Installation for Network Version

Stop and read these instructions first. Do not install the software until you understand all the installation

instructions. This is critical or you will have issues. We have added a new install option that may be of interest to

you.

InstruCalc 8 Network Installation Instructions

Following are two (2) alternative sets of network installation instructions.

The first set will be familiar to previous users of InstruCalc as it is basically the same as version 7. It uses a mapped drive to the license file location on the server.

The second set of instructions uses a share (UNC) to the license file location on the server and will be a lot less steps. Whichever install you decide to use, the network installation instructions must be followed for this version of InstruCalc to work in a network environment.

This version of InstruCalc (8.X) includes a license metering software that monitors the number of simultaneous users. You may install the software on as many client machines as you wish, but only the licensed number of simultaneous users will be able to use the software at any one time.

Please use the CD labeled Windows 7 64-bit Install for installation on Windows 7 64-bit workstation installation and the CD labeled Windows XP/Vista/7 32-bit Install on workstations that have Windows XP, Windows Vista or Windows 7 32-bit OS.

NOTE: Consider backing up your current database files if this is an upgrade so that this new install does not delete or overwrite those important files.Save and copy back in the folders CVData, FEData, PDData, RVData and Tables from the old InstruCalc Instrument Sizing Suite folder into the new install replacing the new ones.

xi

Traditional Mapped Drive Network InstallAs done in previous version 7.1

IMPORTANT: Please follow these installation instructions in the exact steps as described. Activate the server first and then go to the workstation setup. Some of the steps may be seem redundant but you still must do them. It is critical when mapping to the network that you map a drive letter (E, F, G, H, J, etc.) and not a UNC path. NOTE: A UNC (Universal/Uniform Naming Convention) path will not work wit this type of install.Also, the client workstation (and user) will need read/write access to the mapped drive location where you place the license file. Not only set the folder rights but also the user profile. The user will also need rights to the InstruCalc folder on the local drive.

If you wish to use a shared UNC install, please refer to the next set of install instructions.

xiii

Step 1 - Server Activation

1. Install the InstruCalc 8.1 software on a client workstation (not the network server) C drive using the appropriate (32-bit or 64-bit) install CD provided (run setup.exe).

2. Create and open a mapped drive to a location on your server where you want the InstruCalc license file to reside. Map the network drive location by specifying a drive letter (E, F, G, H, J, etc.). NOTE: A UNC (Universal/Uniform Naming Convention) path will not work.

3. Copy the InstruCalc7.ini license file and the Server setup file, InstruCalcserver.exe from the “Server” sub directory folder that you just installed on the client workstation (default location is “C:\InstruCalc Instrument Sizing Suite\Server) to a network drive location.

4. From the workstation, access the server drive and run the Server setup file that you just copied to the server (double click the InstruCalcserver.exe file) and you will get the following pop-up.

5. Click on OK to get to the next step (indicated by the 2 pop-ups below).

6. Select the Change Drive option on the lower pop-up screen for the license file path screen. Ignore the Enter password field. It is not used.

7. Select the Browse option on the above screen to get to the following screen. Note: the default drive and path for the CD installation may be pre-populated in the field.

8. On the License file path screen above, select the Server Drive where you just installed the InstruCalc7.ini file from the drive drop down menu and then click Select Path.

9. Once you have selected the correct drive (left click on drive:\path to highlight), select the Find InstruCalc.ini option button as noted on above screen and the result is shown below.

xvi

10. Choose the desired file, in this example below, h:\InstruCalc7.ini from the Files Found field (left click on file to highlight)

11. Click on the Select File button, then click on the Save button and then the OK button, and you will get the following pop-up. This operation creates file named InstDRV.txt on the server in the loction where the license file is. The content of this file is the mapped drive ( in this case it would read - h: ).

12. Select OK, on this Reload Menu. Your screen clears.

13. Go back into the server drive (like you did in step 4), run the Server setup file again (double click the InstruCalcserver.exe file) and you will get the following pop-up.

14. Select OK from this screen and the following 2 screens pop up.

xvii

15. Now select the Get New Licence option from the lower pop-up screen shown above. Ignore the

Enter Password field. It is not used.

xviii

17. Contact Gulf by email ([email protected]) or by phone (713) 520-4426 with the 2 user codes that are on your registration screen (as shown above) to receive the activation code (Reg Key 1 code). Please leave this screen open until activation.

18. Enter the Reg Key 1 number that you receive back from GPC in the Reg Key 1 field as shown below. In most cases you will not need a Reg Key 2 number.

