Abstract: A system with a principal hopper having balances and discharge piping fitted with a valve and a flow sensor. The lower end of the piping extends into a secondary hopper which is connected to a pipe fitting powder to an ingot mold. The powder flows from the principal hopper into the secondary hopper and flows through the pipe into the ingot mould where it spreads over a cast metal surface. When the level of powder in the secondary hopper reaches the lower end of the piping, the flow is terminated and the flow sensor initiates valve closure. The valve is reopened after a specified time period or when another sensor indicates the absence of powder. In this way, it is possible to determine powder consumption by measuring the time between two successive valve openings or closures.

Abstract translation: 具有主料斗的系统具有平衡和排出管道，其配有阀和流量传感器。 管道的下端延伸到二次料斗中，二次料斗将管配件粉末连接到铸锭模具。 粉末从主料斗流入二次料斗，并通过管子流入铸锭模具，在铸模上铺展在铸造金属表面。 当二次料斗中的粉末水平达到管道的下端时，流动终止，流量传感器启动阀门关闭。 阀在特定时间段之后重新打开，或者当另一个传感器指示不存在粉末时重新打开。 以这种方式，可以通过测量两个连续的阀开口或闭合件之间的时间来确定粉末消耗。
