On any given day, I analyze the manometer levels for air displacement, friction and velocity.

我的日常就是分析压差数值，包括排气量、摩擦力、和速率。

Which is where manometers and barometers come in.

这就是压力计的用武之地。 气压计是大气压计。

Then, we covered how manometers and barometers measure pressure.

然后我们讲了压力计的作用机理 气压计是压力表。

A manometer is just a U-shaped tube with a fluid inside.

压力计是一个形状像 字母 U 充满液体。

Once the needle is inserted into the spinal canal, it's attached to a manometer, which is a device that measures the CSF pressure.

刺入腰椎管的针与流体压力计相连，来测量脑脊液压力。