19. After entering the number in the Reg Key 1 field, select Ok.

20. Server is Authorized

The server is activated. After closing the menu on the server you may now go to the activate workstation steps.

NOTE: The Server must be activated (all steps performed first) before the Work Stations can be activated.

xix

Step 2 - Work Station Activation

1. Copy the file InstDRV.txt just created on the server during the server setup Change Drive steps to the local drive replacing the existing one that it is the InstruCalc Instrument Sizing Suite folder. The two files (one on the server and one on the workstation) need to match contents.

2. Now run the InstruCalc software on the workstation that you installed the software on by right clicking and running as administrator (even if you have admin rights) the InstruCalcNetwork.exe from the C:\Program Files\InstruCalc Instrument Sizing Suite folder. You will get the following pop-up.

3. Select OK for the following screens.

Setting up Calculations in InstruCalc Ver. 8

Important information for all users of the new version 8. Information provided here is important for setting up the calculation screen with the units that you wish to use in your calculation.

This is author recommended procedure.

In previous versions of InstruCalc the user selected (setup) all of his input values and parameters from the menu bar:

Figure 1: Sample version 7 Calculation screen

xxxiii

In version 8, some of these same selections and additional ones are now made from the Change setup option button on the module calculation screen. Most noticeable and significant is the Units option has moved.

Figure 2: Sample Version 8 Calculation screen

The Change setup option is your first step in setting up your calculations. If you do not wish to use the default Mass – English units shown on the calculation screen, change the units in the Change setup screen first to the base units you want to use: Mass – English units, Volume – English units, Mass – SI units or Volume – SI units. After you have set your base units in the Setup option screen you may then use the individual buttons to fine tune your units.

xxxiv

The calculation form setup options include : Operating pressures, Liquid density options, available calculations, liquid or gas unit options, local or base conditions, pressure tap location, drain hole, etc. Options vary depending on the calculation screen you are working from.

Note this is the screen (as shown in Figure 3) used to preset your calculation units of choice as well as the other options available.. You can use the buttons on the calculation screen to set your initial units of choice but it is recommended that those buttons be used for fine tuning each line after initial units selection is made on the Change setup screen.

Figure 3: Sample Form Setup Options screen

For your calculations, if you plan on using units other than the default English Mass units, please use this screen to make your initial units setup. Once you have selected your desired units for calculation on this screen, you may fine tune the individual input units on the calculation screen using the line item buttons.

xxxv

Figure 4: Sample Version 8 Calculation screen

Use these buttons on the Calculation screen for fine tuning after you have made your base unit selection from the Change setup options screen. In this case we had changed the base units from Mass flow – English to Volume flow SI.

Navigating the Manual and General Program Information

The word “program” can mean a variety of things. InstruCalc 8.1 is a software program that contains four main programs that include calculation programs, a data sheet program and a summary program. Since this could get confusing, we will use other words to signify certain portions of InstruCalc. We will use the word "module" to refer to the four main programs: (1) Control Valves, (2) Flow Elements (ISO Flow Elements, AGA Orifice Plates, Flow Meters and Devices), (3) Relief Devices (Relief valves, Rupture disks and Tank Vents, and (4) Process Engineering Data (Pipe pressure loss, liquid waterhammer and fluid properties).

The options available in each module include sizing calculations, an option for producing a data sheet, and an option for generating summaries. These will be referred to as “programs” or “options.” The word “program” will also be used to refer to InstruCalc as a whole.

The more than 50 separate sizing programs will be referred to as “routines” (for example, “the Orifice Plate Concentric Flange Tap Sizing Routine”). This should help you differentiate between the parts of InstruCalc as we explain them in this manual.

This manual is divided into four main sections. Each section pertaining to one of the four main ‘modules’ of the program. Each section includes some general information about the ‘module’ (overview of program, program principles and considerations, program basis) and also the formulae and calculation routines for the included programs. Also included in each of the main sections are printouts of the Help files that are included with the program. The Help files may be accessed from any program screen by hitting the F1 key.

The following information on the following pages pertains to each of the four ‘modules’ of InstruCalc 8.1.

When opening any one of the four ‘modules’ of InstruCalc

you will first be directed to the module’s Main Menu screen and given the option of starting a new calculation or retrieving an existing record. This is done on InstruCalc’s new file option menu. This menu allows you to start a new calculation or retrieve/edit existing files.

New Calculation Option

To start a new calculation in the module of choice make the appropriate choice and select one of the available ‘buttons’ – New Calc, for Control Valves, Gas flow or Liquid flow for Flow Elements or the Go to Menu for Relef Valve and Process Data modules.

Selecting the New calc button in the Control Valve module takes you to a blank calculation screen to begin your new CV calculation.

