Hall flow meter / bulk density tester (funnel stainless steel material)
FL4-1流动性和松装密度测定仪（漏斗黄铜材质）fluidity and bulk density tester (funnel brass material)
一、满足标准Meet standard：GB 1482-2010-T GB1479-84、 GB1482-84
其检测方法与国际上通用的检测方法具有通用性。本产品也适用于类似粉末粉体流动性和松装密度之测量。
the test method and the international *mon test methods are universal. The model is also suitable for the measurement of fluidity and bulk density of powder like powder.
二、原理principle：
1.金属粉末的流动性，以50g金属粉末流过规定孔径的标准漏斗所需要的时间来表示。The flow of metal powders is expressed in terms of the time required for the 50g metal powder to flow through the standard funnel of the specified aperture.
2.松装密度的测定采用标准漏斗法Determination of bulk density use by standard funnel method.
