    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 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.

    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 12.2.2.3 and 12.2.2.4.
  • Page 33: Chapter 5 Supplementary Information

    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.
  • Page 34 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. •...

  • Page 36: Pressure Relief

    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.
  • Page 37 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.
