New Solution for Flow Monitoring
New Solution for Flow Monitoring
The latest released AFMP Average Flow Measuring Tube by eyc-tech is a state-of-the-art instrument designed to meet the rigorous requirements of industrial flow measurement. This measuring tube, which can be paired with a differential pressure transmitter, is versatile in a range of flow measurement applications. Integrating eyc-tech's innovative technology and multifunctional application advantages, the AFMP not only enhances measurement precision but also improves device stability and durability.
Core Technology
The AFMP Average Flow Measuring Tube is based on fluid dynamics principles, precisely calculating gas velocity by measuring static and total pressure differences. In large-diameter ducts, airflow velocity often varies between the center and near-wall areas, making single-point measurements insufficient for capturing the overall flow precisely. The AFMP utilizes a multi-hole Pitot tube design to average multiple airflow points, ensuring more precise and representative data. Additionally, this differential pressure-based flow meter is minimally impacted by airborne dust, making it ideal for use in dust-laden environments.
Product Features
- Pitot tube : Measure differential pressure caused by flow, combined with differential pressure sensor to calculate flow.
- Multi-Hole Structure : Averages differential pressure readings from multiple points for stable and reliable measurements.
- High-Sensitivity : Low pressure drop within the tube enables measurement of small value, with sensitivity down to 1 Pa.
- Durable Material : Made of SS316, providing strong corrosion resistance and long-term stability across diverse environments.
- Environment Resistant : Ideal for extreme conditions. Options for operating temperature up to 600C and pressure up to 10 bar.
- Dust-Resistant : Features a dust-resistant structure that resists clogging, ensuring stable flow measurement.
Applications
-
Low Air Flow: Equipped with eyc-tech’s PMM330 differential pressure transmitter using hot-wire differential pressure sensing technology, this setup offers high sensitivity and low zero drift, enabling precise measurement even under minimal differential pressures as low as 1 Pa. With its square-root extraction feature, the transmitter converts differential pressure to air velocity, measuring as low as 1 m/s, providing a high-precision solution for airflow and air velocity measurement. This combination is particularly suitable for precise monitoring of low air velocities in HVAC systems and cleanrooms, ensuring optimal environmental control.
