DWYER IEF Series Insertion Electromagnetic Flow Transmitter

The Dwyer IEF Series insertion electromagnetic flow transmitter accurately and reliably measures fluid velocity of compatible clean or dirty non-coating, conductive liquids in addition to providing several continuous signal outputs. One unit is adjustable to fit pipe sizes from 4 to 36 inches (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.

Field configuration of the Dwyer IEF Series insertion electromagnetic flow transmitter can be done via the integral LCD (optional) or remote setup display (A-IEF-DSP; sold separately) and offers flexibility by accommodating a variety of application configurations with one model through multiple display configurations including pipe size, pipe material, liquid type, analog output, pulse/frequency output, alarm outputs, communication outputs, damping, and calibration factor.
