The program's interface provides fields for inputting the operating temperature and pressure, base specific gravity, pipe size and ID, flow rate and type and differential pressure. I found that there are two calculation variables that the program does not take into account - The Reynolds Number correction and the Expansion factor. If no compressibility correction factor is entered, greater inaccuracies will occur for gas calculations with high operating pressures. Still, Daniel Orifice Flow Calculator provides useful assistance in the calculation of orifice diameters for estimation purposes.

Use this calculator to quickly calculate the actual flow rate through the orifice plate flow meter with only a few inputs. This calculator performs the flow rate calculation from the measured pressure drop caused by the orifice plate inserted in the pipeline.

The calculator is suitable for liquids and perfect gases, a subsonic flow of single phase fluid. It is not applicable for pulsating flow. The pipeline should be circular. The calculator is not applicable for rectangular ducts.

This calculator is not suitable for multiphase fluids, like a flow of liquids that contain solid particles or flow of liquids that contain undissolved gases. Also, it is not suitable for gases that are not ideal, i.e., gases that don't relate to the ideal gas law.

To calculate flow rate, you have to enter the orifice plate throat diameter as well as pipe interior diameter, together with fluid properties - density and viscosity. For a gas as flowing fluid, instead of the density, you can enter gas constant, pressure and temperature at actual conditions. Density is then calculated using a perfect gas state equation. You should enter density on real flow conditions - pressure and temperature.

If the orifice plate properties or flow conditions are not according to the ISO 5167-2 calculator displays the message. If you want to do calculation regardless of the limitations in the standard, you can choose not to use ISO constraints in the calculation.

Daniel Orifice Flow Calculator uses the ASME MFC-3M 1989 equation to determine the rate of fluid flowing for 2" and larger pipe sizes. It will display the respective ratio, or orifice diameter to pipe diameter, for a given set of input variables. Provided for estimation purposes only, this simple, single-window program assists in sizing an orifice meter and bore size, though the calculated values for the beta ratio are approximate, typically within 2% - 5% for gases and steam, and 1% for liquids. The program's interface provides fields for inputting the operating temperature and pressure, base specific gravity, pipe size and ID, flow rate and type and differential pressure.

The calculator uses the differential pressure measurement principle to calculate the flow rate. It accurately measures the difference in pressure of fluid across an orifice plate installed in the pipeline through which the fluid is flowing. The orifice plate size and shape are preselected based on the nature of the fluid, its flow rate, and other factors such as temperature and pressure.

The software interface is user-friendly and provides an easy-to-use system for selecting variables such as fluid type, pipe size, orifice plate size, temperature, pressure, and so on. It then calculates the flow rate based on these inputs and presents the results in a clear and concise format.

The 'Orifice Flow Calculator' is an easy to use, one page program to assist in sizing an orifice meter and bore size. For a given set of input variables, the program will calculate the bore & beta ratio, the differential pressure, or the flow rate for 2" & larger pipe sizes. The Orifice Flow Calculator is provided for estimation purposes only.

Flow calculator is a small, compact and useful tool which helps in doing flow related calculations very easy and fast. The main advantage of this software is its compactness and size. It does not contain any irrelevant option in itself. The simple interface only contains three text boxes. These text boxes correspond to the inside diameter of the cylindrical pipe, velocity and the volumetric flow rate. Any two quantities when filled in the text boxes can be used to calculate the third one. Inside diameter can be provided in any one two units ie. inches and milimeters. Similarly, velocity can also be provided in any of four units such as inches/second, feets/second, meters/second and centimeters/second. The third quantity can be expressed in any of the units such as cubic feet/sec, cubic feet/minute, cubic feet/day, US gallon/sec, US gallon/sec, UK Barrels/sec, UK Barrels/sec, US Oil Barrels/sec and US Federal Barrels/sec. Another feature of the software is that it can give the calculated result accurate up to eight decimal places.

It is often required to measure the flow rate for a given experiment. A flow' meter can be included in the flow' loop for flow' rate measurements. Various flow meters can be chosen depending upon the specific application. There are differential-pressure meters such as an orifice plate, Venturi meter, and flow' nozzle; force meters such as rotameters; and momentum meters such as turbine flow meters.

Obstruction Flow' Meters: Commonly used obstruction flow meters include the orifice plate, Venturi meter, and flow nozzle. They measure the pressure drop due to an intentional reduction of flow area, as shown in Figure 2.14. They can be placed in the pipe for direct flow rate measurements. An example is included demonstrating how' to calculate the flow rate from the measured pressure drop (P, - P2) across an orifice flow' meter.

An orifice flow meter (the top and bottom drawings of Figure 2.14) is used to measure a fluid flow rate. Different sizes of the orifice bore diameter can be used to measure various ranges of the flow' rate. The mass flow' rate of the fluid is directly proportional to the pressure drop across the orifice: increasing the flow' rate increases the pressure drop. The size of the orifice plate must be selected in conjunction with the manometer or transducer used for this differential pressure measurement. If the flowrate is too large, the differential pressure could exceed the range of the transducer. If the flow'rate is too small, measurement of the small pressure difference

Because orifice meters are widely used for flow rate measurements in many industries, a number of standards are available for their construction, implementation, and usage. For example, the location of the upstream and downstream pressure taps is not arbitrary. As the fluid travels through the orifice, an area of separation is formed downstream of the plate. The pressure difference across the orifice will vary depending on where the downstream pressure measurement is taken. Also, the orifice plate should be constructed so the loss through the plate is predictable. With the calculation of the mass flow rate, multiple constants are used based on the construction of the meter, and if the plate is not constructed according to industry standards, the constants may not be applicable, and therefore, the flow rate will be measured incorrectly.

A well-known company supplying flow meters across the oil and gas industry is Emerson. While this company deals with many automation tasks, their Daniel flow meters are well-regarded for their performance and ease of operation. The Daniel orifice plates are fabricated according to industry standards with tight manufacturing tolerances. To support these meters, they have made available the Daniel Orifice Flow Calculator software. This calculator can be used w'ith a wide variety of fluids, pipe sizes, and orifice sizes. While this software package is convenient to use, researchers should be aware of w'hat is required to accurately calculate the mass flow rate from this type of meter.

FlowCalc32 is a Windows orifice plate sizing program for calculation of various differential pressure flow measurement devices. The program can be used to calculate orifice plates, venturi and nozzle flow meters or to calculate the effects of changes in operating conditions, variation of pipe and primary device bore diameters etc.

An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice[1] but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reaches its maximum and the pressure reaches its minimum. Beyond that, the flow expands, the velocity falls and the pressure increases. By measuring the difference in fluid pressure across tappings upstream and downstream of the plate, the flow rate can be obtained from Bernoulli's equation using coefficients established from extensive research.[2] ff782bc1db
