EBM PAPST INLET RING 400MM (LONG) - Part Number: 54476-2-4013
Enhance your airflow measurement setup with the EBM PAPST Inlet Ring 400MM (Long), designed for precise airflow analysis in backward-curved centrifugal fans. Manufactured in China, this inlet ring is suitable for various impeller sizes and fan types, ensuring accurate static pressure measurements essential for performance optimization.
Product Features:
Designed for airflow measurement using instrumented inlet rings
Compatible with backward-curved centrifugal fans
Available with a piezometer ring featuring four pressure taps for improved accuracy
Single pressure tap version also available
Pre-mounted pneumatic tube connector (4mm internal diameter) for easy setup
Empirically calibrated with a nozzle calibration factor (k-value)
The inlet ring utilizes Bernoulli and Continuity equations to calculate airflow based on static pressure drops across a converging nozzle. The airflow (Q) in CFM is determined by the formula:
Q = 9.36k • Δs / ΔP
where ΔP is the static pressure drop, and Δs is the standard air density ratio. The device can be configured with either a single pressure tap or multiple taps in a piezometer ring for more accurate measurements, especially in uneven pressure conditions.
Additional Information:
Connection to a differential pressure transducer (DPT) is via pneumatic tubing (4mm diameter)
Selection of a DPT with an appropriate range is critical for measurement accuracy
