摘要
校准脉冲输出型流量计仪表系数的传统方法有容积法及称重法等。这里介绍的是以数控伺服电机驱动计量缸产生标准流量、以两次中断法启停流量计脉冲计数 ,从而获取仪表系数的准确估计值。
The traditional methods calibrating meter\|factor of flowmeters with pulse output are volume measure,weight measure and so on.A new method is introduced as follow:the standard flow is made by a cylinder drived by a servo motor,count stops or starts through twice PC interruption roution,therefore the accurate estimated value of meter\|factor is acqured.
