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.
