How it works
The application calculates pressure value in pressure balance system, when the force equal to action of gravitational force from given weights is applied to the piston. It also features reverse operation of calculating required weights for given pressure value.

Calculation results
For proper use of calculation results in practice dead weight of the piston and weights receiving device of pressure balance shall be taken into account.
