Product catalog summary
Overview
The HFlow 1 is a device designed to measure both bulk density and flow rate in pharmaceutical and metal powders. It offers three standard funnels—Hall, Carney, and Gustavsson—each compliant with USP, Ph. Eur., ASTM, and ISO standards, allowing for versatile application across different measurement requirements.
Specifications
  • Funnel Types: Hall, Carney, Gustavsson
  • Orifice Diameters: Hall (5 ± 0.2 mm), Carney (2.5 ± 0.4 mm), Gustavsson (2.5 ± 0.03 mm)
  • Funnel Angles: Hall (60° ± 0.2), Carney (60° ± 0.2), Gustavsson (30° ± 0.5)
  • Volume of Cups: 25 ± 0.05 ml
Measurement Procedures
Flow Rate Measurement:
  1. Weigh a 50 g sample.
  2. Add the sample to the funnel.
  3. Start timing when the powder begins to exit the orifice.
  4. Record the elapsed time when the last of the powder exits the orifice.
Bulk Density Measurement:
  1. Empty and weigh the cup.
  2. Add the sample.
  3. Adjust the height and scrape the excess.
  4. Weigh the filled cup to calculate bulk density using the formula ρΒ = M/VΒ, where M is mass in grams and VΒ is bulk volume in cm³.
Compliance
  • Flow Rate: USP <1174>, Ph. Eur. <2.9.36>, ISO <4490>, ASTM , ASTM , ISO <13517>
  • Bulk Density: ISO <4490>, ASTM , ISO <3923-1>, ASTM , ISO <13517>
Interoperability
The HFlow 1 can be combined with the Bettersizer 2600 laser diffraction analyzer to balance particle size distribution and flow properties of additive manufacturing (AM) powders.
Application Example
In feedstock preparation, undersized particles may aggregate, affecting powder bed fusion processes by increasing interparticle friction, which impedes flow behavior.

Application Example Analyzing bulk density and flow rate of various metal powders applied in additive manufacturing (AM). Ti alloy Stainless steel 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 Ti alloy Stainless steel Interoperability 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...
