LWGY系列智能一体化涡轮流量计产品介绍

LWGY系列智能一体化涡轮流量计在涡轮流量传感器的基础上,采用电池供电,增加了现场显示功能。传感器与显示计算组成一体化新型流量测量仪表。可就地显示瞬时流量和累计总量。可广泛应用于石油、化工、轻工、食品等行业的液体流量测量。

LWGY系列智能一体化涡轮流量计产品特点

1高精确度,一般可达±1%R±0.5%R,高精度型可达±0.2%R

2、重复性好,短期重复性可达0.05%~0.2%正是由于具有良好的重复性,如经常校准或在线校准可得到极高的精确度,在贸易结算中是优先选用的流量计;

3、具备仪表系数三点修正,智能补偿仪表系数非线性,并可进行现场修正;

4、所有有效数据掉电后保持10年不丢;

5、范围度宽,中大口径可达120,小口径为110

6、结构紧凑轻巧,安装维护方便,流通能力大;

7、适用高压测量,仪表表体上不必开孔,易制成高压型仪表;

8、专用型传感器类型多,可根据用户特殊需要设计为各类专用型传感器,例如低温型、双向型、井下型、混砂专用型等

9、可制成插入型,适用于大口径测量,压力损失小,价格低,可不断流取出,安装维护方便。

LWGY系列智能一体化涡轮流量计工作原理

流体流经传感器壳体,由于叶轮的叶片与流向有一定的角度,流体的冲力使叶片具有转动力矩,克服摩擦力矩和流体阻力之后叶片旋转,在力矩平衡后转速稳定,在一定的条件下,转速与流速成正比,由于叶片有导磁性,它处于信号检测器(由永久磁钢和线圈组成)的磁场中,旋转的叶片切割磁力线,周期性的改变着线圈的磁通量,从而使线圈两端感应出电脉冲信号,此信号经过放大器的放大整形,形成有一定幅度的连续的矩形脉冲波,可远传至显示仪表,显示出流体的瞬时流量和累计量。在一定的流量范围内,脉冲频率f与流经传感器的流体的瞬时流量Q成正比,流量方程为:Q=3600×f/k 式中:

f——脉冲频率[Hz]

k——传感器的仪表系数[1/m3],由校验单给出。若以[1/L]为单位Q=3.6×f/k

Q——流体的瞬时流量(工作状态下)[m3/h]

3600——换算系数。
