•Mountingorientation
IMPORTANT
Installthemagneticowmetersothatthe
electrodes position is not perpendicular to the
ground. Otherwise it may cause the measuring
errors because air bubbles at upper side or slurry
at downside covers the electrode.
Mountthetransmitteroftheowmeterabovethe
piping to prevent water from entering them.

IMPORTANT
• Forauidcontaininghighconcentration
slurries or hard solids (such as earth and
sand,metalpowder,andber),contactof
the solids on the electrode surface will make
theoutputuctuate.Therefore,two-wire
magneticowmetersarenotsuitablefor
measuringsuchuids.Itisrecommendedto
usetheAXFfour-wiremagneticowmeter.
• Inthevicinityofanelectrolysisbath,strong
straycurrentmayowintheuid.Itis
recommendedtousetheAXFfour-wire
magneticowmeterinsuchanapplication.
3.2 Handling Precautions
WARNING
Themagneticowmeterisaheavyinstrument.
Be careful that no damage is caused to
personnel through accidentally dropping it, or
by exerting excessive force on the magnetic
owmeter.Whenmovingthemagnetic
owmeter,alwaysuseatrolleyandhaveatleast
two people carry it.
3.2.1 General Precautions
(1) Precaution during Transportation
Themagneticowmeterispackedtightly.When
it is unpacked, pay attention to prevent damaging
theowmeter.Topreventaccidentswhileitisbeing
transported to the installing location, transport it to
the site in its original packing.
CAUTION
Inordertoliftamagneticowmeterthatistted
with eyebolts, proceed as in Figure 3.2.1. Never
liftitusingabarpassedthroughtheowtubeas
this damages the liner severely.
(2) Avoid Shocks from Impact
CAUTION
Careshouldbetakennottodroptheowmeter
or expose it to excessive shock. In particular, be
carefulnottosubjecttheangesurfacetoshock.
This may lead to liner damage which will result in
inaccurate readings.
(3) Flange Protection Covers
IMPORTANT
Keep the protective covering (i.e. the corrugated
cardboard or other cushioning material) in place
overtheangeexceptwhenmountingthe
owmetertothepipe.
