Mass Flow Controller Calibration
At our calibration facility we carry out calibrations of Mass Flow Controllers (MFCs) in the range of 5,0 Sml / min - 50,0 Sl/min. The calibrations can be carried out with the following anhydrous gases: air and nitrogen. The flow rates indicated are expressed in reference to temperature and pressure standard conditions: 0 °C and 101325 Pa.
The Mass Flow Controller (MFC) calibration takes place in our laboratory under controlled temperature and humidity conditions in the following ranges:
- Calibration facility temperature: 23 °C ± 1 °C
- Humidity: 30 / 70 %
The Mass Flow Controller (MFC) is calibrated by comparing the sample flow measurement with our primary standard flow rate, according to the calibration method defined in the calibration procedures stored at our calibration laboratory.
We perform the calibration of the Mass Flow Controller (MFC) from 3 to 10 calibration points between 5/10% and 100% of the measuring range of the device under test (DUT) with a minimum of 3 repetitions of the calibration test and up to 5 repetitions of the calibration test.
As result of the preformed test, a calibration report will be issued containing:
- Sample rate at standard reference conditions of 0 °C and 101325 Pa
- Flow rate measured and controlled by the Mass Flow Controller under standard conditions of 0 °C and 101325 Pa
- Calibration coefficients and average calibration coefficient for calibration tests performed
- Calibration uncertainty expressed as extended uncertainty of the calibration coefficients resulting from the tests performed
- Environmental conditions during the calibration process
- Reference to the procedures and the metrological chain used in the calibration process.
