<1> Remove the converter cover. In case of the explosion
proof type cover removal, loosen the Locking Screw
(WAF: 3mm).
<2> For indicator and amplifier unit removal, refer to Section
11.2 “Indicator Removal and Rotation” and Section 11.3
“Amplifier Unit Removal”.
<3> Disconnect the vortex shedder assembly lead-wires from
the converter. In case of the explosion proof type, loosen
the Locking Screw (WAF: 1.5mm).
<4> Remove the bracket mounting bolts and remove the
converter and bracket from the flowmeter body. The
bracket applies to the 1 (25mm) to 4 (100mm) inch
flowmeters.
<5> Remove the hexagon mounting bolts in case of 90-degree
turn.
<6> Turn the converter to the desired orientation. When
reassembling the converter, reverse the above procedure.
<7> After changing the direction, make sure the impedance
between the earth terminal and the metal part of body,
vortex shedder assembly or bracket is 100RUOHVV
