用自行设计的流量计实验台, 对50 mm 口径旋涡进动流量计上不同的压电式压力传感器安装方式进行了试验L 结果表明, 传感器安装对测量结果有显著影响L 并给出了较佳的传感器安装方式和传感器的设计准则L关键词: 旋涡进动流量计; 压电传感器; 流体振动; 安装方式; 设计原则Abstract: A <50 mm p ro to type sw irlm eter is developed fo r the experience in st rum en t designed. Experim en t s w ere perfo rm ed to study set t ing m ethod of sen so r inf luence on m easu re of sw irlm e2 ter. Two ax isymm et rical set t ing p iezoelect ric p ress sen so rs ob tained the velocity p ressu re signals of vo rtex p recession in sw irlm eter. M ajo r f indings in experience are described as fo llow s. F irst, the set t ing m ethod of p iezoelect ric p ressu re sen so r inf luence on sw irlm eter m easu re is clear. Sec2 ond, the best set t ing of p iezoelect ric p ressu re sen so r in sw irlm eter and m ethod of design sen so r are advanced.Key words: sw irlm eter; p iezoelect ric p ressu re sen so r; f lu id o scillat ion; set t ing m ethod; design p rincip le
