Series IEF Insertion Electromagnetic Flow Transmitter

Field Configurable, High Accuracy, BACnet or Modbus® Protocol

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" (101.6 to 914.4 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.

Dwyer Instruments, Inc. was recognized for excellence in product design in the 15th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News magazine. An independent panel of contractors acted as judges in the contest that had 98 entries. The company’s Insertion Electromagnetic Flow Transmitter was the Bronze Award Winner in the Testing and Monitoring product category. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.

Features

  • Field configurable, integral or remote setup displays (-LCD option or 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 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.
