转子式流速仪信号感测机构机件位置的调整

Adjustment of the Position of the Rotating Current Meter's Signal Sensing Mechanism

转子式流速仪传讯感测机构产生信号时,感测机构机件的相对位置会影响信号长度及稳定连续性,也会对流速仪的旋转造成一定的阻力,在低速检定或使用流速仪过程中,该阻力对流速仪的灵敏度影响较大。依据转子式流速仪在直线静水槽中的检定和实际使用经验,分析了流速仪信号长度及产生阻力的原因,提出了调整流速仪信号长度的方法,以确保流速仪信号稳定连续,减小对流速仪灵敏度的影响。

Rotor flow meter communications sensing mechanism generates a signal, sense of measuring the relative position of the body parts will affect the signal length and stable continuity, the rotation of velocity instrument some resistance, resulting in low speed verification or velocity instrument process, the convection resistance speed instrument sensitivity of larger. In this paper, based on the experience of the test and the practical use of the rotor type flow meter, the signal length and the resistance were analyzed.
