摘要
文中叙述的实验装置,利用系统自身的压差,采用一倒U型差压计来测流量,使测量管路结构简练、紧凑,克服了用流量计测量带来的缺点。
the paper introduces a kind of test unit, which is used to measure flow rate using the pressure difference of system itself, This equipment makes measure tube become elgance and coherence, and it overcomes shortages that are brought by using flow indicator in this test unit to measure flow rate.
