1.1 Flowmeter components

The transmitter is one component of a Micro Motion flowmeter. The other major component is the sensor.

A third component, called the core processor, provides additional memory and processing functions.

Planning

1.1.1 Installation types

Model 1500 and Model 2500 transmitters can be installed two different ways, only one of which applies to your specific installation.

• 4-wire remote – The transmitter is installed remotely from the sensor. You need to

mount the transmitter separately from the sensor, connect a 4-wire cable between the transmitter and sensor, and connect power and I/O wiring to the transmitter.

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.

If national standards are not in effect, adhere to the following guidelines for grounding:

• Use copper wire, 14 AWG (2.5 mm2) or larger wire size.

• Keep all ground leads as short as possible, less than 1 Ω impedance.

• Connect ground leads directly to earth, or follow plant standards.

1. Ground the sensor according to the instructions in the sensor documentation.

2. Ground the DIN rail.

The rail clip in the base of the transmitter housing grounds the transmitter to the DIN rail.

Mount the remote core processor

This procedure is required only for remote core processor with remote transmitter installations.

For mounting the remote core processor to a wall:

• Use four 5/16-inch diameter (or M8) bolts and nuts that can withstand the process

environment. Micro Motion does not supply bolts or nuts (appropriate bolts and nuts are available as an option).

• Ensure that the surface is flat and rigid, does not vibrate, or move excessively.

For mounting the remote core processor to an instrument pole:

• Use two 5/16-inch U-bolts for 2-inch pipe, and four matching nuts, that can

withstand the process environment. Micro Motion does not supply U-bolts or nuts.

• Ensure the instrument pole extends at least 12 inches (305 mm) from a rigid base,

and is no more than 2 inches (50.8 mm) in diameter.

1. If desired, reorient the core processor housing on the bracket.

a. Loosen each of the four cap screws (4 mm).

b. Rotate the bracket so that the core processor is oriented as desired.

c. Tighten the cap screws, torquing to 30 to 38 in-lbs (3 to 4 N-m).

Mounting and sensor wiring for remote core processor with remote sensor installations

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.

• If ATEX compliance is required, the different cable types have different installation

requirements.

Cable jacket types

All cable types can be ordered with a PVC jacket or Teflon® FEP jacket. Teflon FEP is required for the following installation types:

• All installations that include a T-series sensor.

• All installations with a cable length of 250 ft (75 m) or greater, a nominal flow less

than 20 percent, and ambient temperature changes greater than +68 °F (+20 °C).

Installation Manual 23

Mounting and sensor wiring for remote core processor with remote sensor installations

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. To keep sensor wiring intrinsically safe, keep the sensor wiring separated from power supply wiring and output wiring.

CAUTION!

Keep cable away from devices such as transformers, motors, and power lines, which produce large magnetic fields. Improper installation of cable, cable gland, or conduit could cause inaccurate measurements or flow meter failure.

CAUTION!

Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.

1. Run the cable through the conduit. Do not install 9-wire cable and power cable in

the same conduit.

2. To prevent conduit connectors from seizing in the threads of the conduit openings,

apply a conductive anti-galling compound to the threads, or wrap threads with PTFE tape two to three layers deep.

Wrap the tape in the opposite direction that the male threads will turn when inserted into the female conduit opening.

3. Remove the junction box cover and core processor end-cap.

4. At both the sensor and transmitter, do the following:

a. Connect a male conduit connector and waterproof seal to the conduit opening

for 9-wire.

b. Pass the cable through the conduit opening for the 9-wire cable.

c. Insert the stripped end of each wire into the corresponding terminal at the

sensor and transmitter ends, matching by color. No bare wires should remain exposed.

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. Cable glands from other vendors can be used.

CAUTION!

Install cable glands in the 9-wire conduit opening in the transmitter housing and the sensor junction box. Ensure that the cable drain wires and shields do not make contact with the junction box or the transmitter housing. Improper installation of cable or cable glands could cause inaccurate measurements or flow meter failure.

CAUTION!

1. Identify the components of the cable gland and cable.

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.

5. Pass the cable end through the nipple so the braided shield slides over the tapered

end of the nipple.

6. Slide the compression ring over the braided shield.

7. Screw the compression nut onto the nipple. Tighten the sealing nut and

compression nut by hand to ensure that the compression ring traps the braided shield.

8. Use a 25-mm (1-inch) wrench to tighten the sealing nut and compression nut to

20–25 foot-pounds (27–34 N-m) of torque.

3.8 Ground the flowmeter components

In a remote core processor with remote sensor installation, the transmitter, remote core processor, and sensor are all grounded separately.

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.

If national standards are not in effect, adhere to the following guidelines for grounding:

• Use copper wire, 14 AWG (2.5 mm2) or larger wire size.

• Keep all ground leads as short as possible, less than 1 Ω impedance.

• Connect ground leads directly to earth, or follow plant standards.

1. Ground the sensor according to the instructions in the sensor documentation.

2. Ground the DIN rail.

The rail clip in the base of the transmitter housing grounds the transmitter to the DIN rail.

3. Ground the remote core processor according to applicable local standards, using the remote core processor’s internal ground screw.
