eyc-tech Small Value Precise Measurement: Equipment Upgraded, Technology Enhanced
In modern industry and scientific research, precisely measuring micro air velocity and airflow is critical for ensuring the performance of precision systems and the reliability of research data. With technological advancements, eyc-tech offers exclusive patented wind tunnel devices and air volume calibration systems (sonic nozzles), and has integrated Laser Doppler Anemometry (LDA) for precise calibration of air velocity, airflow, and differential pressure transmitters, providing you with exceptional solutions for low air velocity and airflow measurement.
Low Air Velocity 0.1 m/s |

eyc-tech’s exclusive patented wind tunnel devices undergo rigorous testing and calibration procedures according to IEC61298 and ISO17025 standards. The system was run 3-cycle or 5-cycle curve inspection by measuring circles quantities and positions of testing points to achieve calculation of the targets and calibration of the linear curve which help air velocity transmitter to maintain high precision quality. By combining the wind tunnel device with LDA, we could reduce the measurable minimum value to 0.1 m/s. This precision in low air velocity measurement is crucial for environmental monitoring, manufacturing process control, ventilation system optimization, and equipment safety. eyc-tech’s air velocity transmitters are calibrated using advanced wind tunnel devices and LDA during their design and manufacturing processes.

Micro Differential Pressure 1 Pa Measurement |
Differential pressure measurement is crucial for the precise calculation of air velocity and airflow. By combining wind tunnel devices with Laser Doppler Anemometry (LDA), we can not only measure air velocity precisely but also convert low air velocity into micro differential pressures using Bernoulli's principle from fluid dynamics. This verifies the measurement capabilities of eyc-tech's hot-wire differential pressure measurement technology, ensuring measurement reliability down to 1 Pa. The application of advanced micro differential pressure measurement technology allows various industries to easily monitor process and system conditions, mitigating risks associated with small value fluctuations and achieving higher efficiency and safety.
