TrigasFI Seminar Flow Measurement and Calibration

Liquids and gases

English: 19th – 21st of  September 2023 in Kranzberg/Freising/Germany
German: 26th – 28th of September 2023 in Kranzberg/Freising/Germany

Seminar fee: 1.750 € (excl. VAT) per seminar and participant

At TrigasFI, we calibrate, adjust and program thousands of flowmeters every year. As a result, we have gained a deep and exceptional knowledge of the characteristics of many flow measurement principles. We know how best to calibrate, install and operate them for the best possible accuracy and reliability. We are happy to share this knowledge with our customers through our training courses, seminars and on-site consultations.

This seminar is aimed at interested parties in the areas of purchasing, calibration, engineering and all users of flow meters.

It is designed as a neutral, manufacturer-independent seminar. The focus is on the physical fundamentals, the operation of modern flow measurement techniques, the theory and technology of calibration as well as metrological traceability.


The speakers in this seminar are specialists from the R&D and application departments of various market leaders in the field of flow measurement technology.
