1 Planning Topics covered in this chapter: • Installation checklist • Best practices • Temperature limits • Recommendations for hygienic and self-draining applications 1.1 Installation checklist □ Make sure that the hazardous area specified on the approval tag is suitable for the environment in which the meter will be installed.
□ For optimal performance, install the sensor in the preferred orientation. The sensor will work in any orientation as long as the flow tubes remain full of process fluid.
• There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe upstream or downstream are unnecessary. • If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor. Gases may flow upward or downward.

3 Wiring Topics covered in this chapter: • Options for wiring • Connect 4-wire cable • Connect 9-wire cable 3.1 Options for wiring The wiring procedure you follow depends on which electronics option you have.
3.2 Connect 4-wire cable 3.2.1 Prepare the 4-wire cable Important For user-supplied cable glands, the gland must be capable of terminating the drain wires.
4-wire cable preparation Figure 3-1: Cable layout Run conduit to sensor Metal conduit Wrap the drain wires twice around the shield and cut off the excess drain wires. Micro Motion cable gland Pass the wires through the gland. Terminate the drain wires inside the gland.
4-wire cable shielding Figure 3-2: Assemble the Gland 1. Fold the shield or braid back over the clamping insert and 1/8 inch (3 mm) past the O-ring. 2. Install the gland body into the conduit opening on the core processor housing. 3. Insert the wires through gland body and tighten the gland nut onto the gland body.
• Twisted pair construction. • Applicable hazardous area requirements, if the core processor is installed in a hazardous area. • Wire gauge appropriate for the cable length between the core processor and the transmitter. Wire gauge Table 3-2: Wire gauge Maximum cable length VDC 22 AWG (0.
Core processor terminals Figure 3-3: Connect the wires to the transmitter terminals (see the transmitter manual) Reinstall and tighten the core processor cover Core processor type From Step 1 or 2 Con.
3. Match the wires color for color. For wiring at the transmitter or remote core processor, refer to the transmitter documentation. 4. Tighten the screws to hold the wires in place. 5. Ensure integrity of gaskets, then tightly close and seal the junction box cover and all housing covers on the transmitter or core processor.
4 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.
5 Supplementary information Topics covered in this chapter: • Purge the sensor case • About rupture disks 5.1 Purge the sensor case 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.
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.
Purge time (continued) Table 5-1: Sensor model Purge rate, in ft 3 /hr (l/h) Time, in minutes CMFS100 20 (566) 6 CMFS150 20 (566) 6 7. At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections with the purge plugs.
