product series features
- Flexible, field configurable setup displays (LCD integral option or remote accessory A-IEF-DSP) accommodate a variety application configurations. Application information is display selectable and includes 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 and/or viscosity
- The Setup Wizard and installation tool are simple to use, providing quick and precise installation
- Accessory setup kit A-IEF-KIT comes with a thickness gauge and measuring tape to ensure exact installation depth
- The meter has no moving parts and electrodes that discourage fouling, which gives the meter a long lifecycle and minimizes the need for maintenance
- Hot-tap isolation valve accessories allow for easy installation and removal in operational systems without system downtime

Series Description
The Dwyer IEFB Series is a field-adjustable, insertion thermal energy meter that uses electromagnetic technology to accurately and reliably measure fluid velocity and energy consumption. The flowmeter is simple to install and is adjustable to fit pipe sizes from 4 to 10Ë (100 to 900 mm). The Dwyer IEFB Series incorporates a temperature meter and a calculator into a single unit. The LCD display provides clear readings of the meter's values, including temperature and energy consumption, making it ideal for installation on chillers, boilers, and other heating and cooling applications. In addition, it offers several output options, including selectable BACnet MS/TP or Modbus® RTU communications protocol over two-wire RS-485 and standard analog, frequency, and alarm outputs. Furthermore, the superior performance of the IEFB keeps annual operating costs at a minimum thanks to its combination of high measuring accuracy and long lifetime.
