Features and Benefits:
- Precision Nozzle. The precision nozzle incorporated in the ACCU-flo reduces the measurement area by 50%. The nozzle also boosts the measured differential pressure by a factor of 4, ensuring high accuracy flow measurement of ±0.5% of actual flow down to 200 FPM duct velocity.
- Airflow Processing. To achieve its precise measurement accuracy under adverse conditions caused by turbulent, rotating, and multi-directional airflows, the ACCU-flo uses a parallel cell honeycomb panel to process the flow into velocity vectors parallel with its longitudinal axis. Downstream of the cell the precision nozzle compresses the straightened airflow, which has the effect of flattening the velocity profile where it encounters the total and static pressure sensing manifolds. The combination of the honeycomb panel and precision nozzle eliminates the traditional need for long upstream straight runs of duct required to obtain accurate flow measurement.
- Equal Weighted Average. Within the separate total and static pressure manifolds the individually sensed pressures are pneumatically averaged in a manner that gives equal weight to each value. The equal weighted averaging compensates for any remaining minor variances in total pressure at the plane of measurement.
- Fechheimer Pitot Flow Measurement. Precision engineered placement of the Fechheimer static pressure sensors ensure accurate static pressure measurements in nonuniform airflow with angularity up to ±30 degrees.
