InstruCalc 9.0 calculates the sizes of control valves, flow elements, and relief devices; produces data sheets for calculated items; and prepares instrument summaries and uses data sheets as a database for generating reports.
It consists of 4 different modules as below:
-
Module 1 – Control Valves: For liquid, gas, steam, and two-phase flow using the ISA formulas.
-
Module 2 – Flow Elements: For flow and restriction orifice plates; flow nozzles and venturies; gas, steam, vapor, and liquids; flange, radius, pipe, and corner taps.
-
Module 3 – Relief Devices: For pressure-relief devices, rupture discs, and breather valves.
-
Module 4 – Auxiliary Programs: For determining line pressure drops for gas and liquids, calculates compressibility factor, flowing density, vapor pressure and temperature, latent heats at pressure and temperature, and physical properties of mixtures.
