下图为使用微处理机的物料流量测量及控制系统。其中采用了广泛使用的冲击式在线流量计主要应用于炭粉、化工产品以及食品等各种粉粒状物料在生产过程中的高精度流量测量及控制。 冲击式在线流量计所测得的供料机B出口物料瞬间流量值经由指示前置放大器转换成模拟电信号。此信号经由比例器再乘以由微处理机系统所确定的系数后,送到调节器。 The picture below shows the material flow measurement and control system using a microprocessor. Which uses a widely used impact on-line flowmeter is mainly used in carbon powder, chemical products and food and other powdery materials in the production process of high-precision flow measurement and control. Impact on-line flowmeter measured the instantaneous value of the material flow at outlet B of the feeder is converted to an analog electrical signal by indicating the preamplifier. This signal is multiplied by the ratio determined by the microprocessor system to the regulator.
