1 Planning Topics covered in this chapter: • Flowmeter components • Outputs option identification • Environmental limits • Hazardous area classifications • Power requirements 1.1 Flowmeter components The transmitter is one component of a Micro Motion flowmeter.
4-wire remote installation Figure 1-1: Sensor Core processor Transmitter 4-wire cable • Remote core processor with remote sensor – A remote core process with remote sensor installation separates all three components – transmitter, core processor, and sensor – all of which are installed separately.
Remote core processor with remote sensor installation Figure 1-2: Core processor Transmitter 4-wire cable 9-wire cable Sensor Junction box 1.1.2 Maximum cable lengths The maximum cable length between flowmeter components that are separately installed is determined by cable type.
The transmitter's model number is on a tag on the side of the transmitter. You can use the model number to determine the transmitter's output option. The first four characters are the transmitter type. The fifth character is the installation type.
• Verify that the transmitter has the appropriate hazardous area approval. Each transmitter has a hazardous area approval tag attached to the transmitter housing. • Ensure that any cable used between the transmitter and the sensor meets the hazardous area requirements.
2 Mounting and sensor wiring for 4- wire remote installations Topics covered in this chapter: • Mounting the transmitter to a DIN rail • Prepare the 4-wire cable • Wire the transmitter to the sensor • Ground the flowmeter components 2.1 Mounting the transmitter to a DIN rail The transmitter is designed to be mounted on a 35 mm DIN rail.

4-wire cable shielding Figure 2-4: 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 2-1: Wire gauge Maximum cable length VDC 22 AWG (0.
CAUTION! Improper grounding could cause inaccurate measurements or flow meter failure. Failure to comply with requirements for intrinsic safety in a hazardous area could result in an explosion. Note For hazardous area installations in Europe, refer to standard EN 60079-14 or national standards.

Terminal connections for 4-wire cable Figure 3-7: RS-485B RS-485A VDC– VDC+ 3.5 Prepare the 9-wire cable Micro Motion supplies three types of 9-wire cable: jacketed, shielded, and armored. The type of cable you are using determines how you will prepare the cable.
Preparing jacketed cable Figure 3-8: 1. Trim 4 inches (100 mm) of cable jacket. 2. Remove the clear wrap and filler material. 3. Remove the foil that is around the insulated wires and separate them. 4. Identify the drain wires in the cable and bring them together.
Preparing shielded or armored cable Figure 3-9: 1. Without cutting the shield, strip 9 inches (225 mm) of cable jacket. 2. Strip 8 ½ inches (215 mm) of braided shield, so ½ inch (10 mm) of shield remains exposed. 3. Remove the foil shield that is between the braided shield and inner jacket.
Cable types Micro Motion supplies three types of 9-wire cable: jacketed, shielded, and armored. Note the following differences between the cable types: • Armored cable provides mechanical protection for the cable wires. • Jacketed cable has a smaller bend radius than shielded or armored cable.
Bend radii of armored cable Table 3-5: Jacket material Outside diameter Minimum bend radii Static (no load) condition Under dynamic load PVC 0.525 inches (14 mm) 4–1/4 inches (108 mm) 8–1/2 inches (216 mm) Teflon FEP 0.

3.6 Wire the remote core processor to the sensor using jacketed cable For ATEX installations, the jacketed cable must be installed inside a user-supplied sealed metallic conduit that provides 360° termination shielding for the enclosed cable. CAUTION! Sensor wiring is intrinsically safe.

3.7 Wire the remote core processor to the sensor using shielded or armored cable For ATEX installations, shielded or armored cable must be installed with cable glands, at both the sensor and remote core processor ends. Cable glands that meet ATEX requirements can be purchased from Micro Motion.
3. Screw the nipple into the conduit opening for the 9-wire cable. Tighten it to one turn past hand-tight. 4. Slide the compression ring, compression nut, and sealing nut onto the cable. Make sure the compression ring is oriented so the taper will mate properly with the tapered end of the nipple.
