4.3 Mounting
4.3.1 Nominal Diameter 15mm (0.5") to 40 mm (1.5")
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
4.3.6)
A: Mounting Direction
Please mount the Magnetic Flowmeter matching the flow direction to be measured with
the direction of the arrow mark on the flowmeter.
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 6.4.6 Reversing Flow Direction.
B: Mounting Centering Devices
To keep concentricity of the Flow Tube with pipes, please mount centering devices on
the Mini-Flanges of the Flow Tube.
Please give attention to the nominal diameter and flange ratings of the centering devices.
C: Positioning Flow Tube
Please pass two through-bolts to lower adjacent holes of both flanges and mount the
Flow Tube, and pass other through-bolts to other holes. (Refer to Figure 4.3.1 / 4.3.2)
In case stud type of through-bolts are used, position them coming in contact centering
devices with thread of bolts.
D: Tightening Nuts
Please tighten the bolts according to Torque Values in Table 4.3.1. In case of PVC
piping, please select optional code /FRG, use rubber gasket and tighten with the torque
value in Table 4.3.2.
Please be sure to tighten the bolts following prescribed torque values.
Please tighten the flange bolts diagonally with the same torque values, step
by step up to the prescribed torque value.
