Flow Element Design, Selection & Analysis 

instruCalc features more than 70 routines associated with control valves, ISO flow elements, relief valves and rupture disks, and calculates process data at flow conditions for up to 64 fluids in either mixtures or single components. 

instruCalc calculates the sizes of control valves, flow elements and relief devices; produces data sheets for calculated items, and prepares instrument summaries and data sheets as a database for generating re-ports. 

instruCalc will calculate, display and print graphs of its calculations. Graphs available for Control Valves include: valve Cv versus flow; valve pressure drop versus flow;. Flow Element graphs include flow and differential values. 

instruCalc operates in both the US Customary System of Units or SI Units for both volumetric or mass flows
