Performance equations allow engineers to write calculations that include fluid properties or models of process units. Equations can also be used as mathematical expressions to calculate values that cannot be obtained directly from the plant instrumentation, such as " compensated flows."
Additional uses of PI-PE include:
Heat and material balances
Real-time cost accounting
Grade based costing
PI-PE Steam is an optional module that includes functions that calculate the thermodynamic properties of steam within Performance Equations. These functions are converted from the software distribution of ASME's Steam Tables, 6th Edition. The functions support both English units and SI units.
PI Totalizer Subsystem
The PI Totalizer is a separate subsystem that simplifies making common calculations, such as totals, averages, minimums, maximums, range and standard deviations. PI Totalizer is also able to count events.
