摘要
涡街流量计以其自身的一系列优点已经成为流量测量仪表家庭中不可缺少的一员,在计量检测中发挥着越来越大的作用。针对涡街流量计易受噪声干扰、现场测量精度不高、量程比有限等问题,采用数字信号处理的方法加以改进,并采用FPGA实现各处理模块。
Vortex flow meter become an indispensable member of the family of flow measure instrument because of it＇s a series of advantage already,playing a greater and greater role in measuring,Apt to some problems,such as vortex flow meter is subjected to noise disturb,the measuring accuracy in industrial fields is not high,the span ratio is lower than the theoretic value,this subject adopts digital signal processing methods to improve vortex flow meter,and adopts FPGA realize each processing unit.
