Inverted U-Tube Manometer Calculator & Guide
An inverted U-tube manometer is a device used to measure pressure differences. The calculation of the pressure difference involves understanding the height of the liquid column, its density, and the acceleration due to gravity.
- Enter the height of the liquid column (h) in meters.
- Enter the density of the liquid (ρ) in kg/m³.
- Enter the acceleration due to gravity (g) in m/s².
- Click the ‘Calculate’ button to see the pressure difference and a visual representation.
The formula to calculate the pressure difference (P) is:
P = ρ * g * h

Expert Tips
- Always ensure the liquid in the manometer is the same as the fluid being measured.
- Clean the manometer regularly to prevent errors due to contamination.
- Calibrate the manometer regularly to maintain accuracy.
What is the units of pressure difference?
The pressure difference is in Pascals (Pa).
