Safety Information
WARNING
• Only qualified professionals equipped with the necessary required trade skills
should install, remove or service this product in any way. Failure to follow the
proper installation procedures could lead to death or permanent injury.
• This product is intended to be installed in pressurized pipe applications. In this
event, product will be under pressure, caution should be taken to properly vent
system prior to installation or removal of the unit. Failure to do so could result in
equipment damage and/or serious bodily injury.
CAUTION
• Refer to Model Chart and Specifications for the applicable options to your unit.
• Ensure the unit is sufficiently grounded as stated in this bulletin.
• Depressurize and vent systems without Hot-tap valve prior to installation or
removal.
• Confirm the Series IEF wetted material is chemically compatible with process
media prior to installation and use.
• Do not exceed maximum temperature and pressure specifications.
• Wear appropriate personal protective equipment during installation, removal and or
service of the unit.
• Altering the product construction in any way may adversely affect product operation
and voids warranty.
• Prior to attempting to wire or service the Series IEF disconnect from power.

OPERATING PRINCIPLE
• Per Faraday's Law of electromagnetic induction, a voltage is induced in a conductor
when it passes through a magnetic field, and the induced voltage will be directly
proportional to the velocity of the conductor.
• The Series IEF Flow Transmitter generates pulsating magnetic fields in the probe
to induce a voltage into a conductive fluid flowing through the pipe.
• Electrodes located on the probe measure the induced voltage. Electronics and
firmware within the enclosure convert the voltage to velocity and flow rate while
using various outputs to convey the data to connected systems (i.e. display
devices, data acquisition systems, or BTU meters).

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. It is not
reccomended to mount the unit below the pipe (6 o'clock position).
NOTICE 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 fitting.
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.
