1 Planning
1.1 Installation checklist
□Make sure that the hazardous area specified on the approval tag is suitable for the
environment in which the meter will be installed.
□Verify that the local ambient and process temperatures are within the limits of the
meter.
□If your sensor has an integral transmitter, no wiring is required between the sensor and
transmitter. Follow the wiring instructions in the transmitter installation manual for
signal and power wiring.
□If your transmitter has remote-mounted electronics, follow the instructions in this
manual for wiring between the sensor and the transmitter, and then follow the
instructions in the transmitter installation manual for power and signal wiring.
Table 1-1: Maximum cable lengths
Cable type To transmitter Maximum length
Micro Motion 4-wire All 4-wire MVD transmitters —1,000 ft (305 m) without
Ex-approval
—500 ft (152 m) with IIC

Signal (RS-485) 22 AWG (0.326 mm²) or larger 1,000 ft (305 m)
□For optimal performance, install the sensor in the preferred orientation. The sensor will
work in any orientation as long as the flow tubes remain full of process fluid.

□Install the meter so that the flow direction arrow on the sensor case matches the actual
forward flow of the process. (Flow direction is also software-selectable.)
1.2 Best practices
The following information can help you get the most from your sensor.
•There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe
upstream or downstream are unnecessary.
•If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward
through the sensor. Gases should flow downward.
•Keep the sensor tubes full of process fluid.
•For halting flow through the sensor with a single valve, install the valve downstream
from the sensor.
•Minimize bending and torsional stress on the meter. Do not use the meter to align
misaligned piping.
•The sensor does not require external supports. The flanges will support the sensor in
any orientation.
1.3 Temperature limits
Sensors can be used in the process and ambient temperature ranges shown in the
temperature limit graphs. For the purposes of selecting electronics options, temperature
limit graphs should be used only as a general guide. If your process conditions are close to
the gray area, consult with your Micro Motion representative.
Note
•In all cases, the electronics cannot be operated where the ambient temperature is
below -40 °F (-40.0 °C) or above 140 °F (60.0 °C). If a sensor is to be used where the
ambient temperature is outside of the range permissible for the electronics, the
electronics must be remotely located where the ambient temperature is within the
permissible range, as indicated by the shaded areas of the temperature limit graphs.
•Temperature limits may be further restricted by hazardous area approvals. Refer to the
hazardous area approvals documentation shipped with the sensor or available from the
Micro Motion H-Series Hygienic Coriolis Flow and Density Meters Product Data Sheet. For
further quesitons, contact customer service.

•The extended-mount electronics option allows the sensor case to be insulated without
covering the transmitter, core processor, or junction box, but does not affect
temperature ratings. When insulating the sensor case at elevated process
temperatures (above 140 °F (60.0 °C)), please ensure electronics are not enclosed in
insulation as this may lead to electronics failure.

1.4 Recommendations for hygienic and self-
draining applications
H-Series sensors are self-draining when installed in a vertical pipeline.
For optimal cleanability and drainability:
•If possible, install the sensor in a vertical pipeline with the process fluid flowing upward
through the sensor.
•If the sensor must be installed in a horizontal pipeline, drainage is accomplished by air
purge evacuation of the pipeline circuit.
•For clean-in-place (CIP) applications, Micro Motion recommends using the generally-
accepted flow velocity of at least 1.5 m/s for cleaning the sensor.
•The gap between the electronics housing and sensor body should be inspected
periodically. Manually clean this gap when necessary.
•Tri-clamp and DIN 11851 style process connections require special gaskets to comply
with EHEDG requirements for hygienic design.

2 Mounting
2.1 Mount the sensor
Use your common practices to minimize torque and bending load on process connections.
About this task
Tip
To reduce the risk of condensation problems, do not orient transmitters or sensor junction
boxes with their conduit openings pointing upward.
CAUTION
Do not lift the sensor by the electronics or purge connections. Lifting the sensor by
the electronics or purge connections can damage the device.
Figure 2-1: Mounting the sensor
Notes
•Do not use the sensor to support the piping.
•The sensor does not require external supports. The flanges will support the sensor in
any orientation.

2.2 Attach extended electronics
If your installation has a sensor with extended electronics, you will need to install the
extender onto the sensor case.
About this task
Note
Extended core processors are matched at the factory to specific sensors. Keep each core
processor together with the sensor with which it was shipped.
CAUTION
Keep the extender and feedthrough clean and dry. Moisture or debris in the extender
or feedthrough can damage electronics and result in measurement error or
flowmeter failure.
Procedure
1. Remove and recycle the plastic cap from the feedthrough on the sensor.
