Pipes diameters between 50mm and 1000 mm, This calculator is valid for pipe diameters of less than 40 mm (other restrictions are given below). These orifice meters are used commonly in natural gas custody transfer and other monitoring and process control applications. This Excel spreadsheet calculates the flowrate from a small-bore gas orifice meter using the ASME MFC-14M-2001 standard. This orifice plate creates a: restriction to flow, while pressure taps on the upstream and downstream side of the restriction provide the necessary differential pressure.
Orifice meters use the pressure loss across a constriction (that is, the orifice plate) in a pipe to determine the flowrate. Small-Bore Gas Orifice Meter Flow Calculator.

You'll find a spreadsheet that models a liquid orifice meter here. Varies the guess value of Re until it matches the calculated value ofīy carefuly altering the equations (and the parameters used by Goal Seek), you could also solve for any other variable - for example, you could find the pressure drop for a specific flowrate (let me know if you need help in implementing this). The spreadsheet provides an initial guess value for Re. This process is automated with a button - just fill in the parameters, click a button, and some VBA initiates Goal Seek with the correct settings Excel's Goal Seek functionality is used to iteratively solve the equations for the flowrate.
The calculation is iterative: you need Re to calculate C, you need V to calculate Re, but you need C to calculate V. This is a screen grab of part of the spreadsheet. The equations use the ideal gas law to calculate the gas density (you could override this with your own value), and are only valid for pipes with internal diameters from 50 mm to 1000 mm, and for pressure ratios greater than 0.75. For corner taps, L 1 = L 2= 0, for D-D/2 taps L 1 = D 1 and L 2= D 1/2, and for flange taps L 1 = L 2= 1 inch. The JSE Orifice Calculator will calculate the flow of a given gas (Natural Gas. There are three standard tap positions that determine the values of L 1 and L 2, as illustrated below. JINSUNG orifice meters are a simple, economical method of measuring air.
NATURAL GAS ORIFICE METER CALCULATOR HOW TO
important calculation we need to understand is how to design an orifice meter plate. Orifice meters use the pressure loss across a constriction (that is, the orifice plate) in a pipe to determine the flowrate. GAS METERING In SI units, From tables, Y 1.003 2 In field units. A photograph of an orifice plate used to measure the flow of natural gas to. Units of measure are both in SI and English system. Fluid is considered as incompressible, so density (rho) and temperature (T) are constant through tube. AGAs calculation of the volume flowing through the orifice plate assumes. Orifice plate calculator can be used for both liquids and gases. This Excel spreadsheet calculates the flowrate from the pressure drop across a gas orifice meter with the equations defined in ISO 5167. Excel formulas use the ideal gas law to calculate the density of a gas for. Reverse installation of an orifice plate in a natural-gas orifice meter can.
