Erweka - Model GT Series -Granulate Flow Tester

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 (according to Maly) as well as the flow angle alpha with graphic display (according to List and Müller).

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 for graphical representation of the flow angle 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 stirring unit is required for the Pfrengle measuring method.

The GT Series at a glance

Our three devices offer several different measuring methods.

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.
