1) zero level
零电平
2) zero-crossing detection of electrical level
过零电平检测
1.
The results indicate that, even in case of high concentration of carbon dioxide, the flowmeter still maintains high measurement accuracy due to the techniques employed including zero-crossing detection of electrical level, averaging of multiple transit-time measurements randomly taken, and so forth.
文章设计了实验用以测试CO2的浓度含量对超声波气体流量计测量精度的影响,实验结果表明,由于在流量计中采用了"过零电平检测"、"随机多次测量声时后平均"等技术措施,即使在CO2的浓度较高的情况下,流量计依然可以保持在较高的测量精度。