Selecting the Gas flow or Liquid flow button in the Flow Element module takes you to the Flow Element Sizing Selection screen where the user chooses the element being sized. Once you click OK you will be taken to a blank calculation screen to begin your new calculation.

Selecting the Go to Menu button on the Relief Valve and Process Data modules take you to a Program Selection Menu where the user selects the program he wants to run and then clicking on OK to go to a blank calculation screen to begin the new calculation.

Database Location and Control / Existing Calculation Option

Selecting the DB on Default Path and then clicking the Open DB button in the DataBase Location and Control or Existing Calculation section of these menus will open the data base file on the default drive. This will activate the Record Selection and Selected Record data sections of the option.

xli

Now from the Record Selection area you can search for existing records of previously saved calculations to the default database file location. Options include: First which will display the first record in the database file showing basic information of it in the Selected Record Data fields; Last which will display the last record in the database file; < and > will scroll through the database records displaying each one in the Selected Record Data fields; Browse which will list all of the records in the database file that you can select from; Delete which will delete the selected file, Find tag which allows you to enter the file Tag you are looking for; Display calculation which will display the calculation screen of the selected record and Display data sheet which will display the data sheet of the selected record IF a data sheet was prepared and saved.

Close DB option will close the open database and disable the Record Selection and Selected Record Data areas of the menu.

If you select Browse for DB Path, you can browse for additional data base files that you may have created in alternate locations. Once selected, you will be able to search for and display previous calculations and data sheets.

xlii

Using the “Save As” option

Save As To file a record in a different file location (i.e. not the default location) “Save As” uses the Windows file access system to find the file and then save the data. However before you can use the “Save As” you must first create the new database in the alternate location using the steps described in the next section.The default drive is now becomes the new path. To get back to the original path either use “Save As” again or go back to the main menu (where you will see the path) if it is not the one you then close the Data Base and select and save the required path. “Save As” enables the user to retrieve a previous calculation and add it to the current work. The procedure for this is as follows, in the main menu call up the old data base and find the required calculation. In the calculation, change the tag number for the current project and using the “Save As” procedure, find the current project path and save the data.

Note: The default path will remain as the current project path.

xliii

Resetting Database file location or for Creating a New Database

Database files will be saved to the default location that is set during installation.

CVDB7.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\CVdataFEDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\FEDataPDDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\PDDataRVDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\RVData

If you want to save the files to a different location other than the default location, take the following steps. Do not use the standard File \ Save As function as it will not work for database reset/saving in InstruCalc.

You will need to set up the desired new location (path) prior to doing the calculations.

1. Open the module that you want to use. In this case we are opening Flow Elements:

xliv

From the main Flow Element Sizing Programs menu, choose Browse for DB Path in the DataBase Location and Control section on the menu screen.

The Data file pop-up box (as shown below) will appear with the default drive and path showing in the selection field.

2. In the Drive and path box, type in your new desired Drive and path, such as C:\Flow Elements\GPC

xlv

3. You will get some pop-ups asking to use the path elements you are entering, select OK. The Flow Element Sizing Programs main menu will come back up. 4. Select File, then Create database

5. The following Create New Database File pop-up Window will appear. Click on Yes as you are creating a newDatabase file. (There should not be one already existing in the newly created location).

xlvi

6. You will receive confirmation that the new database file has been created in the location you set.

7. Click OK. You may now save files to this location rather than the default location.

Changing the default database files in the other modules is performed in the same manner as above for Flow Elements module.

xlvii

Resetting Default Paths in InstruCalc

During installation, the default path for databases ( *DB.mdb), user unit files (*Lib.uns), printout headings (*HDG.TXT), and tables (*.txt) are set. Database files, user unit files, and printout headings files will be saved to the default locations shown below set during installation.

CVDB7.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\CVdataFEDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\FEDataPDDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\PDDataRVDB.MDB is saved in the default location - C:\Program Files\InstruCalc Instrument Sizing Suite\RVData

And the user editable tables are placed in the default location shown below as set during installation.C:\Program Files\InstruCalc Instrument Sizing Suite\Tables

If you install your software in a different location, you will have to reset the paths to all of these files in each module. We will show how in one module. All other modules are similar.

You will need to set up the desired new location (path) prior to doing the calculations.

Database file path, Printout headings default path, and User unit file path

1. Open the module that you want to use. In this case we are opening Control Valves:

xlviii

2. From the main Control Valve Selection and Sizing Programs menu, click on File and then choose File default path.

Options now are Database default path, User unit file default path, Printout headings default path and Tables default path.

xlix

Database default path

User Unit File default path

Printout headings default path

Tables default path

3. Select the first option, Database default path and you will get the Data file default path popup.

4. Select Browse to expand screen

5. From the left side of this screen, use the drop down options to find the drive and path where you installed your software.

