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 Figur

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. � For sensors with a junction box or core processor, the limits in

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. Figure 9 Mounting an F-Series sensor Sensor Installation: F-Series 13

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). Figure

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. � A core processo
