Kufotokozera Kwachidule:

"Critical Flow Venturi Sonic Nozzle Gas Flow Standard Device" ndi muyezo wogwirizanitsa ndi kusamutsa mayunitsi oyendera, ndipo ndi chipangizo choyezera kuchuluka kwa zinthu zomwe zimatsata, kusamutsa mtengo ndi kuzindikira zida zodziwira kuchuluka kwa mpweya. Zida zimenezi zimagwiritsa ntchito nozzle ya critical flow Venturi ngati tebulo lokhazikika ndi mpweya ngati njira yoyesera kuti zitsimikizire, kuwerengera ndi kuyang'anira mita zosiyanasiyana zoyezera kuchuluka kwa mpweya.

Chotumizira mpweya wothamanga kwambiri komanso chotumizira kutentha chomwe chili mu chipangizochi chimayesa kuthamanga kwa mpweya ndi kutentha asanayambe komanso atatha kuyesedwa kwa nozzle ndi flowmeter, komanso kuthamanga kwa nozzle kumbuyo. Dongosolo lowongolera limasonkhanitsa ndikugwiritsa ntchito magawo osiyanasiyana nthawi yeniyeni panthawi yowunikira. Kompyuta yotsika imaweruza ndikuwunika kuchuluka kwa deta yomwe yakwezedwa ndi chotumizira ndikusunga. Panthawiyi, deta yomwe yasokonezedwa ndi chotumiziracho imachotsedwa. Pambuyo polandira deta yapakati kuchokera ku kompyuta yotsika, kompyuta yapamwamba imasunga mu database ya zotsatira zotsimikizira zotumizira, ndipo nthawi yomweyo imachita chiweruzo chachiwiri ndikuwunika deta yosungidwa kuti iwonetsetse kuti deta yomwe ikukhudzidwa pakuwerengera ndi yolondola komanso yodalirika, ndipo kukonzako kumachitikadi.

Mu kompyuta ya chipangizochi, ntchito yokhazikitsa kapena kusintha deta yoyambira ya chipangizocho imayikidwa. Kuphatikiza pa database yotsimikizira zotsatira za transmitter, database yoyambira ya nozzle imapangidwanso kuti isunge magawo monga nambala ya serial ndi coefficient ya outflow ya nozzle iliyonse yokhala ndi chipangizocho. Ngati deta yotsimikizira nozzle isintha kapena nozzle yatsopano yasinthidwa, wogwiritsa ntchito amangofunika kusintha deta yoyambira.
