ＣＷＬ型涡街流量计在使用过程中出现故障 ,会导致计量不准 ,甚至无法计量 ,这对提高工艺水平和贸易结算极为不利。本文介绍ＣＷＬ型涡街流量计的故障分析及处理方法。　　现象 1 通电后无指示 ,无输出信号(1)流量积算仪无 2 4Ｖ输出 ,应检查积算仪。(2 )接线有误或断线 ,如电 CWL-type vortex flowmeter in the process of failure, will lead to measurement uncertainty, or even impossible to measure, which is to improve the level of technology and trade settlement is extremely unfavorable. This article describes the CWL vortex flowmeter fault analysis and processing methods. Phenomenon 1 no indication after power, no output signal (1) Flow Totalizer no 24V output, check the calculator. (2) Wrong connection or disconnection, such as electricity
