InstruCalc 6.1
Flow Element Design and Analysis


InstruCalc 6.1 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.


 Control Valves

Gas, liquid and two-phase flow. Noise prediction and cavitation.

 Flow Elements

ISO and AGA orifice plates, nozzles, venturis; annubars; integral flow orifice meters; vortex, target, rotameter and elbow meters.

 Pressure Relief Devices

Valves, rupture disks, tank vents.

InstruCalc 6.1 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.

Units: InstruCalc 6.1 allows YOU to select any set of engineering units, including your own customized set. Units can be mixed, matched and changed in the middle of a calculation.

Fluids database: InstruCalc 6.1 calculates process data at flow conditions for 64 fluids in either mixtures or single components. File can be updated with additional fluids.

Orifice calculations: InstruCalc 6.1 calculates the orifice size, flowrate or differential range, which enables the user to select the flowrate with optimum accuracy. It provides the recommended size and corrects the orifice size accordingly. Process data can be converted individually or jointly with a simple "click of the mouse."

Data sheets: InstruCalc 6.1 contains pro-forma data sheets for each element.

What's new in InstruCalc 6.1?

  • The Control Valve sizing program is upgraded to "ANSI/ISA-75.01.01-2002"dated 3 July 2002 which now contains sizing for miniature valves.
  • The Relief Valve sizing program is upgraded to "API RP 520" 7th Edition January 2002 which now includes 2 phase flow sizing.
  • Tank venting is updated to "API std 2000" 5th Edition April 1998."
  • The Flow Element sizing program now combines all flow calculations into one program and provides a means for transferring data between the calculations for optimum selection.
  • Data files are now Microsoft Access
  • There are now separate tables for calculation data, units' data, data sheets, pressure drop calculations, chemical properties composition data and water hammer data. This allows for data to be available for manipulation.
  • Provision has been provided to transfer Version 5.0 data to Version 6.0.
