FlowFinder+: The Next Evolution in Powered Flow Hoods
The FlowFinder+ is a state-of-the-art powered flow hood designed for precision in all air measurement applications. Unlike traditional flow hoods that struggle with accuracy in low-pressure conditions, the FlowFinder+ achieves an unmatched zeroing precision of 1/100 Pa, ensuring minimal disruption to system characteristics.
Its advanced onboard fan technology effectively eliminates supply-direction jet interference, delivering highly accurate flow measurements using a combination of RPM monitoring and stabilized pressure readings. Whether measuring return, exhaust, or supply flows, the FlowFinder+ maintains exceptional accuracy of ±3%, outperforming passive flow hoods that often register errors between 20% and 50%—a performance validated by LBL’s extensive research.
Unrivaled Performance & Versatility
- Wide Measurement Range: 6 to 326 CFM in full zero-balance mode, expandable to 550 CFM in compensated mode.
- Compact & Lightweight: Ideal for kitchen exhaust, HRV flows, and confined spaces.
- Perfect for Duct Leakage Testing: When paired with a Blower Door, the FlowFinder+ becomes a powerful diagnostic tool. Pressurizing a home to 25 Pa allows operators to visually and quantitatively assess duct leakage, identifying cost-effective energy improvements.
Breakthrough Enhancements
- Faster Operation: 50 Hz sampling rate for near-instantaneous data acquisition and response.
- Unmatched Stability: Upgraded hardware and control software ensure seamless and error-free operation.
- WiFi-Enabled Upgrades: Enjoy wireless firmware updates, keeping your device future-ready.
- Improved Battery Efficiency: Faster, more stable readings reduce measurement time, extending battery life.
- Secure Upgrades: Dual bootloaders ensure reliable firmware updates with minimal risk.
The FlowFinder+ redefines accuracy, speed, and usability in airflow measurement, making it the ultimate tool for HVAC professionals and energy auditors.
