the flowmeter so that the flow direction of the
fluid to be measured is in line with the direction of the
arrow mark on the flowmeter. It may be especially
difficult to move large size flowtubes after bringing
them into the pit. Check directions before bringing.
IMPORTANT
If it is impossible to match the direction of the
arrow mark, the direction of the electrical con-
nection can be changed (only for size 500 mm to
1000 mm). Refer to Section 5.1 to do this
properly.
In case the fluid being measured flows against
the arrow direction, refer to the parameter J20:
Flow Direction in the user’s manual of the
AXFA11 Magnetic Flowmeter Remote Converter
(IM 01E20C01-01E).
(2) Carrying Flowtube
90 ° degrees or less
Fig3.2.18.eps
Figure 3.3.6 Lifting Flowtube
CAUTION
• When lifting the flowtube, use the lifting rings
(eye bolts or shackle).
• To assure safety, keep lifting angle less than
90 degrees as shown in Figure 3.3.6
• If the size is 1600 mm (64 in.) or larger, use
the eye bolts or eye nuts at all four of the
locations simultaneously and lift the flowtube.
Avoid lifting it from only one location or use
only two locations and lift it at 45 degrees.
• Do not shock the installation foundation bracket
when installing the flowmeter as the bracket
may be damaged.
(3) Positioning Flowtube
Bring in the flowtube, place it in the bracket and use a
jack to correct position it for height.
IMPORTANT
Apply the jack to near the flowtube support and
insert a steel liner between the bracket and
flowtube support. Never use wooden liner.
In addition, adjust any misalignment when the
flowtube is brought in, as the jack can adjust
vertical misalignments, but not horizontal ones.
