BEVOGTE air flow calibration laboratory is well equipped to fulfil all the needs in a professional and prompt manner for volume and mass flowmeters, calibration standards and internal transfer standards. An air flow meter essentially measures the rate that the air or gas that moves through the instrument. The measurement of gas quantity and flow rate requires special care and techniques because gases are compressible and are affected by temperature, pressure and viscosity. With high engineering experience in gas flow metering applications, BEVOGTE can offer a first-class worldwide solution to service and calibration requirements on all leading types of flow meters.
