The Series IEF Insertion Electromagnetic Flow Transmitter is an adjustable

insertion owmeter featuring electromagnetic technology that accurately and reliably
measures uid velocity in addition to providing several continuous signal outputs.
This series is specically designed to offer superior performance paired with simple
installation and use. One unit is adjustable to t pipe sizes from 4 to 36˝ (101.6 to

914.4 mm), and offers several output options including selectable BACnet MS/TP or

RTU communications protocol over 2-wire RS-485 in addition to the standard

Modbus
analog, frequency and alarm outputs.

FEATURES/BENEFITS

• Field congurable, integral or remote setup displays (-LCD option or accessory
A-IEF-DSP) allow for ultimate exibility by accommodating a variety of application
congurations with one model through multiple display congurations i.e. pipe
size, pipe material, liquid type, analog output, pulse/frequency output, alarm outputs,
communication outputs, damping, and calibration factor.

• High performance accuracy is maintained through temperature, density or viscosity.

• Setup Wizard and installation tool are simple to use allowing for quick and precise
installation.

• Accessory setup kit A-IEF-KIT ensures exact installation application depth with
included thickness gage and measuring tape.

• Long Life Cycle and minimal maintenance requirements with no moving parts to
wear or break and electrodes that discourage fouling.

• Isolation valve accessory options allow for installation in operational systems via
hot-tap kit or easy removal without system downtime.

• NIST calibration certicate included standard for Carbon Steel Schedule 40 pipes
sized 4˝ (100 mm), 6˝ (150 mm), 8˝ (200 mm), and 10˝ (250 mm) with high accuracy
option.

INSTALLATION

1. To prepare the meter for installation, mount the provided alignment scale to the
side of the meter with the two provided thumbscrews. The thumbscrews are to be
inserted through the alignment scale slots and into the holes in the side of the lid
as shown in Figure 4, nger tighten only. Be sure to orient the alignment scale as
shown in gure below. Actual scale setting determined in next step.

RECOMMENDED TOOLS

• (2) 12˝ (300 mm) adjustable wrenches

• (1) 12˝ (300 mm) pipe wrench

SETUP

Selecting Installation Location

1. Although the unit may be installed in any orientation, the ideal mounting position
is on the side of the pipe (2 o’clock or 10 o’clock position) as this generally
minimizes possible air or sediment interference with the Series IEF.

Note: When installing a unit with an integral display select an installation
location that allows for clear viewing of the display and proper earth ground.

Insert the IEF in a pipe via a threaded Tee, Saddle, or welded integrally
reinforced branch connection outlet tting.

If a Hot-Tap option is required, use a 1-1/4˝ valve kit with proper mounting
hardware available in Model A-IEF-VLV-BR or A-IEF-VLV-SS. A 1˝ (25.4 mm)
hole in the pipe is required for proper installation.

2. Locate the conguration tag attached to the Series IEF to identify the value of
the alignment scale setting. Position the alignment scale such that the scale
setting is lined-up with the seam of the enclosure as shown in Figure 4. Minor
scale marks are in 1/20ths Securely tighten the thumbscrews.

3. Refer to Preparing the Unit for Installation section.

For Field Congurable Models

2. For eld conguration a display is required (-LCD option or accessory A-IEF­ DSP) and needs to be powered via normal eld wiring or with the AC wall adapter
accessory A-IEF-PA ( A-IEF-DSP and A-IEF-PA are also available in the
accessory setup kit A-IEF-KIT).

3. When using the AC wall adapter and the cable is supplied, connect the red
(positive +) and black (common -) wires of the cable bundle marked “A” to the
open terminals of the AC wall adapter. This will provide temporary power to the
meter to complete the installation set up.

4. For eld wiring refer to the wiring chart tag attached to the Series IEF to identify
the terminal block pins for positive (+) and common (-) connection.

5. Unscrew the four captured cover screws using the supplied 3 mm Allen wrench
to remove and set aside enclosure cover.

6. Insert one connector of the ribbon cable supplied in the setup kit into the
connector labeled “Display” in the middle of the unit. Be sure to orient the keying
feature/tab. See Figure 5 below:

FEA

Preparing the Unit for installation (Refer to Figure 7)

1. Apply appropriate sealant to the process collet (5) threads such as application
suitable sealant tape or paste.

2. Install the process collet (5) in valve (6) then tighten by hand.

3. Tighten the process collet (5) with a wrench using the hex geometry until snug.

NOTICE

4. Slowly open the valve handle (7) checking for leaks.

5. If leaks occur around threaded connections, close the valve and tighten those
connections.

Use two wrenches, one to hold the valve and another wrench to
turn the process collet.

A depth and ow alignment installation tool is provided to ensure proper depth insertion
and ow alignment. To set the insertion depth verify the alignment scale has not moved
from its original setting based on the alignment scale value set previously.

Loosen compression nut (4) to allow the shaft (3) freedom to travel up and down and
rotate inside the process collet (5).

Install Depth and Alignment Rods

1. Remove alignment rods from sides of alignment scale by sliding them out.

2. Insert the two rods into the alignment scale as shown.

GROUNDING

Metallic Pipe

For proper operation the instrument must be earth grounded.
Connect a ground wire to meter housing via the ground lug on the housing collet.
Connect the ground wire to a known earth ground.
If the pipe is grounded, connect the ground wire to the metal pipe using suitable
devices such as grounding clamps.

POWER SUPPLY

Choose a power supply with a voltage and current rating sufcient to meet the power
specications under all operating conditions.
If the power supply is unregulated, make sure the output voltage remains within the
required voltage range under all power line conditions.
