弯管流量计特点

         弯管流量计属于差压式流量测量系统,当流体通过弯管传感器时,由于流体受到传感器的束缚,迫使流体按照弯管的曲率在管道中作类似的圆周运动,流体产生的离心力使传感器的内外侧壁产生压力差△P(P1-P2 )。该离心力的大小与流体的流速V、密度ρ、及所做圆周运动的曲率半径R等等因素有关,该压力差通过差压变送器检测出来,转换为4-20Ma信号输出送给上微机或二次仪表。
  弯管流量计特点:适用的测量范围广,重现性和测量精度高,无附加压力损失,耐磨性能好、使用寿命长,对直管段要求不高(满足前5D后2D);可采用直接焊接式安装,减轻了现场维护工作量,运行费用低,可实现温压在线补偿。
