2. Calibration Methods
Different types of air meters require specific calibration methods. The two primary types of air meters discussed here are concrete air meters and air quality meters.
Concrete Air Meters
Use the inside and outside calibration tubes to calibrate the air meter. The curved outside calibration tube is screwed into the petcock, and the needle valve lever is pressed to open the petcock, filling the calibration vessel to the top. When the ship is full, open the opposite petcock to allow water to flow back into the base, ensuring 5% air in the base for proper gauge calibration.
Fill the meter’s chamber with water and apply pressure using the pump. Adjust the gauge to read the correct air content based on the known standard. This method verifies the meter’s ability to measure the pressure changes accurately.
Air Quality Meters
Use certified gas cylinders with known concentrations of specific pollutants. Connect the gas cylinder to the meter’s inlet and allow the gas to flow through the meter. Adapt the meter to match the gas’s known concentration.
Perform a zero calibration by exposing the meter to a clean air source and modifying the reading to zero. Then, perform a span calibration by introducing a gas with a known concentration and adjusting the meter to match the standard.
3. Verification
After meter calibration, the final step involves adjusting and verifying the air meter’s accuracy and reliability.
Adapt the meter’s settings based on the air meter calibration results. This may involve tightening or loosening screws, adjusting dials, or modifying software settings to align the meter’s readings with the known standards.
Ensure the meter’s readings remain stable over time. Consistent readings indicate that the meter is properly calibrated.
Verification
- Repeated Measurements: Perform multiple measurements using the calibrated meter to verify accuracy. Compare the results with the known standards to ensure consistency.
- Cross-Verification: Use a secondary, independently calibrated meter to cross-verify the readings. This step provides an additional layer of assurance that the meter is accurate.
- Documentation: Record the calibration process, including the equipment used, calibration standards, adjustments made, and final readings. Maintain these records for future reference and compliance with industry regulations.
