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

ADDITIONAL SPECIFICATIONS

Applicable Pipe Material : Most popular plastic and metal pipes; i.e. Carbon steel, SS, copper, UPVC/PVDF, galvanized steel, mild steel, and brass*.

Applicable Pipe Size : 4 to 36″ (100 to 900 mm), sku dependent. See sku chart on catalog page.

Diameter Length Requirement :>10 upstream, >5 downstream.

Glycol : 0 to 100% display selectable.

*Brass fittings and pipe not for use with NSF Certified skus.

  • 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 sku 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.
  • NIST traceable pass/fail verification certificate 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.
