 Apipeareawithasteadyflowpatternmustbeselectedforthesensingpoint.There

mustnotbeanycomponentsthatdisturbtheflowdirectlyupstreamanddownstream

ofthesensingpoint,e.g.,orificeplates,expanders,bends,junctions,shut‐offdevices,

etc.

 Theflowrateatthesensingpointshouldnotexceedapprox. 25 m/s,dependingonthe

systemconditions.

 Inthecaseofspecificsystemcircuits(suchas gasregulatinglinesforgasengines)andin

thecaseofgasburners,flowrateshigherthan25 m/smaybeallowedfollowingcon‐

sultationwiththemanufacturer.

 Withinalow‐pressurerangeofuptoapprox. 250 mbar,amaximumflowrate

of approx. 15 to 20 m/sisrecommendedatthesensingpoint.Onacase‐by‐casebasis,

andfollowingconsultationwiththemanufacturer,evenlowerflowratesmaybeal‐

lowed.
