Calibration of Mass and Volume Flows

Drosselgalerie auf Labortisch mit Druckregler im Hintergrund

The calibration of mass and volume flows is one of the core competences of TetraTec Instruments GmbH. We are one of the leading laboratories in Europe, particularly in the areas of measurement uncertainty, throughput times and measuring range coverage.

With an accredited measuring range of over 1:80,000,000,000 (80 billion), TetraTec Instruments has by far the largest continuous range coverage of volume and mass flow measurement in Europe. From the smallest volume measurements in the µL range to calibrations at 10,000 m³/h, we can fulfil (almost) all demands in the field of air gas measurement.

As a throughput laboratory, we do mostly not assign specific delivery dates, but process incoming orders continuously and usually within less than 15 business days. Thanks to various overlapping procedures and standards, we are not only able to carry out regular internal comparative tests of our equipment, but can also determine the best possible measurement uncertainty according to customer requirements.

Note:

The accreditation of the TTI laboratory also extends to the calibration of volumetric bodies through a summative measurement of a volumetric flow. As long as an examination within the accredited flow range is possible, we are also able to determine the traceable volume of a body.

Here you find information on the possible measurement ranges for DAkkS-accredited calibrations and factory calibrations.
