STEP 1.Determining a location
The sensor may be located anywhere in the process line, as long as the
following conditions are met:
•Before operation, you must be able to stop flow through the sensor.
(During the zeroing procedure, flow must be stopped completely, and
the sensor must be full of process fluid.)
•During operation, the sensor must remain full of process fluid.
•The sensor must be installed in an area that is compatible with the
classification specified on the sensor approvals tag (see Figures 1- 4).
Choose a location for the sensor based on the requirements described in
this section.

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 installing D,
DT, and DL sensors as shown in Figure 5.
Flow direction arrow
The sensor has a flow direction arrow (see Figures 1-4) to help you
configure the transmitter for flow direction. Process fluid flowing in the
direction opposite to the flow direction arrow may cause unexpected
transmitter output unless the transmitter is configured appropriately. For
instructions on configuring the transmitter’s flow direction parameter,
refer to the transmitter instruction manual.

STEP 3.Mounting the sensor
D and DT sensors
Use your common practices to minimize torque and bending load on
process connections.
Figure 6 illustrates how to mount a D and DT
sensor. If possible, install wiring with the conduit opening pointed down
to reduce the risk of condensation or excessive moisture in the junction
box.
Figure 6.Mounting a D and DT sensor
CAUTION
Using the sensor to support piping can damage the
sensor or cause measurement error.
Do not use the sensor to support pipe.
9
DL sensors
To ensure optimal performance of the DL sensor, follow these guidelines:
•Attach piping to a stable structure in at least one location downstream
and at least one location upstream from the sensor. Put supports as
close as possible to the process connections. Supports should be
attached to the same structure. See Figure 7.

•If multiple sensors are installed in series or in parallel, piping to each
sensor must have separate supports. Clamp at least two fixed pipe
supports on piping between sensors installed in series.
•Flexible piping may be installed to minimize piping vibration
transmitted to the sensor. Piping immediately adjacent to the sensor's
process fittings must be rigid.
10
After process piping has been installed and properly supported, refer to
Figure 8 and follow these guidelines when installing the sensor:
•Install the sensor with user-supplied mounting legs, bolts, and lock
washers (six 1/4 inch-20 UNC for a DL65 or DL100 sensor; two 1/4
inch-20 UNC and four 3/8 inch-16 UNC for a DL200 sensor).
•Use appropriate user-supplied gaskets between process fittings on the
sensor and process piping.

STEP 4.Wiring the sensor to the transmitter
WARNING
Failure to comply with requirements for intrinsic
safety in a hazardous area could result in an
explosion.
• Make sure the hazardous area specified on the sensor
approvals tag is suitable for the environment in which
the sensor is installed. See Figures 1-4.
• For installation in an area that requires intrinsic safety,
refer to Micro Motion UL, CSA, SAA, or ATEX
documentation, shipped with the sensor or available
from the Micro Motion web site.
• For hazardous area installations in Europe, refer to
standard EN 60079-14 if national standards do not
apply.
CAUTION
Failure to seal the sensor junction box housing and
transmitter housing could cause a short circuit,
which would result in measurement error or
flowmeter failure.
• Ensure integrity of gaskets and o-rings.
• Install drip legs in conduit or cable.
• Seal all conduit openings.
12
Model D sensor junction box
Most Model D sensors are shipped with a junction box for wiring. For
Model DT sensors, see Model DT conduit and junction box below. For
Model D and DL sensors:
•If not already installed, install the junction box on the sensor,
following the wiring instructions on the junction box.
•If possible, install wiring with the junction box opening pointed
down, or with a drip leg in the conduit or cable, to reduce the risk of
condensation or excessive moisture in the junction box. See Figure 9.
•Next, follow the guidelines in 9-wire cable wiring to wire the sensor
to the transmitter.
Figure 9.Model D sensor junction box
3/4" NPT female

Model DT conduit and junction box
DT sensors come with a 3-foot (1 meter) pigtail of pre-installed cable and
a 3-foot (1 meter) piece of conduit that needs to be fitted over the preinstalled cable. Refer to Figure 10.
•Slide the conduit over the pre-installed cable.
•Screw the conduit fitting end into the sensor.
13
The other end of the conduit can be connected to a user-supplied junction
box or directly to a transmitter.
•If the conduit is connected to a user-supplied junction box, connect the
wires to the terminals on the junction box. If possible, install wiring
with junction box openings pointed down, or with drip legs in the
conduit, to reduce the risk of condensation or excessive moisture in
the junction box. Next, connect the 9-wire cable from the junction box
to the transmitter by following the instructions in 9-wire cable wiring.
•If the conduit is connected directly to a transmitter, refer to the wiring
instructions in the transmitter Quick Reference Guide.

9-wire cable wiring
Follow the steps below to connect the 9-wire cable between the sensor
and the transmitter.
1. Prepare 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.
•For D and DL sensors, match the wires color for color. For wiring
at the transmitter, refer to the transmitter Quick Reference Guide.
•For DT sensors, connect the sensor cable wires to the junction
box terminals. Then, connect the 9-wire cable to the junction box
terminals, matching the colors of the wires to the numbers of the
DT sensor terminals, as indicated in Table 4. For wiring at the
transmitter, refer to the transmitter Quick Reference Guide.
3. Tighten the screws to hold the wires in place.
4. Ensure integrity of gaskets, then tightly close and seal the
junction box cover and all housing covers on the transmitter.
• Ground the flowmeter to earth, or follow ground
network requirements for the facility.
• For installation in an area that requires intrinsic safety,
refer to Micro Motion UL, CSA, SAA, or ATEX
documentation, shipped with the sensor or available
from the Micro Motion web site.
• For hazardous area installations in Europe, refer to
standard EN 60079-14 if national standards do not
apply.
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 sensor grounding screw (see Figures 1-4) or the
junction box grounding screw.
If national standards are not in effect, follow these guidelines:
•Use copper wire, 14 AWG (2,5 mm²) or larger wire size for
grounding.
•Keep all ground leads as short as possible, less than 1 ohm impedance.
•Connect ground leads directly to earth, or follow plant standards.
Refer to the transmitter Quick Reference Guide for instructions on
grounding the transmitter.

Etape 1.Choix de l'emplacement
Le capteur peut être installé n’importe où sur la ligne du process, à
condition que les points suivants soient respectés :
•Une vanne d’arrêt parfaitement étanche doit être installée en aval du
capteur (au cours de la procédure d’auto-réglage du zéro, le débit doit
être complètement arrêté et le capteur doit demeurer rempli de fluide).
•Lorsque le débitmètre est en exploitation, les tubes du capteur doivent
toujours demeurer remplis du fluide du process.
•Le capteur doit être installé dans une zone qui est compatible avec le
certificat de conformité indiqué sur la plaque signalétique de
certification (voir les figures 1 à 4).
De plus, le choix de l’emplacement du capteur doit répondre aux
contraintes suivantes :
Limites de température

ETAPE 2.Orientation du capteur
Le capteur fonctionnera correctement dans n'importe quelle orientation à
condition que les tubes de mesure restent constamment remplis du fluide
à mesurer. Micro Motion recommande d’installer le capteur comme
illustré à la figure 5.
Sens d'écoulement
Une flèche est gravée sur le corps du capteur pour permettre la
configuration du paramètre « sens d’écoulement » du transmetteur (voir
les figures 1-4). Si le fluide s'écoule dans la direction opposée à la flèche,
les sorties du débitmètre risquent de ne pas réagir comme prévu si le
débitmètre n'est pas configuré correctement. Pour configurer le paramètre
« sens d’écoulement » du transmetteur, consulter le manuel d'instructions
du transmetteur.
