Features
● Precision measurement : Adopting the unique fluid dynamics principles of Venturi tube, the FDM08 provides accurate measurement.
● Wide range of applications : Suitable for general gases, steam, contaminated gases, or high-humidity gases.
● Stable performance : No moving or electronic parts inside the pipeline, ensuring excellent long-term stability.
● Easy installation : Shorter front and rear straight pipe sections compared to standard throttling devices, approximately 2.5D in the front and 2D in the rear.
● Low pressure loss : Designed to minimize pressure loss, reducing energy consumption.Applications
Compressed air systems / Boiler systems / Industrial process gases / Water treatment aeration systems
