  Maximum wiring distances If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and transmitter depends on cable type. See Table 2. For high-temperature and extreme high-temperature ELITE sensors, note the following: • For sensors with a Model 1700/2700 or a Model 2400S transmitter, the transmitter is considered to be integrally mounted on the sensor, so Table 2 does not apply.

• Page 12: Orienting The Sensor

  Orienting the Sensor Step 2 Orienting the Sensor The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid. Micro Motion recommends orienting ELITE sensors as shown in Table 3. Table 3 Recommended sensor orientations Sensor model CMF010 CMF025, CMF050,…

• Page 13: Mounting The Sensor

  Step 3 Mounting the Sensor Use your common practices to minimize torque and bending load on process connections. Figure 7 illustrates how to mount the sensor. To reduce the risk of condensation or excessive moisture, the conduit opening should not point upward (if possible). The conduit opening of the junction box or core processor can be rotated freely to facilitate wiring.

  Mounting the Sensor Installing extended mount electronics If you ordered a sensor with an extended mount for the electronics, you will need to install the extender. To install the extended mount electronics: 1. There is a metal clamping ring around the base of the feedthrough (Figure 9). Remove this ring and set it aside.

  Wiring Step 4 Wiring Hazardous area installations If you are installing the sensor in a hazardous location, verify that the hazardous classification information printed on the sensor tag matches the environment in which the sensor will be installed. Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure.

• Page 22: Grounding

  Grounding Step 5 Grounding The sensor can be grounded 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.

• Page 23: Purge Fittings

  Purge Fittings If the sensor has purge fittings, they should remain sealed at all times. After a purge plug has been removed, the sensor case should be purged with argon or nitrogen and resealed. Purging the case protects internal components. 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.

  Rupture Disks Table 5 Time required to purge ELITE sensor cases Sensor model CMF010 CMF025 CMF050 CMF100 CMF200 CMF300 CMF400 (1) If purge lines are being used, increase purge time to fill the additional volume. Rupture Disks If the sensor has rupture disks, they are installed in the sensor purge fitting openings. The rupture disks should remain installed at all times.

• Page 25: Return Policy

  Return Policy Return Policy Micro Motion procedures must be followed when returning equipment. These procedures ensure legal compliance with government transportation agencies and help provide a safe working environment for Micro Motion employees. Failure to follow Micro Motion procedures will result in your equipment being refused delivery.
