Series IEFB Insertion Thermal Energy Meter

Field Adjustable, BACnet/Modbus® Outputs

The Series IEFB is a field-adjustable insertion thermal energy meter that useselectromagnetic technology to accurately and reliably measure fluid velocity andenergy consumption. The high accuracy IEFB is adjustable to fit pipe sizes from 4to 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 asingle unit. The LCD display provides clear readings of the meter’s values, includingtemperature and energy consumption, making it ideal for installation on chillers,boilers, and other heating and cooling applications. The high measuring accuracy andlong lifetime keeps annual operating costs at a minimum. In addition, it offers severaloutput options, including selectable BACnet MS/TP or Modbus® RTU communicationsprotocol over 2-wire RS-485 and standard analog, frequency, and alarm outputs.

Product Applications
