摘要
针对传统的差压流量计其安装位置对直管段长度要求较长,精确度随时间延长明显下降和维修工作量大等问题,阐述了威孔流量计的工作原理、结构和性能特征。其安装位置对直管段长度要求短、压损低、精确度高、维修量少,性能稳定,并介绍了应用情况。
For the problems in conventional differential pressure flow meters,for example,its installation location requires a long straight pipe section,the accuracy drops significantly with time,and large amount of maintenance work is involved,the working principle,construction and performance characteristics of V-cone flow meter are described.Its installation location involves shorter straight pipe section,low pressure loss,high accuracy,small amount of maintenance and stable performance.The application status is also introduced.
