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.
