• Temperature limits may be further restricted by hazardous area approvals. Refer to the hazardous area approvals documentation shipped with the sensor or available at www.emerson.com. • The extended-mount electronics option allows the sensor case to be insulated without covering the transmitter, core processor, or junction box, but does not affect temperature ratings.

Mounting Mount the sensor Use your common practices to minimize torque and bending load on process connections. To reduce the risk of condensation problems, do not orient transmitters or sensor junction boxes with their conduit openings pointing upward. CAUTION! Do not lift the sensor by the electronics or purge connections. Lifting the sensor by the electronics or purge connections can damage the device.
Mounting Rotate junction box or 800 core processor (optional) An integrally mounted junction box or 800 core processor can be rotated to one of eight possible positions in 45 degree increments. Figure 2-4: Parts for rotating the junction box or 800 core processor on the sensor Housing Clamping ring Clamping ring screw...
Mounting Mount electronics of high-temperature sensors The electronics of high-temperature sensors are attached to the end of a 32" (812 mm) pre-installed flexible conduit. The electronics must be separately mounted on a wall or instrument pole. Figure 2-5: Components of a high-temperature sensor Sensor Electronics Mounting bracket...

Mounting Mount a CMF010 sensor to a wall or pole The CMF010 sensor has an optional mounting configuration for use with small or flexible pipeline. If the pipeline adequately supports the sensor, you can skip this procedure. Locate the optional mounting holes. For sensors with a junction box, the junction box must be rotated to the side to expose the mounting holes.
Mounting Mount a CMFS007, CMFS010 or CMFS015 sensor in a bracket The CMFS007, CMFS010 and CMFS015 sensors have an optional mounting bracket for use with small or flexible pipeline. If the pipeline adequately supports the sensor, this procedure can be skipped. Secure the mounting bracket to a wall or other flat surface with four user-supplied 5/16"...
Mounting Mount a CMFS025, CMFS040 or CMFS050 sensor in a wall mount bracket The CMFS025, CMFS040, and CMFS050 sensors have an optional wall mounting bracket. Assemble the bracket. Figure 2-11: Assembled wall mounting bracket for CMFS025, CMFS040, and CMFS050 Attach the bracket to the wall using fasteners appropriate for the mounting surface. Place the sensor into the bracket.
Mounting Secure wafer-style process connections A wafer-style connection lets you clamp the sensor into the pipeline. A wafer installation kit is shipped with a wafer-style sensor. Make sure that the bolts provided are rated for your process connection. Slip the sensor alignment rings over each end of the sensor wafer, then insert the sensor between the process connections in the pipeline.

Transmitter power and I/O wiring CAUTION! Fully close and tighten all housing covers and conduit openings. Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Inspect and grease all gaskets and O-rings. Connect 4-wire cable 3.2.1 4-wire cable types and usage Micro Motion offers two types of 4-wire cable: shielded and armored.

Grounding Grounding The meter must be grounded according to the standards that are applicable at the site. The customer is responsible for knowing and complying with all applicable standards. Prerequisites Micro Motion suggests the following guides for grounding practices: • In Europe, IEC 79-14 is applicable to most installations, in particular Sections 220.127.116.11 and 18.104.22.168.
Supplementary information Supplementary information Topics covered in this chapter: • Purge the sensor case • Pressure relief Purge the sensor case If the sensor has purge fittings, they should remain sealed at all times. The sensor is purged of all oxygen and sealed at the factory. If the purge plugs are never removed, it is not necessary to purge or re-seal the sensor.
Supplementary information Prepare the purge plugs for reinstallation by wrapping them with 2–3 turns of Teflon tape. Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open. •...
Supplementary information Table 5-1: Purge time (continued) Sensor model Purge rate, in ft /hr (l/h) Time, in minutes CMFS050 20 (566) 4 1/2 CMFS075 20 (566) CMFS100 20 (566) CMFS150 20 (566) At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections with the purge plugs.
Supplementary information Pressure relief ELITE sensors are available with a rupture disk installed on the case. Rupture disks are meant to vent process fluid from the sensor case in the unlikely event of a flow tube breach. Some users connect a pipeline to the rupture disk to help contain escaping process fluid.
Supplementary information WARNING! Removing the Purge Fitting, Blind Plug, or Rupture Disks compromises the Ex-i Safety Certification, the Ex-tc Safety Certification, and the IP-rating of the Coriolis meter. Any modification to the Purge Fitting, Blind Plug, or Rupture Disks must maintain a minimum of IP66/IP67 Ratings.
