The ERWEKA GT has been designed to determine flow properties of powders and granules according to four different measuring methods:
ERWEKA的颗粒流动测试仪是根据四中不同的测试方法来测定粉末和颗粒的流动性特征
 
• determination of flow time of the pre-defined sample weight (according to EP)
测定预先确定过样品重量的样品流动时间（根据EP）
 
• determination of flow time of the pre-defined sample volume
测定预先确定过样品体积的样品流动时间
 
• determination of weight of the sample which flows within a pre-defined time
测定预先确定流动时间内的样品重量
 
• ratio of flow time and sample weight presented in the form of graphical curve with a subsequent calculation of the cotangents of the flow angle a = arctan (weight/time)
流动时间和样品中的比值将以图形曲线的形式表现出来，   然后再计算气流角的余切，a是反正切（重量/时间）
 
Where samples exhibit poor flowability, the hopper is available with a stirring device with variable speed control.
当样品表现出较差的流动性，料斗上的可变控速搅拌装置可以调节。
