IMPORTANT
Useboltsandnutsincompliancewiththeange
ratings. Be sure to choose a gasket with inner
and outer diameters that does not protrude
inside the piping (Read Subsection 3.3.4). If the
inner diameter of the gasket is too large, or outer
diameterofthegasketistoosmall,uidleakage
may result.
(1) Mounting Direction
Mounttheowmetersothattheowdirectionofthe
uidtobemeasuredisinlinewiththedirectionof
thearrowmarkontheowmeter.
IMPORTANT
If it is impossible to match the direction of
the arrow mark, the direction of the electrical
connection can be changed. Read Section 11.1
to do this properly.
Incasetheuidbeingmeasuredowsagainst
the arrow direction, read the parameter J20:
Flow Direction in this user’s manual.
(2) Tightening Nuts
Tighten the bolts according to the torque values
for the metal piping in Table 3.3.9. For PVC piping,
select an optional code of GA, GC, or GD, use
rubber gaskets and tighten the nuts to the torque
values for the PVC piping in Table 3.3.10.
Forpermeableuids(suchasnitricacid,
hydrouoricacid,orsodiumhydrateathigh
temperatures), tighten the nuts according to the
torque values in Table 3.3.11.
CAUTION
ForaowmeterwithuorocarbonPFAlining,
it is possible that the nuts may loosen as time
passes, so tighten them regularly. Be sure to
tighten the nuts according to the prescribed
torque values. Tighten them diagonally with
the same torque values, step by step up to the
prescribed torque value.
