   • Gravimetric Method: This method measures the mass of air flowing through a system over a specific time. It is highly accurate but can be time-consuming and require specialized equipment.
   • Volumetric Method: This method measures the volume of air flowing through a system over a specific time. It can be implemented using various techniques, such as:
     • Bell Prover: A bell prover is a device with a movable bell that traps a known volume of air. The airflow rate is determined by measuring the time it takes for the bell to move a specific distance.
     • Laminar Flow Element (LFE): An LFE is a device with a series of parallel channels that create laminar flow. The airflow rate is determined by measuring the pressure drop across the LFE.

2. Secondary Calibration Methods: These methods involve comparing the readings of the instrument being calibrated to a calibrated reference instrument. They are generally more convenient and less expensive than primary methods.
