INSTRUCTION MANUAL 10DX3111A&G Sizes 14 - 24 Inches
2.2 Meter Handling
The exposed liner material on the faces of both meter flanges are susceptible to damage if mishan-
dled. Do not walk the meter on its ends. Always use the protective end covers when the meter is
transported. These protective end covers can be removed for inspection and must be removed before
mounting the meter in the pipeline.
Never allow support for the Magnetic Flowmeter to bear
upon the inner surface of the meter pipe section inasmuch
as the liner may become damaged. Do not lift the meter by
As shown in Figure 2-9, ABB Automation has developed a liner protector/grounding ring for the 14
inch TEFLON
lined meters. These protector plates are turned on both the inside and outside edges.
Turning the inside edge protects the leading edge of the meter liner from process abrasion. Turning
the outside edge reduces the probability that a prying tool will be jammed against the liner during
removal of the meter from the line.
When liner protector plates/grounding rings are attached to the
meter flanges, do not remove them; removal will cause the
TEFLON
A TEFLON
liner of the flowmeter must be protected at all times for two reasons.
• the TEFLON
• if the pressure on the flanges is relieved the TEFLON will tend to curl away
from the flange
Also included in the shipping crate is an installation kit, which consists of the following items:
a) Two gaskets
b) Required seal fittings (depending on model).
The proper use of these items as described in the following text, and the proper employment of them
during installation is necessary to maintain a valid instrument warranty. In some cases, the installa-
tion of the meter and the corresponding gaskets may be made easier by using talcum powder (or a
similar dry lubricant) on the gaskets to allow the gaskets to slide more easily over the lined flange
face during the installation procedure.
