Series IEF Insertion Electromagnetic Flow Transmitter
Specifications - Installation and Operating Instructions
Shown with A-IEF-VLV-BR
accessory valve
The Series IEF Insertion Electromagnetic Flow Transmitter is an adjustable
insertion flowmeter featuring electromagnetic technology that accurately and reliably
measures fluid velocity in addition to providing several continuous signal outputs.
This series is specifically designed to offer superior performance paired with simple
installation and use. One unit is adjustable to fit pipe sizes from 4 to 36˝ (100 to
900 mm), and offers several output options including selectable BACnet MS/TP or
Modbus RTU communications protocol over 2-wire RS-485 in addition to the standard
®
analog, frequency and alarm outputs.
FEATURES/BENEFITS
• Field configurable setup displays (-LCD integral option or remote accessory
A-IEF-DSP) allow for ultimate flexibility by accommodating a variety of application
configurations with one model through multiple display configurations 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 changes in 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 certificate 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.
