采用差压变送器直接测量流量，输出电流与被测流量将是非线性关系。
By using transducers of differential pressure to measure flux directly, the relation between current output and measured flux will be nonlinear.
若在差压变送器的电磁反馈机构中串接一个电流平方器，就会使输出电流与被测流量呈线性关系，便于显示、记录、调节。
When connected in series a squarer to electromagnetism feedback system of differential pressure their relation will be linear, which is convenient to display, record and adjust.
