FLUXUS® F704 Thermal Energy

The FLUXUS® F704 Thermal Energy is a non-invasive flow meter, specially designed for heat and cold quantity metering within industrial environments. It is suitable for hazardous area approved variants, such as ATEX, IECEx Zone 2. This flow meter accurately measures volumetric flow rates non-invasively via Flexim’s breakthrough clamp-on ultrasonic transducers.

The FLUXUS® F704 Thermal Energy contains two measurement channels, which offers the following benefits:

  • Allows for a complete energetic monitoring of a heat exchanger
  • Simultaneously measures at two heat- or cold carrying lines
  • Allows for accurate measurements even at strongly disturbed flow profiles

Benefits of the FLUXUS® F704 Thermal Energy

  • Robust measurement from outside of the pipe
  • Virtually unlimited application range – even at extreme applications (from -190 °C uo to +650 °C)
  • Accurate thermal energy measurement due to:

– Paired and traceable calibrated ultrasonic transducers

– Paired and traceable calibrated temperature sensors (acc. to DIN EN 1434-1)

  • Extremely high measuring dynamics
  • Simple, cost-effective retrofitting without any disruption to supply
  • Secure storage of measuring data


Thermal Energy Meters

Flexim’s permanent or portable ultrasonic Thermal Energy meters allow for an easy determination of the thermal energy flow within a building. FLUXUS Thermal Energy meters accurately measure temperature measurements at the inlet and outlet of a system from outside of the pipe wall, being virtually maintenance free. From heat delivery between central heating plants, to real estate end-users or heat transfer flows in industrial processes, controlling and balancing the flow of energy is crucial for energy and cost savings.
