Determining a Location Step 1 Determining a Location Choose a location for the sensor based on the requirements described in this section. The following general guidelines can help you select an appropriate location for the sensor. Full flow tubes For optimal performance, the sensor tubes should remain full of process fluid. 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).

Determining a Location Maximum wiring distances If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and transmitter depends on cable type. See Table 2. For high-temperature and extreme high-temperature F-Series sensors, note the following: • For sensors with a Model 1700/2700 transmitter, the transmitter is considered to be integrally mounted on the sensor, so Table 2 does not apply.
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 F-Series sensors as shown in Figure 8.
Mounting the Sensor Step 3 Mounting the Sensor Use your common practices to minimize torque and bending load on process connections. Figure 9 illustrates how to mount the sensor. 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 and extreme high-temperature sensors High-temperature and extreme high-temperature F-Series sensors come with a 32″ (812 mm) pre-installed flexible conduit. This conduit is required for agency approval. A factory-supplied 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 10).
Wiring Step 4 Wiring Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings. Installation options The sensor has one of the following electronics configurations: • An integral Model 1700/2700 or IFT9701 transmitter. No wiring is required between the sensor and the transmitter. Skip to Grounding on page 19.

For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and g): a. Strip 4 1/2 inches (114 mm) of cable jacket. b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the wires. c.

Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring. Figure 14 Folding the cloth shield i. Install the gland body into the core processor housing conduit opening. Figure 15 Gland body and core processor housing 5. Insert the wires through the gland body and assemble the gland by tightening the gland nut.

Grounding Step 5 Grounding The sensor can be grounded via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw, which is located on the core processor housing or junction box. Improper grounding can cause measurement error. Ground the flowmeter to earth, or follow ground network requirements for the facility.
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 Table 4 Time required to purge F-Series sensor cases Sensor model Purge rate ft3/hr (l/hr) Time(1) minutes F025 20 (566) 4 1/2 F050 20 (566) 4 1/2 F100 20 (566) 6 F200 20 (566) 15 F300 20 (566) 25 (1) If purge lines are being used, increase purge time to fill the additional volume. 8. Make sure the purge fitting seals are tight so air cannot be drawn by suction into the sensor case.
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.
