PTG-M100 in the flow time measurement configuration (on the left / on top) and PTG-M100 with the optional manual stirrer and the digital height gauge for angle of repose measurement (on the right / at bottom)

The instrument consists of a solid base plate with a stand and a conical funnel, which can be equipped with different pouring nozzles. The optional PTG-M manual stirrer may be used for powders which do not flow well. The height of the stirrer and funnel can be adjusted freely up and down and locked into place without a risk of twisting and without using any tools. The instrument includes a powder collecting tray, which can be easily removed for cleaning. The base plate with integrated spirit level can be adjusted via three points to ensure a level installation.

To start the test insert the powder into the funnel and open it by using a slider. To measure the angle of repose, the product flows through the funnel and is collected on a 100mm diameter dish forming a cone. Once the powder flow stops, use the supplied digital height gauge to measure the height of the cone at its tip. Since the surface of the collecting dish is completely filled, the cone angle can easily be calculated.

To measure the flowability, a stopwatch and a laboratory balance are used to check the time it takes for 100g of sample to flow through the funnel and to be collected inside a plastic beaker. Changing between these modes of operation is easy and does not require the use of any tools.
