Planning 1 Planning Topics covered in this chapter: • • • • 1.1 Installation checklist Best practices Temperature limits Recommendations for hygienic and self-draining applications 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. □ Verify that the local ambient and process temperatures are within the limits of the meter.
Planning □ 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. Table 1-3: Preferred sensor orientation Process Preferred orientation Alternate orientations Liquids Gases Slurries □ 1.2 Install the meter so that the flow direction arrow on the sensor case matches the actual forward flow of the process. (Flow direction is also software-selectable.
Planning 1.3 Installation Manual • 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. • Keep the sensor tubes full of process fluid. • For halting flow through the sensor with a single valve, install the valve downstream from the sensor.

Typical center of gravity Note Complete and detailed dimensional drawings, including the location of the center of gravity, can be found through the product drawings link in our online store (www.micromotion.com/onlinestore). 2.2 Mount the sensor Use your common practices to minimize torque and bending load on process connections.
Mounting 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. Figure 2-3: Mounting the sensor Notes • Do not use the sensor to support the piping. • The sensor does not require external supports. The flanges will support the sensor in any orientation. (Some sensor models installed in very small, flexible pipeline have optional installation instructions that allow for external supports.) 2.

Sensor Electronics Mounting bracket Flexible conduit (minimum bend radius 6" [152 mm]) With some large meter sizes, the meter may ship with the electronics attached to the sensor case. The meter cannot be operated in this configuration. Detach the electronics bracket from the sensor case and then proceed to mount the electronics to a wall or instrument pole as described below.

Rotate the sensor alignment rings in the direction that pushes the bolts outward. Tip Rotate both sensor aligment rings until the assembly is centered and tight.
Mounting 6. 2.8 With a wrench, tighten the nuts in an alternating order. Attach extended electronics If you ordered a sensor with extended electronics, you will need to install the extender onto the sensor case. Note Extended core processors are matched at the factory to specific sensors. Keep each core processor together with the sensor with which it was shipped. CAUTION! Keep the extender and feedthrough clean and dry.

Wiring 3 Wiring Topics covered in this chapter: • • • 3.1 Options for wiring Connect 4-wire cable Connect 9-wire cable Options for wiring The wiring procedure you follow depends on which electronics option you have. Table 3-1: Wiring procedures by electronics option Electronics option Wiring procedure Integral transmitter No wiring is required between sensor and transmitter. See the transmitter installation manual for wiring the power and signal cable to the transmitter.
Wiring 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. Note If you are installing unshielded cable in continuous metallic conduit with 360º termination shielding, you only need to prepare the cable – you do not need to perform the shielding procedure.

Slide the shielded heat shrink over the drain wires. Ensure that the wires are completely covered. 2. Apply heat (250 °F or 120 °C) to shrink the tubing. Do not burn the cable. 3.
Wiring • 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.

Wiring Installation Manual 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. 6. Refer to the transmitter installation manual for signal and power wiring instructions.
Grounding 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. 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. • In the U.S.A. and Canada, ISA 12.06.01 Part 1 provides examples with associated applications and requirements.
Supplementary information 5 Supplementary information Topics covered in this chapter: • • 5.1 Purge the sensor case About rupture disks 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. Purging the case protects internal components. The sensor is purged of all oxygen and sealed at the factory.
Supplementary information 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 that the purge gas will displace air from bottom to top.
Supplementary information Table 5-1: Purge time (continued) 7. Sensor model Purge rate, in ft3/hr (l/h) Time, in minutes CMFS100 20 (566) 6 CMFS150 20 (566) 6 At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections with the purge plugs. Note Avoid pressurizing the sensor case. If pressure inside the case elevates above atmospheric pressure during operation, the flowmeter density calibration will be inaccurate. 8. 5.
