We are offering our successful flow seminar again in 2023. Register now and benefit from our early bird discount (until 31th of May 2023).

This seminar is designed for those interested in purchasing, calibration, engineering, and all users of flowmeters.

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

We are looking forward to meeting you!

TrigasFI Laboratory – Flow Specialists

Welcome to the TrigasFI calibration laboratory, your address for flow measurement and calibration!

JUST FLOW. Liquid and Gas.
The first Flow Laboratory to be accredited for both liquid and gas flow measurement in Europe.

Our high standards and extensive knowhow in the field of Flow Measurement are obvious from the first glance. Europe-wide, we were the first Calibration Laboratory to be accredited for both Liquid and Gas Flow Calibrations. The accreditation was done by the German Accreditation authority DAkkS according to DIN EN ISO/IEC 17025.  Finally we are still the only one that specializes exclusively in Flow.

We are not a “jack of all trades”, we are dedicated to FLOW and it shows. The competence of TrigasFI Calibration Laboratory is the result of our more than 30 years of dedication to Flow. Since that time, TrigasFI is committed to advancing the Flow Measurement and Calibration state of the art. Our quality is guaranteed by our DIN EN ISO 9001 TÜV certification and DAkkS accreditations.

Our Services

Flowmeters such as Turbines, Sonic Nozzles, Magnetic, Positive Displacement (Gear and Oval Gear) Coriolis, LFEs (Laminar Flow Elements), Thermal (MFC and MFM) etc. are calibrated at the TrigasFI Calibration Laboratory. The calibrations are performed with actual viscosities or with real gas according to the strict quality standards of DIN EN ISO 17025. With more than 15 primary calibrators with an accuracy of up to 0.03%, TrigasFI is equipped to handle practically any flow range.

In order to minimize setup and downtime costs, TrigasFI also offers onsite calibration service, in which an experienced calibration technician takes care of the adjustment, repair or even replacement of a not optimally functioning flowmeter.

Our service and product portfolio is complemented by our own calibrator and test stands construction, as well as our manufacturer-independent consultant services. Offered are, among others, Turbine flowmeters and Mass Flow Meters and Controllers.

By opting for TrigasFI, you are not only assured of the services of a versatile and innovative laboratory. But first and foremost you can expect precise and meaningful flow measurement values. Because wherever possible, we consider all operating and environment parameters. We use, for example, the original media for all measurements. Because diesel behaves in a different way than water, helium unlike propane. Temperature, pressure, viscosity – all have an impact on the measurement result. So if your need is for exact flow measurement values, we look forward to hearing from you.
