the other column travels down to obtain the pressure
Should one column travel further than the other column,
due to minor variations in tube I.D. or to pressure
imposed, the accuracy of the pressure reading thus
obtained is not impaired. The U-tube Manometer is a
primary measuring device indicating pressure by the
difference in the height of two columns of fluid. The
fact that one column travels further than the other does
not affect the accuracy of the reading.
