CONVAL^® can calculate pressure and temperature-dependent properties according to various methods.

Almost all the program modules require a certain amount of information about the pressure and temperature-dependent properties of the medium being used in the process.

CONVAL^® is capable of calculating this process data automatically for a large number of media (approx. 1000) in connection with the calculation program.

Three different calculation methods for process data are offered at present, namely:

1. Using approximation equations based on a property database for physical constants.
2. By interpolation on the basis of a property database for actual measurement series.
3. With the help of extremely accurate thermodynamic equations of state.
