Messung und Prüfung


Meier (MTI) developed its first airflow measurement machine in 1979 and has tested millions of gas turbine engine components since then.
Each machine is designed, built and, tested to comply with international standards for Laboratory Equipment Safety, EN61010-1 and Laboratory Equipment Electromagnetic Compatibility, E61326-1.
Reference flow standards maintained by the Flow Measurement Center (FMC) have been calibrated directly by the National Institute of Standards and Technology (NIST), in conjunction with accredited flow labs. Uncertainty in reference flow standards is ±0.06% to ±0.20%, k=2.
FMC is ISO 17025 accredited to provide proficient airflow measurements, effective flow area (EFA) and calibrations. MTI is NADCAP approved for airflow measurements. MTI is approved for airflow by many gas turbine engine manufacturers.
FMC has successfully performed multiple intra-proficiency airflow tests directly with NIST.
EFA testing per customer requirements and correlated as needed. Fleming rig tooling compatible.

MTI airflow measurement machines have several benefits:

Available for purchase or lease.
On-site support for training and service.
Regular updates from MTI Continuous Improvement Department.
Machines and systems create value by reducing the cost of ownership without sacrificing performance.
Promote continual improvement using built-in statistical process controls and enterprise-wide access to test data.
Deliver a standard work environment in a small footprint and a user-friendly turnkey system.

MTI airflow measurement machines are accurate:

Accuracy assured by using a combination of sonic nozzles, state-of-the-art measurement devices and time-proven proprietary software.
Accurate measurements are traceable to the International System of Units (SI) through an unbroken chain of comparisons to a National Metrology Institute, such as the NIST, which are signatories to the International Committee for Weights and Measures Mutual Recognition Arrangement, or directly by the International Bureau of Weights and Measures.
Uncertainty in reported flow rates is ±0.29% to ±0.40%, k=2. Up-to-date measurement uncertainties are listed on FMC’s accredited scope, which can be found on A2LA’s website.
Capable of flow rates of 0.00006 to 1.5 lbm/s. EFA from 0.10 to 40 square inches, 1 to 10 inches of water inlet pressure.
