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˝ (102 to 914 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 congurable setup displays (-LCD integral option or remote 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 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 traceable pass/fail verication certicate included standard for Carbon Steel Schedule 40 pipes sized 4˝ (102 mm), 6˝ (150 mm), 8˝ (200 mm), and 10˝ (250 mm) with high accuracy option; 10˝ (250 mm) with standard option.
