超声波流量计在供水计量中存在着较大的相对误差.本文通过多次24 h 测试分析误差与流速的关系及产生原因,提出流速变化较大的计量点应采取24 h 累计流量或多点流速比对法消除流量计相对误差的方法.

Ultrasonic flowmeter has the relatively large error in the measurement of water supply. This paper through many times of 24h test analyzes relationship and causes of error and velocity, puts forward the measuring point velocity changes in the larger should take 24 h accumulative flow or multipoint ve-locity matching method to eliminate flowmeter relative error.
