Option 17 — Configured for Shifting Gases
Option17hasdual‐purposefunctionalitythatisconfiguredperuserspecifications.Thetwo
functionalitiesaremutuallyexclusive,andthespecifiedfunctionalitycannotbechanged.
Important ThissectioncontainsInformationforconfiguringtheflowmeterforashifting
gascomposition.Informationforselectingfromtheavailablelistofmultiple
gascalibrationcurvesstartswith“Option17—ConfiguredforMultipleGases”
onpage 4‐43.
AnoptionalfeatureavailablewithKurzflowmetersistheabilitytoadjustforshiftinggas(also
referredtoas“binarygas”)compositionsortoselectadifferentpredefinedgascalibration.
• Ashiftinggascompositionisagasmixwithonlythepercentagesofthegaseswithinthe
mixchangingbasedonthekeygaswithinthemix.
• Multiplegascalibrationssupportuptofiveuniquegasesorgasmixes.

Makesureyouarereferringtothecorrectsetoffeatureparameters
forOption17.
Shifting Gas Composition
Shiftinggascompositionsarecommoninbiogasapplicationswheretheamountofmethane,
hydrogen,andcarbondioxidecanshift basedonseasonalchanges,biomasscontent,andrateof
decomposition.
Thegascompositioncanbechangedtwowa ys:
• Manuallybyenteringapercentconcentrationofthekeygas.
• Automaticallyadjustingthepercentconcentrationofthekeygas
throughthe4‐20mAexternalinputsignalreadbytheflowmeter.
Thefactorysettingfortheshiftinggascompositionfeatureisconfiguredsothatthepercent
concentrationofthekeygasisenteredmanually,anditissetto50%
concentrationofthekeygas.
Makesuretoproperlywiretheflowmeterelectronicsbeforechangingthesourceofthegas
adjustmenttoanexternalsource.RefertotheKurzHardwareReferenceGuide,AppendixAfor
