2. Installation

Receiving/Inspection

• Unpack carefully, observe Electro-Static Discharge (ESD) precautions if handling the flow transmitter.

• Inspect for damage to the flow element and the flow transmitter.

• Verify that all items in the packing list were received and are correct.

• Verify the Delta R Data Sheet and the Instrument Information Sheet are present in the plastic page protector

found in the back of the manual.

If the above items are satisfactory then proceed with installation. If not, then stop and contact the FCI customer
service representative for instructions.

Packing/Shipping/Returns

These issues are addressed in Appendix C - Customer Service.

Factory Calibration Note

The flowmeter is factory calibrated to the flow range specified in the order. There is no need to perform any
verification or calibration steps prior to installing and placing the flowmeter in service.

Pre-Installation Procedure

Warning:

Caution:

Install the flowmeter with properly trained personnel only. Perform the installation according to
the current edition of the National Electrical Code. Ensure that all power is OFF. Any instances
where power is to be applied to the flowmeter will be noted in this manual. Where the
instructions call for the use of power, the operator assumes all responsibility for conformance to
safety standards and practices.

The flowmeter is not designed for weld-in-place applications. Never weld to process connection
or a structural support.

Damage resulting from moisture penetration of the local or remote enclosure is not covered by
product warranty.

The flow transmitter contains electrostatic discharge (ESD) sensitive devices. Use standard ESD
precautions when handling the flow transmitter. See below for ESD details.

Use Standard ESD Precautions

Use standard ESD precautions when opening an instrument enclosure or handling the flow transmitter. FCI
recommends the use of the following precautions: Use a wrist band or heel strap with a 1 megohm resistor connected
to ground. If the instrument is in a shop setting there should be static conductive mats on the work table and floor
with a 1 megohm resistor connected to ground. Connect the instrument to ground. Apply antistatic agents to hand
tools to be used on the instrument. Keep high static producing items away from the instrument such as non-ESD
approved plastic, tape and packing foam.

The above precautions are minimum requirements to be used. The complete use of ESD precautions can be found in
the U.S. Department of Defense Handbook 263.

Verify Serial Numbers

Verify that the local (flow element terminal strip) enclosure, remote enclosure and flow transmitter control circuit
serial numbers match. If they do not match, incorrect measurements will be made.

When multiple local enclosures are connected to one remote enclosure, each local enclosure serial number has a
suffix that represents the flow element number. For example, if two local enclosures are connected to a remote
enclosure, the local enclosure will have a base serial number of 123, then the first local enclosure would have the
serial number 123-1. The second local enclosure would have the serial number 123-2.

Prepare or Verify Flow Element Location

The flow element location should have been previously determined before the time of order. Mounting the flow
element in a position different than originally determined may cause reading errors.

The shape of the flow element is cylindrical with a diameter of 2.00 inches (50.8 mm). The flow element length
(U-length) is customer specified. The recommended diameter for the clearance hole needed to mount the flow
element is 2.16 inches (54.8 mm).

For the best performance, prepare an additional support for flow elements that are longer than 2 feet (61 cm). See
Figure A-3 for the recommended connection.

Verify Dimensions

Verify the customer specified flow element U-length and instrument mounting interface dimensions are correct for
the application. Compare the instrument hardware, Appendix A and the process interfaces for fit.

Verify Flow Direction for Flow Element Orientation and Placement

The flow element comes with a FLAT area machined on the flow element near the enclosure. There is a FLOW
ARROW etched in the FLAT. The FLOW ARROW indicates the direction of flow. See Figure 2-1 for details.

Figure 2-1. Flow Element Showing FLAT Area

Align the flow element so the FLAT is parallel to the direction of flow. Also, align the FLOW ARROW to point in
the direction of flow. Failure to correctly install the flow element will reduce the accuracy of the flowmeter.

Install Flow Element

Install the flow element for the type of process connection used. Follow one of the next paragraphs to install the
flow element. If applicable, connect the end of the flow element to a recommended mechanical support. See
Figure A-1 for the end connection.
