Flexim™ FLUXUS G631 EE - Portable Clamp-on Ultrasonic Flow and Energy Meter for Gases and Liquids

The FLUXUS G631 EE is a portable transit-time ultrasonic flow meter for all kinds of gases and liquids with an integrated function for energy flow calculation.

The Flexim FLUXUS G631 EE is the perfect multi-tool for energy managers. It combines portable, non-intrusive flow and thermal energy measurement for natural gas, compressed air, technical gases, and liquids.
The ultrasonic transit-time principle provides a great dynamic flow range and enables detection of even very small leaks, starting at flow velocities as low as 0.01 m/s (0.03 ft/s). Surveys of compressed air systems, consumption verification, and check metering have never been simpler.
The integrated thermal energy calculation enables quick and easy setup in HVAC systems, chillers, and cooling towers. The Dynamic Gas Meter function allows compressibility correction for varying or unknown natural gas compositions.
With the FLUXUS 631 family, Emerson also offers portable flow and energy meters for steam.
