Hall Flowmeter/Hall Flow Meter

霍尔流速计用于确定金属粉的流动l速度。其使用前须经标定。
Hallflowmeter/Flow Meter works according to international standard ISO 4490 Metallic powders - Determination of flow rate by means of a calibrated funnel (Hall Flowmeter). This international standard specifies a method for determining the flow rate of metallic powders, including powders for hardmetals, by means of a calibrated funnel (Hall flowmeter/Flow Meter). The method is applicable only to powders which flow freely through the specified test orifice.
