| Abstract: | The paper introduces a method of mass flowrate measurement based on polarized charge, which is a kind of new electrostatic method. Polarized charges generate on the particles when they pass electric field, and the quantity of charge has the direct relationship with mass flowrate of pulverized material in pneumatic pipeline. The method has no disturbance on the state of the flow, and this kind of flowmeter is simple and durable and can get output of mass flowrate directly. The method is especially suitable for the process of industrial control. |
