Calibration of Flowmeters

for air and real gases

Gas Flowmeter Calibrations

TrigasFI performed more than 100,000 liquid and gas flowmeter calibrations over the past 30 years. We are one of few laboratories able to calibrate with actual viscosities and real gases. Therefore, we are ensuring a performance which is representative of actual operating conditions. Thanks to our experience, you can be sure that your flow meter will be optimally calibrated and adjusted. A properly calibrated device can often replace having to invest in new hardware.

Certified Quality

Gas Flowmeter Calibrations – TrigasFI is DAkkS ISO 17025 accredited and can provide DAkkS certification for practically all Liquid and Gas Flow calibrations performed in our lab. Specialty flow instruments and one-of-a-kind devises are tested routinely at TrigasFI. The list includes test leaks, Vehicle Body Leak systems, Aircraft and Industrial Gas Turbine components, etc.

Factory authorized Calibration Service for Alicat Flowmeters and Controllers

Our technicians are factory trained to perform Calibrations of Alicat Flowmeters and Controllers. We are providing most simple repairs and have full access to factory services for the more complicated ones as well. Fast turnaround and compliance to factory specifications is guaranteed.

What does Trigas do differently?

Our employee list includes experts with previous experience with well known flowmeter manufacturers.
Our calibration specialists receive periodic training as part of cooperation programs we have in place with many flowmeter manufacturers.
Combining our expertise with the use of primary and secondary standards of different operating principles, we offer the best calibration precision among DAkkS accredited calibration laboratories.

We are impartial! TrigasFI is not associated with any flowmeter manufacturer. Being an Independent DAkkS laboratory ensures unbiased, reliable calibration results.

The target turnaround time for calibrations is five work days. Depending on workload, we are sometimes challenged to maintain adherence to this target, but since we know how important it is to avoid process interruptions, for emergencies we also offer a 24-hour service, and when the need is dire, even calibrate-while-you-wait service.

We will gladly organize pick up and delivery of your sensitive equipment. Depending upon location this is done by means of our own driving service or by our transport partners. Pick Up Service is available.

Ultra-fast flow calibration with free-of-charge slot reservation

Let us schedule your calibrations before the flowmeters arrive at our premises

To minimize your downtime and offer you the shortest possible turnaround times for calibration of your flowmeters, TrigasFI GmbH offers free Slot Reservation (pre-planning). This enables us to complete your orders faster, individually and in high quality.

The advantage of reserving a slot for the calibration of your flowmeter is that you minimize the time during which the device cannot be used on your premises. This is because Slot Reservation gives us the opportunity to plan your order as soon as your purchase order arrives, without having to receive the goods.

Our free-of-charge offer to ensure lightning-fast turnaround time and minimal downtime.

Ranges and Specifications for Standard Gas Flowmeter Calibrations:

We calibrate with air and real gases(*) on our Sonic Nozzle test stand, laminar flow element test stands or our bell provers.

Exact pressure and temperature compensation is carefully carried out and taken into account in the evaluation algorithms.

*- Practically any non-hazardous gas can be used for calibration including Helium, Argon, Nitrogen, Methane, Propane, etc.  There are flow range limitations due to practical reasons,  so please contact our technical experts for details.

Volumetric Flow:

  • 0,1 ml/min to 20.000 Nl/min
  • Accuracy: +/- 0.26% … 0,.35% of reading


Mass Flow:

  • 1,3 mg/min to 2400 kg/min
  • Accuracy: 0,24% … 0,35% of reading


The exact flow ranges and their corresponding uncertainties  can be found in the DAkkS Certification Annex.
