Although a vertical installation of your meter is

best, a horizontal or sloping installation can be

very successful if the meter electrodes are ori-

ented in a horizontal plane. If either electrode is

positioned at the top, entrapped air may act as an

insulator, resulting in an unreliable measurement.

This tag highlights the installation techniques necessary for depend-

able service from your ABB Magnetic Flowmeter. By observing and

performing these operations, your meter warranty remains valid and

satisfactory performance is assured. Coverage of all recommenda-

tions given in this instruction is provided in detail within the Instruction

Manual which accompanies your meter.

METER GASKETS

Two gaskets are provided in the Installation Kit, as selected for the

particular application.

CONDUIT CONNECTIONS

Conduit seal fittings must be properly installed at the meter primary to

prevent condensate, that may be present in the conduit system, from

entering the customer connection box and degrading meter perform-

ance.

Conduit seals are also required to prevent the process fluid from en-

tering the electrical conduit system. This safety feature considers the

remote possibility of a primary seal failure within the flowmeter, in

which case, this secondary seal will prevent the process from enter-

ing the electrical conduit system in accordance with the National

Electrical Code (NEC) ANSI/NFPA 70, Article 501-5 (f) (3). A cable

seal and mating fittings are supplied with the meter for cables that in-

terconnect with a remotely mounted signal converter. When an inte-

grally mounted signal converter is supplied, cable seals and fittings

are provided only when the accidental submergence option has been

specified.

Proper assembly of the cable

seal and fittings is illustrated

in the adjacent diagram. If the

seal provided contains plugs

in the thru-holes, remove only

those plugs required to ac-

commodate necessary wiring.

The proper use of conduit and

seals provides physical pro-

tection for all external wiring,

makes the meter weatherproof

and provides added assur-

ance

against

stray pick up on signal trans-

mission leads.
