10DX3111 INSTRUCTION MANUAL
4.0 MAINTENANCE
4.1 General
Although the Series 10DX3111 Magnetic Flowmeter is of inherently rugged design, normal care
used in the handling, installation and maintenance of the meter will contribute substantially toward
trouble-free operation. As the Magnetic Flowmeter has no moving parts, the necessity for specify-
ing or requiring replacement parts is limited.
Electrodes can be replaced in NEOPRENE and Polyurethane-lined meters without removal of the
meter from the pipeline.
Contact ABB Instrumentation for part numbers of field replaceable parts.
4.2 Routine Maintenance
No routine maintenance procedures should be required for the normal application.
For those applications where the fluid being metered consists of sludge, unusually greasy mixants,
or other insulating mixants which normally tend to coat pipe walls, it is advisable to visually inspect
the inner meter walls periodically. This procedure is facilitated by use of a plugged pipe tee in a by-
pass piping configuration, as shown in Figure 2-2. The pipe tee also provides easy access for
cleaning polyurethane-lined meters with a wire brush or cleaning NEOPRENE-lined meters with a
ball bristle brush.
