为了测量粉状物料的流量,乌拉尔全苏热工研究所研制成一种装置。其工作原理是使粉粒物料事先带电,再测量其电流。这种方法可测量输送物料的流量而不使流束产生机械变形。 该流量计的方块图见图1,包括变换器Ⅰ和测量单元Ⅱ。变换器安装在粉状物料流经的管道1上,由静电室2和测量室3组成,它们彼此之间、以及与管道之间用绝缘隔离层4分开。静电室2由电源5供电而产
In order to measure the flow of powdery material, Ural Thermal Research Institute has developed a device. Its working principle is to make the powder material charged in advance, and then measure the current. This method measures the flow of material to be conveyed without mechanical deformation of the stream. The flowmeter block diagram shown in Figure 1, including the transducer Ⅰ and Ⅱ measurement unit. The converter is mounted on a pipe 1 through which powdered material flows, consisting of a static chamber 2 and a measuring chamber 3, separated from each other and from the pipe by an insulating barrier 4. The electrostatic room 2 is powered by the power source 5
