Series 10DX3000 Magnetic Flowmeter Instruction Manual
Construction of the meter is dependent on
the type of insulating interior liner used. A
®
TEFLON (PTFE) liner is inserted into the
spool and turned-out against the flange
faces. All other liner materials are bonded to
the interior and face of the pipe spool. For all
liner materials, two cylindrical electrodes are
mounted diametrically opposed within the
central portion of the meter body and are
completely insulated from the metal pipe.
The end surfaces of the electrodes are virtu-
ally flush with the inner surface of the insulat-
ing liner and come into contact with the liquid
to be metered.
The primary housing for the continuous sub-
mergence & explosion-proof design is differ-
ent from the other configurations in that it is
sealed with a round screw-on access cover.
The interior of this housing is filled with a
gelatin-like silicone rubber compound which
helps give the meter its waterproof rating.
The construction of this meter is shown in
FIGURE 1-1.
The NEMA 4X rating applies to the meter body and electronics enclosure only. The following
accessories (if supplied) may not meet NEMA 4X unless specifically ordered as NEMA 4X:
• meter flanges
• meter installation hardware: studs, nuts, bolts
• enclosure mounting hardware for pipe or wall mounting
• conduit hardware
This product is painted with a high performance epoxy paint. The corrosion
protection provided by this finish is only effective if the finish is unbroken. It is the
users' responsibility to "touch-up" any damage that may occur to the finish during
shipping or installation of the product. Special attention must be given to meter
flange bolting, pipe mounting of electronics, conduit entries and covers that are re-
moved to facilitate installation or repair. For continuing corrosion protection
throughout the product life, it is the users' responsibility to maintain the product fin-
ish. Incidental scratches and finish damage must be repaired and promptly re-
