Series IEF Insertion Electromagnetic Flow Transmitter

Field Configurable, High Accuracy, BACnet or Modbus® Protocol

A-IEF Remote Display is NOW AVAILABLE!

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.
