IMPORTANT
Please use appropriate bolts and nuts according
to process connection. In case stud type of
through bolts are used, be sure outside diameter
of a shank is smaller than a thread ridge’s one.
Please use compressed non-asbestos fiber
gasket, PTFE gasket or the gasket which has
equal elasticity. In case of optional code/FRG,
please use rubber gasket or others which has
equal elasticity. Be sure the inner diameter of
the gasket does not protrude to inner piping.
(Refer to Table 4.3.8)
(1) Mounting Direction
Please mount the Magnetic Flowmeter matching the
flow direction of the fluid to be measured with the
direction of the arrow mark on the flowmeter.
IMPORTANT
If it is impossible to match the direction, please
never remodel by changing direction of the
converter. In case the measuring fluid flows
against the arrow direction, please refer to the
section 6.3.6 or 7.2.8 Reversing Flow Direction.
(2) Mounting Centering Devices
To keep concentricity of the Flowmeter with pipes,
please mount centering devices on the Mini-Flanges of
the Flowmeter.
Please give attention to the nominal diameter and
flange ratings of the centering devices.
(3) Positioning Flowmeter
Please pass two through-bolts to adjacent holes of both
flanges and mount the Flowmeter, and pass other
through-bolts to other holes. (Refer to Figure 4.3.2/
4.3.3) In case stud type of through-bolts are used,
position them coming in contact centering devices with
thread of bolts.
(4) Tightening Nuts
Please tighten the bolts according to Torque Values in
Table 4.3.3. In case of PVC piping, please select
optional code /FRG, use rubber gasket and tighten with
the torque value in Table 4.3.4.
