FlowSoft's ORIFICE for Windows, flow element sizing software package, allows you to quickly and easily size all types of flow elements, in either English or S.I. units. By computerizing the sizing of flow elements, you can save time and improve the accuracy of your calculations.

There are over 600 fluids in the program’s fluid property database. Simply select the fluid name and ORIFICE for Windows automatically computes the density, viscosity, and other fluid properties.

English or S.I. Units

Select virtually any unit of measure in either English or S.I. units. You can even "mix and match" units. For example, you can select differential in inches of water column and flow in cubic meters per second.

Beta, Flow, or Differential Calculations

The program will calculate for Beta Ratio, Flow Rate, or Differential Pressure. The "back calculation" feature is useful for sizing an existing flow element for different process conditions.

ORIFICE for Windows will size all types of concentric, eccentric, and segmental orifice plates at all tap locations, flow nozzles, venturi’s, low loss venturi’s, and restriction orifice plates. Just select the desired flow element and ORIFICE for Windows will use the proper equations to quickly and easily size the element.

Automatic Units Conversion

All common units of measure for fluid properties, pressure, flow, temperature, differential pressure, etc. are supported by ORIFICE for Windows. No time consuming and error prone data conversions are required. You can "mix and match" units. For example, enter pressure in pounds per square inch and flow in kilograms per hour. 

ORIFICE for Windows will monitor your input data and display possible data entry errors. When a error is detected, a message instantly pops up, warning you of a potential problem.

Program checks for possible errors. Such as the pressure drop exceeding critical drop or sonic velocity. This is a common problem with restriction orifices and can cause significant errors if not addressed.

The program automatically checks the results of a calculation to be sure that the data are within limits.

Pipe Data

Built in pipe size data for over 300 sizes and schedules of carbon steel and stainless steel pipe. The user simply selects the nominal pipe size, schedule and material from a pop-up menu. ORIFICE then supplies the necessary pipe data. If you are using a honed meter section or one with special diameter pipe, you can enter the actual inside diameter directly.

Fluid Properties Database

Fluid properties on over six hundred (600) fluids including air, steam, and water are instantly available. ORIFICE for Windows will quickly compute the physical properties for most fluids without having to resort to property tables and look up charts. This saves time during data entry and prevents look up errors. For fluids not in the database, there are a number of internal routines to compute the physical properties of a fluid.

ORIFICE for Windows computes the permanent pressure loss at both normal and maximum flow rates. This allows the user to quickly and easily determine the energy required by the flow element. Compare various types of flow elements to see if a more energy efficient flow element might be a better choice.

ORIFICE for Windows will automatically compute the correction factor for a drain or vent hole if one is used. The program will select the hole diameter automatically or it can be entered manually.

Save & Recall Data

Flow element data can be stored for easy retrieval and access. The user can set the default conditions for a calculation and the desired units of flow, pressure, temperature, density, etc. are automatically used. It is not necessary for the user to input these items during the data entry phase. If changes are required, the user need only change the data and recalculate without having to reenter all the data.
