Dwyer Instruments has recently released its Series IEFB 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 250mm), while the standard accuracy IEFB fits pipe sizes 4 to 36" (100 to 900mm). The flowmeter is simple to install and incorporates a temperature meter and an energy calculator in one. The LCD display provides precise 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 or Modbus RTU communications protocol over 2-wire RS-485 and standard analog, frequency, and alarm outputs. Features/benefits: • Flexible, field configurable setup displays accommodate a variety of application configurations • 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 • The meter has no moving parts and electrodes that discourage fouling, which gives the meter a long life‑cycle • Hot-tap isolation valve accessories allow for easy installation and removal in operational systems without system downtime.
