无零点 meaning in Chinese

inferred-zero

Since it has the advantage of no moving components , impulse signal output , strong medium adaptability , high measurement accuracy , wide measurement range , low - pressure drop , no zero drift and easy to maintenance , it is wide accepted that the vortex type fluid oscillatory flowmeter is ideal flowmeter in the measurement of gas , liquid , steam and mix / corrosive fluid
这类的流量计兼有无运动部件，脉冲数字输出，计量不受被测流体性质影响，测量准确度较高，量程比宽，无零点漂移，压力损失小，便于安装维护等优点，是测量气体，液体，蒸汽，混合型和腐蚀性流体的理想的流量计。
