Workshop: Flow and heat measurement at high temperatures

Industrial need and practice

Hybrid meeting (web and physical) on March 23/24, 2021 at PTB in Berlin, Germany

Note: Due to the present infection situation with SARS-CoV2, most probably the event will take place online only.


Recent measurements in high heated water circuits with medium temperatures above 90 °C with heat meter’s flow sensors are characterized to the state-of-the-art with inadequate knowledge of their performances and stabilities.

Recent practice in execution of conformity assessments are estimations of the specific behaviour of the instrument’s accuracy with respect to measuring results on basis of the standardized EN 1434 medium temperatures at test points on 20 °C, 50 °C and 85 °C. At higher medium temperatures with e.g. 120 °C, calculations of measuring deviations and stabilities are only founded on extrapolations of the specific error curve via the tested temperature points.     

For confidence of the correctness and stability of the flow sensor’s capacities at higher medium temperatures, new test rigs and technologies are necessary and shall also be achieved during research and development for manufacturing, user applications and conformity assessments. The process industry, which measures various fluids at high temperatures, could also benefit from such test systems.

Call for participation and lectures

EMATEM e.V. and PTB would like to discuss with you the state of recent knowledge as well as present and future requirements for flow measurements at high temperatures in water circuits and other fluids in processes with the topics

- economic requirements,

- user applications,

- research, development, testing and manufacturing

- test rigs and technologies.

Discussion will also take place in special sessions.


For topic and presentation proposals, please contact Dr. Jürgen Rose (phone +49 30 3481 7250) or Dr. Karl Jousten (+49 30 3481 7262).
