摘要
针对电磁流量计由于其自身原理特性,长期以来一直限制其在采矿和选矿等安全要求较高场所使用的现实,提出了一种采用新型单片机控制并满足矿用防爆和本质安全要求,实现测定污水和泥矿浆流量的电磁流量计电路的实现方法,通过设计、测试和分析,发现该电磁流量计在测量过程中,所得到的实测数据经最小二乘法进行直线拟合后,其误差可以控制在0.8%以内。表明这种电磁流量计已达到国内外同类产品的先进水平。
Due to its principle characteristics, electromagnetic flowmeters always has long been restricted in the use of safety requirements higher field, such as mining and beneficiation etc., It puts forward to use a new type MCU to control and meet mine explosion and the essential safety requirements,to achieve the implementation of electromagnetic flowmeter circuit for measuring of sewage and mud slurry flow. By design,testing and analysis, we found that during in the measurement process,the measured data obtained by the least squares linear fitting method,its error can be controlled less than 0.8%. It shows that the electromagnetic flowmeter has reached the advanced level of similar products at home and abroad.
