FT-102霍爾流速計(jì)/松裝密度測(cè)定儀（漏斗不銹鋼材質(zhì)） Hall flow meter / bulk density er (funnel stainless steel material) FL4-1流動(dòng)性和松裝密度測(cè)定儀（漏斗黃銅材質(zhì)）fluidity and bulk density er (funnel brass material) 一、滿足標(biāo)準(zhǔn)Meet standard：GB 1482-2010-T GB1479-84、 GB1482-84 其檢測(cè)方法與國(guó)際上通用的檢測(cè)方法具有通用性。本產(chǎn)品也適用于類似粉末粉體流動(dòng)性和松裝密度之測(cè)量。 the method and the international common 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.金屬粉末的流動(dòng)性，以50g金屬粉末流過(guò)規(guī)定孔徑的標(biāo)準(zhǔn)漏斗所需要的時(shí)間來(lái)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.松裝密度的測(cè)定采用標(biāo)準(zhǔn)漏斗法Determination of bulk density use by standard funnel method. 三、技術(shù)規(guī)格technical specifications 漏斗下徑：φ2.5㎜和φ5.0㎜ funnel bottom diameter：φ2.5㎜ and φ5.0㎜ 角度：60度 angle:60 degree 容 量： 25 ml volume: 25 ml 配置：秒表Stopwatch，鋼尺、毛刷、水準(zhǔn)儀，收集盤
