  • Page 3: Installation Checklist

    Planning Installation Checklist q Make sure that the hazardous area specified on the sensor approval tag is suitable for the environment in which the sensor is installed. q Verify that the local ambient and process temperatures are within the limits of the sensor. See Environmental Limits. q If your sensor has an integral transmitter, no wiring is required between the sensor and transmitter.

    Planning Figure 1 Center of Gravity for Large Meters Approximate center of gravity Environmental Limits The ambient and process temperature limits of the sensor are shown in the following figures. • For all ELITE sensor models except high-temperature and extreme-high-temperature models, see Figure 2. •...
  • Page 6 • For the purposes of selecting electronics options, this graph should be used only as a general guide. If your process conditions are close to the gray areas, it may be inappropriate to use electronics options other than a junction box. Consult with your Micro Motion representative.

  • Page 7 Planning Figure 3 Environmental Limits for High-Temperature Sensors Notes • When ambient temperature is below –40 °F (–40 °C), a core processor or Model 2400S transmitter must be heated to bring its local ambient temperature to between –40 °F (–40 °C) and +140 °F (+60 °C). Long-term storage of electronics at ambient temperatures below –40 °F (–40 °C) is not recommended.

  • Page 8: Mounting Elite Sensor

    Do not lift the sensor by the electronics or purge connections. Lifting the sensor by the electronics or purge connections can damage the device. Micro Motion ELITE Coriolis Flow and Density Sensors...

  • Page 9: Mounting A Cmf010 Sensor To A Wall Or Pole

    Mounting Mounting 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, this procedure can be skipped. 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.

With your fingers, tighten the flange nuts. Rotate the sensor alignment rings in the direction that pushes the bolts outward. See Figure 8. Rotate both rings until the assembly is centered and tight.

  • Page 12: Mounting Electronics Of High-Temperature Sensors

    The electronics of high-temperature ELITE sensors are attached to the end of a 32² (812 mm) pre-installed flexible conduit. The electronics must be separately mounted on a wall or instrument pole. The components of high-temperature sensor electronics are shown in Figure 9.

    Mounting Figure 11 Pole-Mount Components Instrument pole Electronics (Model 2400S transmitter shown) Flexible conduit Attaching Extended Electronics If you ordered a sensor with extended electronics, you will need to install the extender onto the sensor case. Note Extended core processors are matched at the factory to specific sensors. Keep each core processor together with the sensor with which it was shipped.
  • Page 16 Fit the extender onto the feedthrough by carefully aligning the notches on the bottom of the extender with the notches on the feedthrough. Close the clamping ring and tighten the clamping screw to 13–18 in-lbs. (1,5–2 N-m). Micro Motion ELITE Coriolis Flow and Density Sensors...

  • Page 21 Grounding The sensor must be grounded. You can ground the sensor via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw, which is located on the transmitter, core processor, or junction box.

    Make sure that there is a tight seal between the inlet connection and sensor case, so that air cannot be drawn by suction into the case or purge line during the purging process. Micro Motion ELITE Coriolis Flow and Density Sensors...

  • Page 23: About Rupture Disks

    Supplementary Information Run purge gas through the sensor. The purge time is the amount of time required for full exchange of atmosphere to inert gas. The larger the line size, the greater amount of time is required to purge the case. See Table 4. If purge lines are being used, increase the purge time to fill the additional volume of the purge line.
