The HFlow 1 flowmeter funnel is a reliable and accurate device to measure bulk density and flow rate in pharmaceutical and metal powders. It allows the sample to flow through a standard Hall funnel, Carney funnel, or Gustavsson funnel, providing precise and reliable measurements of powder flowability. Complied with USP, Ph. Eur., ASTM, and ISO standards, it is ideal for use in laboratories and production facilities working with pharmaceutical and metal powders.
Features and Benefits
- ● Measurement: Bulk density and Flow rate
- ● Technology: Flowmeter Funnel
- ● Three funnels: Hall (2.5 mm orifice), Carney (5 mm orifice), and Gustavsson (2.5 mm orifice).
1. Measurement: Bulk Density and Flow Rate
The HFlow 1 measures both bulk density and flow rate in pharmaceutical and metal powders, offering a choice of three standard funnels—Hall, Carney, and Gustavsson. Complied with USP, Ph. Eur., ASTM, and ISO standards, it accommodates diverse applications, allowing customers to choose the best fit for their measurement requirements.
2. Measurement Procedure
- Bulk Density
- Flow Rate
3. Application Example
Analyzing bulk density and flow rate of various metal powders applied in additive manufacturing (AM).
Hall, Carney, and Gustavsson funnels equipped in HFlow 1 have different orifice diameters and angles respectively. They can be employed to test the bulk density and flow rate of a wide range of metal AM powders for evaluating printability.
The combination of the laser diffraction analyzer Bettersizer 2600 and HFlow 1 assists in balancing the particle size distribution and flow property of AM powders.
In the feedstock preparation process, undersized particles tend to aggregate, which can be detrimental to powder bed fusion processes. The agglomerates will impede the flow behavior of the powder by increasing interparticle friction.
