Determining a Location 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.
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.
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. The CMF010 sensor has an optional mounting configuration (Figure 8) for use with small or soft pipeline.
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. You will use it later to secure the extender to the sensor. 2. The sensor was shipped with a plastic cap over the feedthrough pins. Remove the plastic cap and discard it. 3.

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. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.

For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and g): a. Strip 4 1/2 inches (114 mm) of cable jacket. b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the wires. c.

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. Improper grounding can cause measurement error. Ground the flowmeter to earth, or follow ground network requirements for the facility.
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. For more information, contact Micro Motion Customer Service.
