Overview

Our Granulate flow tester series

Three Devices, all options

The devices of the ERWEKA granulate flow tester family were developed to determine the flow behavior of powders and granules using various measurement methods.

As an entry-level device, the GTL is ideally suited for the USP/EP-compliant measurement of the flowability of powder and granules according to the measurement methods of weight and volume. Thanks to the simple numerical membrane keypad and the LC display, the device is easy to operate and all results can also be printed out.

The GT has a scale - this allows the stable weight to be measured during the flow process. In addition to the two measurement methods of the GTL (flowability by weight and volume), the GT can also measure the flowability over a specified time as well as the flow angle with graphic display.

The GTB complements the extensive capabilities of the GT with an advanced, automatic laser measurement of the angle of repose - this gives the user a comprehensive picture of the flow properties of the evaluated powder or granulate.

Both devices, the GT and the GTB have an LC display and a membrane keypad for easy operation, which also enables the results to be printed out. Various accessories also make it possible to carry out customer-specific measurements that are not EP-compliant. For example, outlet nozzles with different diameters or smaller receiving funnels can be selected. The GT and GTB can optionally be equipped with a stirring unit for samples with poor flowability. The speed can be regulated in four stages.

The GT Series at a glance

Our three devices offer several different measuring methods.

  • GTL

    ERWEKA GTL

    The entry-level devices

    The entry-level GTL enables the measurement of the flow time of a predefined amount of granulate or powder (according to EP) as well as the measurement of the flow time of a given sample volume. Thanks to the simple numerical membrane keypad, operation is extremely easy. Test results can be shown on the LC display and printed out with a connected printer.

    In the standard version, the GTL is supplied 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.
  • GT

    ERWEKA GT

    The mid-tier

    The ERWEKA GT granulate flow tester has a special, integrated scale that can measure the weight of samples while testing their flow behavior. Users can measure the flow time of a sample weight, a given sample volume or the flow time of a weight in a given time.

    With the large full-graphic LC display and the membrane keybpad, the device can be operated comfortably. For an easy comparison, a graph is calculated, displayed and / or printed (quantity / time).

    • Flowability measurement by weight. (EP method)
    • Flowability measurement by volume.
    • Flowability measurement over a specified time.
    • Determination of the flow angle with graphic representation on the printout.
  • GTB

    ERWEKA GTB

    The allrounder

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

    For this purpose, the Pfrengle method is applied and a powder or granule cone is heaped up. The geometry of the cone is optically measured using a laser (class 2) and the angle of repose the sample is displayed as a result. The stirring unit with four speed levels is standard on the GTB.

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