4 Determining a Location Figure 3 T -Series sensor with junction box Step 1 Determining a Location Choose a location for the sensor based on the requirements described in th is section. The foll o wing general guidelines can help you select an appropriate locatio n for the sensor . Full flow tubes For op timal performance, the sensor t ubes should [...]

5 Determining a Locati on Figure 4 T -Series sensor ambient an d process temperat ure limits Hazardous area approv als may impose additional limits on ambient and process temperature. For the A TEX “T” rating, refer to the A TEX documentation shipped w ith the sensor or av ailable on the Micro Motion web site at www .micromotion.com . UL and CS[...]

6 Determining a Location Maximum wiring distances If the transmitter is mounted remote ly from the sensor , the maximum di stance between the sensor and transmitter depends on cable type. See T able 2. Pipe run Micro Motion sensors d o not require a straight run of pipe upstream or downstream. Va lv e s After the sensor and transmitter ha ve been i[...]

7 Orienting the Sensor Step 2 Orienting the Sensor The sensor will function proper ly in an y orientation if the sensor tube s remain f illed with process fluid. Micro Motion recommends orienting the sensor in a v ertical pipeline, with process flu id flo w ing upwa rd through the sensor (see Figure 5). Figure 5 Recommended se nsor orientation Self[...]

Man ually clean this gap when necessary . • The ASME Bioprocess Equipment Standard (ASME BPE-19 97), section SC-3.12.1, includes recommendations re garding ho w to install process piping to ensure[...]

9 Mounti ng the Sensor Step 3 Mounting the Sensor Use your commo n practices to minimize to rque and bendi ng load on process connections. T o reduce the risk of condensation or excessiv e moisture , the conduit opening should not point upward (if possible). The conduit opening of the junction box or core processo r can be rotated freely to facilit[...]

10 Wiring Step 4 Wiring Hazardous area installations If you are installing the sensor in a hazardous location, verify that the hazardous classif ication information printed on the sensor tag matches the en vironm ent in which the sensor will be installed. Failure to comply with the requirements f or intrin sic safety in a hazardous area could resul[...]

14 Grounding Step 5 Grounding The sensor can be grounde d via the piping if the joints in the pipeline are ground- bonded. If the sen sor is not grounded via the piping, connect a groun d wire to the in ternal or exter nal grounding scre w , which is located on the core processo r housing or junction box. Improper gr ounding can cause measurement e[...]
