100% EP-compliant measurement methods possible

Angle of repose laser measurement

Powder and granulate flow measurement with up to 5 methods

Three Devices, Multiple Measuring Methods

The Entry-Level Device

The GTL entry-level model enables the measurement of the flow time of a predefined quantity of granulate or powder (according to EP), as well as the flow time of a specific sample volume. Thanks to the simple numerical membrane keypad, operating the device is extremely easy. The test results can be shown on the LC display and printed out via a connected printer.

The standard version of the GTL is equipped with a stainless steel funnel (480 ml) and three stainless steel outlet nozzles (10/15/25 mm), which can be replaced by a quick coupling. Additional stainless steel funnels (100/200 ml) and outlet nozzles (6 / 8 / 11.3 mm) are optionally available.

  • Flowability measurement by weight (EP method)
  • Flowability measurement by volume

The Allrounder

The GTB is the fully equipped all-rounder of the GT family. In addition to the standard measurement of flow properties, it features a method for fully automatic determination of the angle of repose.

For this purpose, the Pfrengle method is applied and a powder or granulate cone is heaped up. The geometry of the cone is optically measured with a class 2 laser and the angle of repose of the sample is displayed as a result. The stirring unit with four speed levels is part of the GTB's standard equipment.

The device is conveniently controlled via a large LC full graphic display and a membrane keypad. Two certified cones (30° and 40°) can be purchased for the angle of repose measurement. The 45° cone is included as standard.

  • Flowability measurement by weight (EP method)
  • Measurement of flowability by volume
  • Flowability measurement over a certain time
  • Determination of the flow angle with graphical representation on the printout
  • Measurement of the angle of repose with a laser measuring device
