Section 2 MC-III™ EXP Flow Analyzer
• The device has not been assessed as a safety-related device (as referred to by Directive 94/9/EC Annex II,
clause 1.5).
• Installation shall be carried out by suitably trained personnel in accordance with the applicable code of
practice (EN 60079-14 within Europe).
• Repair of this equipment shall be carried out by Cameron or in accordance with the instructions in this
manual.
• If the instrument is likely to come into contact with aggressive substances, the user is responsible for tak-
ing suitable precautions to prevent it from being adversely affected, thus ensuring that the type of protec-
tion is not compromised.
– Aggressive substances may include, but are not limited to, acidic liquids or gases that may attack met-
als, or solvents that may affect polymeric materials.
– Suitable precautions may include, but are not limited to, regular checks as part of routine inspections
or establishing from the material’s data sheet that it is resistant to specic chemicals.
Conditions for Safe Use (ATEX)
• In accordance with EN60079-0, Clause 16.5, all cable and cable glands must be rated for 80ºC.
• Do not remove the cover unless the area is void of combustible gas and vapors.
• Before removing the pipe plug to install a communications adapter, or disassembling the union nut and
blanking plug in a pre-installed communications adapter, make sure the area is nonhazardous. Reinstall
the pipe plug in accordance with the instructions in this manual.
• An ATEX-approved standoff tube shall be used with a Barton 7000 Series turbine pickup coil boss or a
NuFlo turbine pickup coil boss in accordance with certicate SIRA 03ATEX1474U. See the MC-III Parts
List (ATEX), page 100, for part numbers.
• Replace the lithium battery only with the ATEX-approved battery supplied by Cameron (Part No. 9A-
90099000).
• The lithium battery that powers the MC-III EXP is a sealed unit; however, should a lithium battery
develop a leak, toxic fumes could escape upon opening the enclosure. Ensure that the instrument is in a
well-ventilated area before opening the enclosure to avoid breathing fumes trapped inside the enclosure.
Exercise caution in handling and disposing of spent or damaged batteries.
Mounting Options (ATEX)
The ATEX-approved MC-III EXP may be mounted directly to a owmeter, or mounted remotely on a pole
and connected to a owmeter with explosionproof signal cable. The type of meter mount required varies with
the meter in use. See Figures 2.2 through 2.4 for installation dimensions.
• Mount the device to a NuFlo turbine meter. A 3/4-in. to 1-in. standoff tube is required (Figure 2.2, page 21).
• Mount the device to a Barton 7000 Series turbine meter. A 3/4-in. to 3/4-in. stainless steel standoff tube is
required (Figure 2.3, page 21). (The 3/4-in. to 1-in. reducer supplied with the Barton 7000 Series meter is
not required when the standoff tube is used.)
• Mount the device to a at, vertical surface.
• Remote-mount the device to a 2-in. pole using a NuFlo hardware kit (Figure 2.4, page 22). Pole mount-
ing may be preferred where limited space or pipe vibration prohibits direct-mount installation. For best
results, install the device as near as possible to the meter to minimize the length of explosionproof signal
cable that must be used for communications. Stranded, shielded cable is recommended.
