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. • You should be able to stop flow through the sensor to facilitate the zeroing procedure. • For optimal performance, the sensor should remain full of process fluid.
Determining a Location Environmental limits The maximum ambient temperature for the sensor depends on the electronics option: • For F-Series sensors with a junction box or an extended core processor, the maximum ambient temperature is 140 °F (60 °C). • For all Model F300A sensors, the maximum ambient temperature is 140 °F (60 °C). • For F-Series sensors with an integral core processor or Model 1700/2700 transmitter, the maximum ambient temperature is described by the graph in Figure 8.
Determining a Location Maximum wiring distances The maximum distance between the sensor and transmitter depends on cable type. See Table 2.
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 9.
Mounting the Sensor Step 3 Mounting the Sensor Use your common practices to minimize torque and bending load on process connections. Figure 10 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 Figure 11 Mounting the Model F300A electronics Mounting bracket (wall mount) Use 4 × 5/16″ (8 mm) bolts to secure the bracket to a wall Mounting bracket (instrument pole) Use 2 × 5/16″ (8 mm) U-bolts to secure the bracket to an instrument pole Slide the electronics into the bracket groove. Secure the electronics to the bracket with the 4 #10 screws.
Wiring Step 4 Wiring Hazardous area installations If you are installing the sensor in a hazardous location, verify that the hazardous classification information printed on the sensor tag matches the environment in which the sensor will be installed. WARNING Failure to comply with the requirements for intrinsic safety in a hazardous area could result in an explosion.
Wiring Core processor to a 4-wire remote transmitter Follow the steps below to connect the 4-wire cable between the core processor and the transmitter. 1. Use one of the following methods to shield the wiring from the core processor to the transmitter: • If you are installing unshielded wiring in continuous metallic conduit that provides 360° termination shielding for the enclosed wiring, go to page 20 (step 6 of the wiring procedure).
Wiring Figure 13 Wrapping the shield drain wires e. Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires. f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing. Figure 14 Applying the heat shrink g. Position gland clamping insert so the interior end is flush with the heat shrink. h. Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring.
Wiring Figure 16 Gland body and core processor housing 5. Insert the wires through the gland body and assemble the gland by tightening the gland nut. If desired, leave sufficient wire length inside the core processor housing to allow the housing to rotate without damaging the wires. 6. Identify the wires in the 4-wire cable.
Grounding Junction box to a 9-wire remote transmitter or remote core processor Follow the steps below to connect the 9-wire cable between the sensor and the transmitter or core processor. 1. Prepare and install the cable according to the instructions in Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide. 2. Insert the stripped ends of the individual wires into the terminal blocks. No bare wires should remain exposed. 3. Match the wires color for color.
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 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 (for example, argon), locate the inlet lower than the outlet, so the purge gas will displace air from bottom to top.
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. Information on return procedures and forms is available on our web support system at www.micromotion.com, or by phoning the Micro Motion Customer Service department.