6. Find the CVData folder and click on the Find Access Files button

l

7. Highlight the path in the large files found field and click on the Select File button. This will place your path in the Drive and path field at the top of the screen.

8. Click Save and OK to save this as the new default path for database files (i.e. the location you installed the software).

Do the same above steps for the new User unit file default path and Printout headings default path by selecting File/File default path and the corresponding option. The path will be the same for these as it was for the database file. These are stored in the *DB.MDB folder.

Resetting the path to the Tables folder

The steps for this are exactly the same as described above, only the path is different. The tables files are in the Tables folder in the path where you installed the software. In the example above, the path would be C:\Program Files\InstruCalc Instrument Sizing Suite 8.1 – Sgl\Tables

li

What InstruCalc does for youInstruCalc is a set of engineering programs for calculating control valve, relief valve, pressure-relief devices and various flow element sizes. It also prepares data sheets and instrument summary reports. It is an engineering program rather than an application program inasmuch as it is capable of determining the basic engineering data and requirements for the equipment rather than just using the data to determine the size required.

It consists of more than 74 programs divided into four main parts:

1. Control Valves for liquid, gas, steam, and two-phase flow using the ISA formulas. There are programs for calculating Cv and analyzing for citation within the valve, critical flow and flashing through the valve, and noise generated by the valve. The Cv is compensated where necessary for these and the piping geometry effects. Messages are displayed to guide you to an optimum valve selection.

2. ISO Flow Elements for flow and restriction orifice plates; flow nozzles and venturies; gas, steam, vapor, and liquids; flange, radius, pipe, and corner taps. Concentric, eccentric, segmental, quadrant edge, and conical plates. Calculates Beta ratio and orifice bore. Calculates flow for a selected bore. Compatible with ISO 5167 updated 2003.

3. Process Engineering Data programs that determines 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. These programs are useful for many other engineering activities such as centrifugal pump line loss calculations and determining pressure available for control valve pressure drop.

4. Relief Devices for pressure-relief devices, rupture discs, and breather valves. Liquid and gas application. Calculates API or ASME size for known flow, thermal expansion, and external fire. The external fire program has the option of either the API or the NFPA heat input methods. It also calculates the maximum flowrate for the selected valve and the maximum back pressure, which maintains the required flow as well as the relieving forces.

All device calculation and data sheet information can be saved for later recall. Printouts can be obtained of calculations, data sheets, and instrument summary reports. Any type of engineering unit can be used in the calculations. All conversion factors are contained within the programs tochange from one unit to another and to convert the values of the input data. Data can be imported and exported to and from the programs using ASCII files.

The program not only calculates the sizes of control valves, flow elements, and relief devices, but it also produces data sheets for the calculated items. In addition, it lets you prepare instrument summaries and use the data sheets as a database for generating reports.

What's new in InstruCalc Version 8.1

1. Engineering Standard upgrades Latest CV ISO Standard ANSI/ISA 75.01.01-2007 Pressure Relief Devices Program follows API 520 2009

2. Engineering Improvements Technique for showing cavitation in restriction orifices and venturi meters (Flow

Elements) Expanded vortex meter sizes available – up to size 36 (Flow Elements) Incorporation of Z-factor in gas-flow for sizing Flow Elements AGA8 option for Natural Gas in Flow Elements Added option to specify outlet pressure of orifice Flow Element. Added Text box at the bottom of the calculation for comments such as exit angle

of venture meters PRV Program provide option to calculate flow rate for a known size RV. Clarify status to show more clearly flashing, cavitation and choking of control

valves. Outlet of control valves - flow velocity at outlet flange Allow for Density input instead of Specific Gravity in all Programs Allow absolute and gauge units for all pressure inputs

3. Operational Improvements Program runs in Windows 7, 64 bit. Rearrange appearance of program – basic form set-up and day to day options –

removed them and clarified their use. Excel Import/Export for process data Database Print manager with options to print all of the database stored data and all

the calculations or any combination of them.

Old Data Files Are Still Compatible

Provision has been provided to transfer Version 5.x data to MS Access for Version 8 use .

New Ability to Transfer Data between Fileslv

Data files are now Microsoft Access. Version8.1 now saves all calculated data. 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.

We think you will find the InstruCalc 8.1 for Windows better than ever. If you have any suggestions, please write us and let us know. We will consider them for a newer version.
