Air Velocity Transducers

Air velocity transducers extend visibility beyond spot checks, delivering continuous data streams that help facilities maintain ventilation strategies in critical spaces. By tying velocity signals to building automation systems, agencies can track performance, enable alarms, and adjust control sequences based on actual conditions.

Applications

• Evidence Storage and Drying: Monitor airflow to support target exchange rates and odor control strategies.
• Forensic and Chemistry Labs: Trend hood and room velocities to support operating procedures.
• Firing Ranges: Track directional airflow and supply levels to support design intent.
• Isolation and Containment: Measure velocity near portals and in exhaust branches to support pressure zoning.
• Duct Monitoring: Verify minimum outdoor air flow and branch distribution for occupied areas.

Technical Considerations

• Output Types: Select analog (e.g., 0–10 V, 4–20 mA) or digital outputs compatible with your BAS/PLC.
• Range and Resolution: Match ranges to expected velocities; choose higher resolution for low-flow areas.
• Environmental Ratings: Confirm temperature, humidity, and particulate suitability for the application.
• Maintenance: Consider sensor access for cleaning and calibration in dusty or high-use environments.

Benefits

• Real-Time Insight: Continuous data helps teams identify drift, filter loading effects, or control issues.
• Trend Analytics: Historical velocity profiles support optimization, seasonal tuning, and incident reviews.
• Alarm Integration: Set thresholds that trigger notifications when conditions deviate from targets.
• Operational Efficiency: Reduce manual rounds and focus resources on priority tasks.

Deployment Best Practices

• Strategic Placement: Position sensors in locations with developed flow profiles to improve stability.
• Redundancy Where Needed: Use multiple points for critical branches or when flow is highly variable.
• Commissioning: Validate readings with a calibrated handheld meter and document baseline values.
• Data Governance: Label points clearly, apply engineering units, and back up BAS configurations.

Continuous velocity monitoring helps agencies move from reactive fixes to proactive management. The result is better insight, faster response to changes, and stronger support for policy-driven ventilation targets across high-stakes environments.
