• Primary Calibration Methods: These methods rely on fundamental physical principles and are traceable to national or international standards. They are typically used to calibrate reference standards and are considered the most accurate.
  • Volumetric Method: This method involves measuring the volume of air flowing through a device over a known period. It is typically used for calibrating flow meters and other volumetric flow measurement devices.
  • Gravimetric Method: This method involves measuring the mass of air flowing through a device over a known period. It is typically used for calibrating mass flow meters.
• Secondary Calibration Methods: These methods compare the readings of the instrument being calibrated against a calibrated reference standard. They are generally less accurate than primary methods but are often more practical for routine calibration.
  • Transfer Standard Method: This method involves using a calibrated transfer standard to compare the readings of the instrument being calibrated. The transfer standard is typically a high-accuracy flow meter that has been calibrated using a primary method.
  • Wind Tunnel Method: This method involves placing the instrument being calibrated in a wind tunnel and comparing its readings to the known air flow rate in the tunnel.
  • Field Calibration: This method involves calibrating the instrument in its operating environment. It is often used for large or fixed instruments that are difficult to remove for calibration.
