Well Type Manometer



Well Type Manometer
A common form of manometer seen in calibration laboratories is the well type, consisting of a single vertical tube and a relatively large reservoir (called the well) acting as the second column. Due to the well’s much larger cross-sectional area, liquid motion inside of it is negligible compared to the motion of liquid inside the clear viewing tube. For all practical purposes, the only liquid motion is inside the smaller tube. Thus, the well manometer provides an easier means of reading pressure.no longer does one have to measure the difference of height between two liquid columns, only the height of a single column.
