  1. “The explanation of the U-tube manometer in this article about manometers was incredibly helpful! Now I understand its significance in measuring pressure. Great content!”

  2. As someone new to the subject of manometers, I really appreciated the detailed explanation of U-tube manometers in this article.

  3. I’m a bit confused about the difference between absolute pressure and gauge pressure. Can someone please explain?

    1. Sure! Absolute pressure is the total pressure at a given point, including atmospheric pressure. Gauge pressure, on the other hand, only measures the pressure above atmospheric pressure. So, gauge pressure = absolute pressure – atmospheric pressure.

    1. Good question Neil, The unit of measurement used for pressure in manometers is usually expressed in “inches of water column” (inH2O) or “millimeters of mercury” (mmHg).
