The Primary housing for the continuous
submergence and explosion-proof design
is different from the other configurations in
that it is sealed with a round screw-on ac-
cess 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 protec-
tion provided by this finish is only effective if the finish is unbroken. It is the users'
responsibility to "touch-up" any damage that has occurred to the finish during ship-
ping or installation of the product. Special attention must be given to: meter flange
bolting, pipe mounting of electronics, conduit entries and covers that are removed
to facilitate installation or repair. For continued corrosion protection throughout the
product life, it is the users' responsibility to maintain the product finish. Incidental
scratches and other finish damage must be repaired and promptly re-painted with
approved touch-up paint. Provide the model number and size of your product to the
nearest factory representative to obtain the correct touch-up paint.
