MC-II Plus EXP Flow Analyzer8. The upper line of the display will show the prompt rAtE.dLY. The lower line of the display willshow the flow rate filter value in terms of the number of samples desired to reach 90% of thefinal value. The factory default setting is “nonE.” The available settings are nonE, 5, 10, and 20.Press INCR until 10 is displayed. Then, press ENTER. (See the section Setting Flow Rate Filterto change the flow rate filter.)9. The upper line of the display will show the prompt inP.SEnS with the lower line of the displayshowing the input sensitivity in terms of millivolts peak-to-peak (mV). The factory default inputsensitivity is 20 mV. The available settings are 20, 40, 60, 80, 100 and 120 mV. If the lower lineof the display shows 20 (for 20 mV) then press ENTER. If any other value is shown, press INCRuntil 20 isdisplayed, then press ENTER. (See the section Setting Input Sensitivity to change the inputsensitivity.)10. The upper line of the display will show the prompt PULS.oUt with the lower line of the displayshowing oFF or on (factory default is oFF). Press INCR until oFF is shown since the pulseoutput is to be disabled. Press ENTER. (See the section Configuring Pulse Output to configurethe pulse output feature.)11. The upper line of the display will show the prompt 4-20.oUt with the lower line of the displayshowing oFF or on (factory default is oFF). Press INCR until oFF is shown since the 4-20 mAoutput circuitry is to be disabled. Press ENTER. (See the section Configuring the 4-20 mA RateOutput to configure the 4-20 mA output feature.)12. The upper line of the display will show the prompt CodE with the lower line of the displayshowing oFF or on (factory default is oFF). Press INCR until oFF is shown since the securitycode feature is to be disabled. (See the section Setting a Security Code to enter a securitycode.) Press ENTER. Since this is the last step of calibration, the MC-II Plus EXP automaticallyreturns to the Run Mode. The ACCESS key of the MC-II Plus EXP does not have to be pressedto return to Run Mode unless Calibrate Mode is exited before the last step of calibration. Seethe data entry Flow Chart in Appendix C.Gas Measurement Using Preprogrammed Units of MeasureWhen the gas volume is to be expressed in thousands of cubic feet (MCF) and the flow rate isto be expressed in thousands of cubic feet per day (MCF/D), the MC-II Plus EXP calculatesthe divisor and rate multiplier, compensating the volume and flow rate to standardconditions. The information needed to calibrate the MC-II Plus EXP is the decimal pointsetting for the volume display, the decimal point setting for the meter factor, the meter factorexpressed in pulses per actual cubic foot (PACF), atmospheric pressure, base pressure,average flowing pressure, base temperature, average flowing temperature and supercompressibilityfactor (optional). An outline of the user prompts and the steps followed for thistype of calibration is provided below:1. Press the ACCESS key to enter the Calibrate Mode.2. At the prompt tot Eng, press INCR until MCF is selected. Press ENTER.3. At the prompt tot d.P, press INCR to change the decimal point position for the volume.Press ENTER.12 October 2009
MC-II Plus EXP Flow Analyzer4. At the prompt SEt tot, press INCR to toggle between yES or no. If no is selected, pressENTER. If yES is selected, see the section Presetting Volume.5. At the prompt PACF d.P, press INCR to set the pulses per actual cubic foot decimalpoint. Press ENTER.6. At the prompt Ent.P.ACF, use the INCR and STEP keys to enter the meter factor inpulses per actual cubic foot. Press ENTER.7. At the prompt bAro.Psi, use the INCR and STEP keys to enter the barometric pressurein pounds per square inch absolute (PSIA). Press ENTER.8. At the prompt bASE.Psi, use the INCR and STEP keys to enter the base pressure inPSIA. Press ENTER.9. At the prompt Ent.Psig, use the INCR and STEP keys to enter the average flowingpressure in pounds per square inch (PSIG). Press ENTER.10. At the prompt bASE F, use the INCR and STEP keys to enter the base temperature indegrees Fahrenheit (F). Press ENTER.11. At the prompt Ent F, use the INCR and STEP keys to enter the average flowingtemperature in degrees F. Press ENTER.12. At the prompt Ent FPv, use the INCR and STEP keys to enter the supercompressibilityfactor. Press ENTER.13. At the prompt rAtE.dLY, press INCR to set the flow rate filter. Press ENTER.14. At the prompt inP.SenS, press INCR to set the input sensitivity. If the input sensitivity isset as desired, press ENTER. If the input sensitivity needs to be changed, see the sectionSetting Input Sensitivity.15. At the prompt PULS.oUt, press INCR to select oFF or on for the pulse output feature. IfoFF is selected, press ENTER. If on is selected, see the section Configuring PulseOutput.16. At the prompt 4-20.oUt, press INCR to select oFF or on for the 4-20 mA output feature.If oFF is selected, press ENTER. If on is selected, see the section Configuring the 4-20mA Rate Output.17. At the prompt CodE, press INCR to select oFF or on for the security code feature. IfoFF is selected, press ENTER. If on is selected, see the section Setting a Security Code.A detailed example of this method, using actual meter factors and step-by-step data entry isbelow.Example: Gas Measurement Using Preprogrammed Units of MeasureThe MC-II Plus EXP will be mounted on a 2” NuFlo standard range gas turbine meter. The meterfactor is 129.42 pulses per actual cubic foot. The volume units of measure will be in thousands ofstandard cubic feet (MCF) and the flow rate units of measure will be in thousands of standard cubicfeet per day (MCF/D). The average flowing pressure is 120 PSIG. The average flowing temperatureis 50 degrees Fahrenheit. The base pressure is 14.73 PSIG and the base temperature is 60 degreesFahrenheit. The atmospheric pressure is not known but the elevation of the installation is 1000 feetabove sea level. The 4-20 mA output, pulse output and security code are to be disabled.
