摘　　要：简单介绍了插入式涡街流量计的构成及点流速计型的插入式涡街流量计的标定方法。简要分析了用水泵流量比对,便携式超流量计比对方法的缺点,提出了插入式涡街流量计的标定修正比对的快速查表法,实例证明该方法是有效可行的。The composition of insertion Vortex flowmeter and the method of calibration of point flow velocity type insertion vortex flowmeter are introduced in brief, The disadvantages of intercomparisons by using of water pump flow or portable ultrasonic flowmeter are analyzed. The fast speed table looking up method for intercomparison of calibration and correction of insertion flowmeter is proposed. The practical example shows that this method is effective and feasible.
