(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 sensors 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 connection can be
changed. Read Section 3.5.
In case the fluid being measured flows against the
arrow direction, change the value from “Forward” to
“Reverse” at the parameter “Flow direct”. Read the
user’s manual of the applicable communication type
(for AXW/AXW4A/AXG1A) or the hardware/software
edition (for AXFA11) as listed in Table 1.1.

Lifting
CAUTION
• When carrying the magnetic flowmeter, use the
lifting rings (eye bolts or eye plates).
• To assure safety, keep lifting angle less than 90
degrees as shown in Figure 3.3.1
(3) Transportation and Positioning
Bring in the magnetic flowmeter, place it and use a jack to
adjust its position.
IMPORTANT
Apply the jack to the flanges of the magnetic
flowmeter.
In addition, adjust any misalignment when the
magnetic flowmeter is brought in, as the jack can
adjust vertical position, but not horizontal one.
(4) Applying Gasket and optional Grounding
Rings
Gasket:
Necessary gaskets for piping connection are as
below depending on the choice of grounding rings.
Use sheet gaskets designed to fit for the flange
ratings ad fluid specifications. The GF type-1
gaskets by JIS G 3443-2 should be used for the JIS
F12 flange models in sizes 1100 mm (44 in.) and
above. In this case, the gasket groove is required on
the customer pipe flanges.
The thickness of gasket should be 2 mm (0.08 in.)
to 5 mm (0.2 in.) for sizes up to 1000 mm (40 in.),
and 5 mm (0.2 in.) or more for larger sizes. Use
soft rubber gasket, PTFE-sheathed non-asbestos
gasket, or its equivalent in hardness.
