Product information

The Dwyer Series IEFB is an insertion thermal energy meter that combines flow measurement, temperature measurement and energy calculation in a single device. Model IEFB-GN-10-R10-COM-LCD is configured for pipe sizes greater than 10 to 36 inches (250–900 mm), with a 1" male NPT process connection, 10 ft PT temperature sensors with hot-tap thermowells, BACnet MS/TP or Modbus® RTU communication and an integral LCD display.

✔ Suitable measurement accuracy: The G configuration provides ±1% FS standard accuracy for pipe sizes greater than 10 to 36 inches (250–900 mm)

✔ Flow and energy measurement: Integrates a flow sensor, two PT temperature sensors and an energy calculator into a single device

✔ Flexible BMS communication: Supports BACnet MS/TP or Modbus® RTU over 2-wire RS-485, with protocol selection available from the display

✔ Integral LCD display: 2 x 2 inch (50 x 50 mm) graphic LCD provides clear readings and allows device configuration from the display

✔ Integrated temperature sensing: The R10 configuration includes two 10 ft (3 m) PT temperature sensors with hot-tap thermowells for supply and return temperature measurement

✔ No moving parts: Electromagnetic technology minimizes mechanical components that can wear, while the electrodes are designed to discourage fouling

✔ HVAC and energy management applications: Suitable for monitoring chiller performance, boilers, chilled water, condenser water, heating water and energy cost allocation
