3.3.6 Nomial Diameter 15 mm (0.5 in.) to
125 mm (5.0 in.), Sanitary Type
The sanitary type can be mounted to the piping using a
clamp, a union, or a welded joint.
NOTE
Thissectiondescribestheremoteowtubeasan
example. The same procedure also applies to the
integralowmeter.
Sanitary adapters are engraved with character as
identication.

(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. Refer to the applicable user’s manuals
which can be downloaded from our website.
Incasetheuidbeingmeasuredowsagainstthe
arrowdirection,changethevaluefrom“Forward”to
“Reverse”attheparameter[J20:FlowDirection]
(refer to Chapter 8).
(2) Mounting Procedure
(a) Clamp type
(process connection codes: HAB, HDB, and HKB)
1) Welding ferrule
Weld a ferrule to the piping.
IMPORTANT
When welding the ferrule, pay attention to the edge
preparation, level differences between the ferrule and
the piping, and the welding current to avoid deforming
thepipingorcausingstagnationportionoftheuid.
2) Installing gasket
Installagasketforclamptotinthegrooveonthe
ferrule.
3) Positioningowmeter
Positiontheowmeterbetweenthetwoferrules.
4) Tightening clamp
Install a clamp to cover the tapered parts of the
owmeter-sideadapterandtheferrule,and
tighten the clamp screw.
5) Conrmationofadaptermountingscrew
Afterinstallationofthemagneticowmeter,be
sure to retighten the adapter mounting screw
according to Table 3.3.18 or Table 3.3.19.
Besuretoconrmthatleakagefromadapter
connectionpointdoesnotoccurbyllingthepipe
oftheowtubewithuid.
NOTE
The ferrule, clamp, and gasket are not provided with
theowmeter,andmustbeprovidedbytheuser.

(b) Union type
(processconnectioncodes:JDB,JKB,andJSB)
1) Welding sleeve
Pass the piping through a nut and then weld a
sleeve to the piping.
IMPORTANT
• Be sure to weld the sleeve after passing the piping
through the nut.
• When welding the sleeve, pay attention to the
edge preparation, level differences between the
sleeve and the piping, and the welding current to
avoid deforming the piping or causing stagnation
ofsomeoftheuid.
2) Installing gasket
Installagasketforuniontotinthegrooveonthe
sleeve.
3) Positioningowmeter
Move the nut closer to the piping temporarily and
positiontheowmeterbetweenthetwosleeves.
4) Tightening nut
Install the nut to cover the tapered parts of the
owmeter-sideadapterandthesleeve,and
tighten it using a wrench.
