Measurement of Thermal Energy
Flow rate measurement of thermal energy on clean room HVAC systems
Non-Intrusive Monitoring of Clean Room HVAC Thermal Energy
Clean room HVAC systems in life sciences and other industries are inherently energy-intensive due to the high air exchange rates, filtration systems, and stringent climate controls required to maintain their pristine conditions. This makes the optimization of thermal energy management even more critical. By continuously monitoring and adjusting the HVAC system, facilities can enhance energy efficiency, reduce operational costs, and maintain regulatory compliance. Effective thermal energy management ensures a consistent, contamination-free environment, essential for high-quality life sciences outcomes while mitigating the significant energy demands of these facilities.

The Flexim FLUXUS F532 TE is a compact thermal energy meter with integrated heat flow calculation for water and all water-glycol mixtures. The FLUXUS F532 Thermal Energy is specially designed for heating and cooling measurements in industry and building applications. Based on the established transit time difference method, the volume flow is measured non-intrusively with ultrasound, and the supply and return temperatures are registered via 2 temperature inputs. Totalizers for total thermal energy are also included. Offering USB and LAN interfaces and serves the common communication interfaces Modbus TCP, Modbus RTU, BACnet MS/TP, BACnet IP and M-Bus.
- Non-intrusive thermal energy meter.
- Traceable factory calibration according to PTB.
- Paired temperature sensors and heat quantity calculation according to EN 1434.
The portable Flexim FLUXUS F601 Energy is specially designed for temporary heating and cooling Thermal Energy measurement, with all measurements - Flowmeter, Temperature, and BTU computer, contained in one device. Temperature and BTU calculations are done in accordance with EN 1434 Thermal Energy meter standard. The F601 Energy measures the volumetric flow rate non-intrusively via its clamp-on ultrasonic transducers. Simultaneously, temperature probes monitor the temperatures at the supply and return lines of the heating or cooling system. From the temperature difference as well as the measured volume flow rate and the physical media parameters (liquid enthalpy data stored in the meter), the heating or cooling performance is calculated.
- Portable and non-intrusive flow and thermal energy meter for liquids.
- Non-intrusive measurement for precise bi-directional thermal energy flow rates.
- Ideal for inner pipe diameters ranging from DN6 to DN6000.
The Flexim FLUXUS F721TE is specially designed for heating and cooling Thermal Energy measurement, with all measurements - Flowmeter, Temperature, and BTU computer, contained in one device. Calculations are done in accordance with EN 1434 Thermal Energy meter standard and the F721TE measures the volumetric flow rate non-intrusively via its clamp-on ultrasonic transducers. Simultaneously, temperature probes monitor the temperatures at the supply and return lines of the heating or cooling system - either non-intrusively with clamp-on sensors or by use of insertion temperature probes. It can be equipped with two measurement channels to measure two pipes simultaneously and allow complete monitoring and accurate measurements.
