A simple U-tube manometer can measure negative gauge pressures.

A simple U-tube manometer can measure negative gauge pressures. Correct Answer True

The height of the manometric fluid in a U-tube manometer in the test column would fall if there is a positive gauge pressure. The height would increase if there is a negative gauge pressure. It is possible to measure negative gauge pressures with a U-tube manometer. However, the negative pressure cannot fall below -1 Bar.
