Series IEFB Insertion Thermal Energy Meter
Field Adjustable, BACnet/Modbus® Outputs
The Series IEFB is a field-adjustable insertion thermal energy meter that uses electromagnetic technology to accurately and reliably measure fluid velocity and energy consumption. The high accuracy IEFB is adjustable to fit pipe sizes from 4 to 10" (100 to 250 mm), while the standard accuracy IEFB fits pipe sizes 4 to 36" (100 to 900 mm). The IEFB 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. The high measuring accuracy and long lifetime keeps annual operating costs at a minimum. In addition, it offers several output options, including selectable BACnet MS/TP or Modbus® RTU communications protocol over 2-wire RS-485 and standard analog, frequency, and alarm outputs.
