Determining a Location Hazardous area installations Make sure the hazardous area specified on the sensor approval tag is suitable for the environment in which the sensor is installed. (See Figures 1–5.) For installation in an area that requires intrinsic safety, refer to the appropriate Micro Motion approval documentation, shipped with the sensor or available from the Micro Motion web site at www.micromotion.com.
Determining a Location Hazardous area approvals may impose additional limits on ambient and process temperature. For the ATEX “T” rating, refer to the ATEX documentation shipped with the sensor or available on the Micro Motion web site at www.micromotion.com. UL, CSA, and IECEx ambient temperature limits are listed in Table 1.
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 Figure 7 illustrates how to mount the sensor. The CMF010 sensor has an optional mounting configuration (Figure 8) for use with small or soft pipeline. 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 Mounting the electronics of high-temperature sensors Model CMF100A, CMF200A, CMF300A, and CMF400A sensors come with a 32″ (812 mm) pre-installed flexible conduit. This conduit is required for agency approval. A factory-supplied Model 2400S transmitter, Model 1700/2700 transmitter, core processor, or junction box is connected to the end of the flexible conduit. Mount the electronics to a wall or instrument pole using the supplied bracket (Figure 9).

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. WARNING Failure to comply with the requirements for intrinsic safety in a hazardous area could result in an explosion.
Wiring Core processor to a 4-wire remote transmitter Follow the steps below to connect the 4-wire cable between the core processor and the transmitter. 1. Use one of the following methods to shield the wiring from the core processor to the transmitter: • If you are installing unshielded wiring in continuous metallic conduit that provides 360° termination shielding for the enclosed wiring, go to page 17 (step 6 of the wiring procedure).
Wiring Figure 13 Wrapping the shield drain wires e. Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires. f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing. Figure 14 Applying the heat shrink g. Position gland clamping insert so the interior end is flush with the heat shrink. h. Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring.
Wiring Figure 16 Gland body and core processor housing 5. Insert the wires through the gland body and assemble the gland by tightening the gland nut. If desired, leave sufficient wire length inside the core processor housing to allow the housing to rotate without damaging the wires. 6. Identify the wires in the 4-wire cable.
Grounding Junction box to a 9-wire remote transmitter or remote core processor Follow the steps below to connect the 9-wire cable between the sensor and the transmitter or core processor. 1. Prepare and install the cable according to the instructions in Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide. 2. Insert the stripped ends of the individual wires into the terminal blocks. No bare wires should remain exposed. 3. Match the wires color for color.
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.
Purge Fittings 4. Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open. • Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case. • If the purge gas is heavier than air (such as argon), locate the inlet lower than the outlet, so the purge gas will displace air from bottom to top.
Rupture Disks 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. If you remove a rupture disk from the sensor case, it will be necessary to re-purge the case (see Case purging procedure on page 19). Rupture disks are meant to vent process fluid from the sensor case in the event of a flow tube rupture. Some users connect a pipeline to the rupture disk to help contain escaping process fluid.
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. Information on return procedures and forms is available on our web support system at www.micromotion.
