Continuous flow measurement at low solid/air ratios PicoFlow SWR Engineering

Mã sản phẩm: PicoFlow |
Thương hiệu: SWR Engineering

Giá bán: Liên hệ

PicoFlow was specially developed for measuring powder flows in transport lines with very low material concentrations.
PicoFlow is particularly good in pneumatic applications but will also work reliably in free-fall applications with drop speeds of at least 2 m/s.

The measuring system delivers absolute measurements (after calibration) in g/h or kg/h.

A special air purging system is also available as an option. This is used for materials which tend to bake onto surfaces.

Thông tin sản phẩm

Measuring powder flows in transport lines with very low material concentrations.

In pneumatic applications for material flow rates of up to 100 kg/h (depending on application)

In free-fall with a drop speed of at least 2 m/s (approx. 25 cm drop height)

In cases where dust measuring instruments cannot cope and flow rate measuring instruments are overspecified
