Airflow Instruments Velocity Meters

Airflow Instruments Velocity Meters provide precise airspeed measurement for ducts, diffusers, fume hoods, and process areas. With hot-wire or vane sensors, these handheld meters capture low to high velocities and compute volume from entered area. Fast sensors, clear displays, and optional logging help TAB professionals diagnose airflow issues and validate system performance. Use them for balancing, commissioning, and routine maintenance across commercial buildings, labs, and specialized HVAC systems.

Air velocity is a foundational metric for HVAC performance, influencing airflow balance, comfort, and contaminant control. Airflow Instruments Velocity Meters combine sensitive sensors with practical workflows to help you capture reliable readings in ducts, at grilles, and in specialized environments.

Capabilities

Velocity Measurement: Hot-wire probes excel at low flows and tight spaces; vane sensors offer robust averaging for terminals and intakes.
Volume Computation: Enter duct or grille area to convert velocity into CFM for quick decision-making.
Data Capture: Logging and note features support clear audit trails in commissioning reports.

Use Cases

TAB and Commissioning: Validate design velocities and volumes at critical points in the system.
Troubleshooting: Identify low-flow conditions, imbalances, and localized restrictions.
Labs and Fume Hoods: Check face velocity and verify performance against process requirements.
Process and Industrial HVAC: Monitor makeup air and exhaust points for operational stability.

Best Practices

Probe Alignment: Align the sensor with the airflow vector for accurate readings.
Multipoint Averaging: Use standardized grids for ducts and large faces to obtain representative results.
Density Corrections: Apply temperature and barometric inputs when your standard requires density-adjusted flow.
Maintenance: Keep sensors clean and verify calibration status to support repeatability.

Choosing the Right Meter

Sensor Type: Match hot-wire or vane sensors to the flow regime you see most often.
Range and Resolution: Confirm the instrument covers both low-flow diagnostics and higher-flow terminals.
Workflow Tools: Look for data logging, Bluetooth connectivity, and export options if you deliver detailed reports.

With dependable sensors and straightforward operation, these velocity meters help you diagnose airflow issues efficiently and document performance with confidence.
