What is a anemometer calibration log template?
An anemometer calibration log is a formal record used to document the periodic calibration of a cup, vane, hot-wire or ultrasonic anemometer against a traceable wind-tunnel reference. The log captures the instrument identity, the wind tunnel or laminar flow reference used, the anemometer sensor type, the rated velocity range and the as-found and as-left readings at each calibration point across the working envelope. Standard practice covers a zero offset check at still air, low-velocity calibration at 0.1 to 2 metres per second for occupational hygiene and HVAC face velocity duty, mid-range calibration at 2 to 10 metres per second for general ventilation and weather monitoring, and high-velocity calibration at 10 to 30 metres per second for mine ventilation, weather station and wind farm duty. Direction calibration and span linearity round out the procedure for vane and ultrasonic instruments where azimuth response matters.
From a regulatory angle, anemometer calibration sits inside a framework that occupational hygienists, HVAC commissioning engineers and ventilation engineers rely on for defensible measurement. AS ISO/IEC 17025 sets the international competence standard for the calibration laboratory or in-house procedure that issues the certificate, with traceability through the National Measurement Institute. AS HB 9 covers occupational hygiene measurement practice in Australia, which prescribes the use of calibrated anemometers for personal sampling, LEV face velocity surveys and indoor air quality assessment. Australian Industrial Hygiene Association guidelines reinforce the calibration interval for hygiene instruments, and ASHRAE 111 covers HVAC system testing and balancing measurement, including anemometer accuracy class. In mine ventilation, state mining safety regulators and the relevant MDG guidelines require anemometer readings used for primary airflow surveys to be backed by a current calibration certificate. A documented calibration log is the artefact auditors, hygienists and mines inspectors will look for first when they question the integrity of a velocity reading.

Benefits of using this anemometer calibration log template
- Hygiene measurement assurance: documented calibration confirms anemometer readings are accurate before they are used for personal sampling, LEV face velocity surveys or indoor air quality
- HVAC commissioning evidence: ASHRAE 111 and the testing and balancing chain require anemometers to be calibrated against a wind tunnel reference before design verification
- Mine ventilation compliance: state mining safety regulators require anemometer readings on primary airflow surveys to be backed by a current NMI-traceable calibration certificate
- Detect sensor drift early: trended as-found readings across low, mid and high velocity reveal gradual drift before the anemometer falls outside its accuracy class
- Direction response verification: rotating the anemometer through 360 degrees in the wind tunnel flags vane stiction, bearing wear and ultrasonic transducer drift
- Identify damaged instruments: repeated zero offset, span failures or low-velocity errors flag anemometers dropped, exposed to dust, oil mist or moisture, or stored contaminated
- Sensor-type discipline: separate calibration records for cup, vane, hot-wire and ultrasonic instruments force the right calibration to be applied to the right sensor type
- Due diligence record: in the event of a hygiene investigation or mine ventilation incident, a stamped log demonstrates the anemometer was verified at survey time

What to include in a anemometer calibration log template
This anemometer calibration log template covers 11 key areas:
- Instrument details: make, model, serial number, asset/ID number, sensor type (cup, vane, hot-wire or ultrasonic), rated velocity range, accuracy class and probe length
- Reference standard details: wind tunnel or laminar flow reference make, model, serial number and NMI-traceable certificate number, four times better than the anemometer accuracy class
- Environmental conditions: ambient temperature, relative humidity, barometric pressure and reference stabilisation time recorded against the calibration event for air-density correction
- Zero offset check: as-found still-air reading recorded with the anemometer protected from any draught, with the indicator returning to zero after airflow is released
- Low-velocity calibration: as-found and as-left readings at 0.1, 0.5, 1.0 and 2.0 metres per second for hygiene and HVAC face velocity duty, with deviation calculated
- Mid-range calibration: as-found and as-left readings at 4, 6, 8 and 10 metres per second for general ventilation and weather monitoring duty, with deviation calculated
- High-velocity calibration: as-found and as-left readings at 15, 20, 25 and 30 metres per second for mine ventilation, weather station and wind farm duty
- Direction calibration: for vane and ultrasonic anemometers, as-found and as-left azimuth readings at 0, 90, 180 and 270 degrees against the wind tunnel reference direction
- Span linearity: regression of the as-found readings against the reference values across the working envelope to flag non-linear sensor response on a single sweep
- Sensor-type sign-off: confirmation that the calibration procedure matches the sensor type, with a note where the anemometer has been moved between application categories
- Technician identity and sign-off: occupational hygienist, HVAC technician or ventilation engineer name, qualification number, calibration date and signature confirming the anemometer is fit for service
How to use this anemometer calibration log template
- 1. Record the instrument details: fill in make, model, serial number, sensor type, rated velocity range and accuracy class at the top of page 1, cross-reference against the hygiene or commissioning instrument register to confirm the anemometer identity before any test airflow is applied
- 2. Record the reference standard: capture make, model, serial number and NMI-traceable certificate number of the wind tunnel or laminar flow reference, confirm the reference accuracy is at least four times better than the anemometer accuracy class and that the reference certificate is current
- 3. Stabilise the anemometer: allow the anemometer to sit at the calibration room ambient temperature for at least 30 minutes before testing, log the ambient temperature, relative humidity and barometric pressure, and verify the sensor head is clean and free of dust, oil mist or moisture
- 4. Run the zero offset check: with the anemometer protected from any draught in the still-air chamber, record the as-found indicator reading, confirm the zero offset is within the accuracy class and adjust the zero if the instrument allows it
- 5. Run the low-velocity sweep: position the anemometer in the wind tunnel at 0.1, 0.5, 1.0 and 2.0 metres per second in turn, record the as-found indicator reading at each test point and calculate deviation against the accuracy class for pass or fail
- 6. Run the mid-range sweep: increase the wind tunnel velocity to 4, 6, 8 and 10 metres per second in turn, record the as-found indicator reading at each test point and calculate deviation against the accuracy class
- 7. Run the high-velocity sweep: increase the wind tunnel velocity to 15, 20, 25 and 30 metres per second in turn, record the as-found indicator reading at each test point and calculate deviation against the accuracy class for mine ventilation, weather station or wind farm duty
- 8. Run the direction calibration: for vane and ultrasonic anemometers, rotate the instrument through 0, 90, 180 and 270 degrees in the wind tunnel reference flow, record the as-found azimuth reading at each direction and flag vane stiction or transducer drift
- 9. Close the record: stamp the calibration sheet with the technician name and qualification number, set the next calibration due date based on the application interval, attach a calibration sticker to the anemometer body and load the certificate against the asset in MapTrack

Anemometer calibration intervals are driven by the application category, the sensor type and the accuracy class required. For occupational hygiene face velocity surveys and indoor air quality assessment under AS HB 9, the typical interval is 12 months from the previous calibration sticker, with hot-wire instruments often calibrated every 6 months because the heated sensor is sensitive to dust and oil mist contamination. For HVAC commissioning and testing and balancing work under ASHRAE 111, the interval is also 12 months. For mine ventilation surveys feeding into the primary airflow circuit, state mining safety regulators typically require 12 months but tighten the interval to 6 months for cup and vane instruments exposed to dust-heavy environments. Outside the scheduled cadence, an anemometer must also be calibrated immediately after a suspected impact event, exposure to oil mist or moisture, extended storage, or any change in sensor type or probe length that affects the wind-tunnel response.
