Lefoo I-flowmitera

I-flowmeter, imitha ekhombisa izinga lokugeleza elinganiswa kanye / noma inani eliphelele likaketshezi esikhathini esikhethiwe. Kalula nje, iyinsimbi esetshenziselwa ukukala ukugeleza koketshezi kuyipayipi noma esiteshini esivulekile.

Ama-flowmeters aphinde ahlukaniswe ngama-browmeter wokugeleza kwengcindezi, ama-rotor flowmeters, ama-throttle flowmeter, ama-slat flowmeters, ama-volumtric flowmeter, ukugeleza kwe-electromagnetic, ama-ultrasonic flowmeter, njll. Ukuhlukaniswa ngokuphakathi: i-flowmeter negesi yokugeleza.

Isilinganiso sokusebenzisa

Isilinganiso sokugeleza sisetshenziswa kabanzi ekukhiqizeni izimboni nezolimo, ukwakhiwa kwezokuvikela kuzwelonke, ucwaningo lwesayensi, ukuhweba kwamanye amazwe, nemikhakha ehlukahlukene yempilo yabantu. Ekukhiqizeni imboni ka-petroleum, kusuka ekukhishweni kukawoyela, ukuthutha, ukuncibilikisa nokucubungula kuya ekuthengisweni kwezohwebo, isilinganiso sokugeleza sihamba kuyo yonke inqubo. Asikho isixhumanisi esingahlukaniki nokukala kokugeleza, ngaphandle kwalokho ukukhiqizwa okujwayelekile nokuhweba embonini kaphethiloli ngeke kuqinisekiswe. . Embonini yamakhemikhali, ukulinganisa kokugeleza okungalungile kuzodala ukungalingani kwesilinganiso sokusabalalisa kwezinto zamakhemikhali, ayikwazi ukuqinisekisa ikhwalithi yomkhiqizo, futhi izingozi ezingathi sína zokuphepha zokukhiqiza zizokwenzeka. Ekukhiqizweni kwemboni yamandla kagesi, ukulinganisa nokulungiswa kokugeleza koketshezi, igesi, umusi kanye neminye imidiya kudlala indima ebalulekile. Ukunemba kokulinganisa kokugeleza akuyona into ebaluleke kakhulu kwezomnotho kuphela ukuqinisekisa ukuthi izitshalo zamandla zisebenza ngaphansi kwamapharamitha afanele, kepha futhi nokuthuthukiswa kwamayunithi wokushisa okuphezulu, ukucindezela okuphezulu kanye namandla amakhulu, isilinganiso sokugeleza sesiphenduke isixhumanisi esibalulekile sokuqinisekisa ukusebenza okuphephile kwezikhungo zamandla. Uma ukugeleza kwamanzi okusheshayo kwama-boilers amakhulu kuphazanyiswa noma kuncishiswa, ingadala i-boiler eyomile noma i-payipi iqhuma ingozi. Lokhu kudinga ukuthi idivayisi yokulinganisa ukugeleza akufanele ilinganise ngokunembile kuphela, kepha futhi ikhiphe isignali ye-alamu ngesikhathi. Ekukhiqizweni kwemboni yensimbi nensimbi, ukulinganiswa kokugeleza kwamanzi okujikelezayo nomoya - mpilo (noma umoya) kwinqubo yokwenza insimbi ingenye yamapharamitha abalulekile ukuqinisekisa ikhwalithi yomkhiqizo. Embonini ekhanyayo, ukudla, izindwangu nezinye izimboni, isilinganiso sokugeleza naso asihlukaniki.

Ama-transducers asetshenziswa kakhulu yi-clip-on ne-plug-in. I-monophonic ultrasonic flowmeter ilula ngokwesakhiwo futhi kulula ukusisebenzisa, kepha lolu hlobo lwe-flowmeter lunokungavumelani kahle nezinguquko ekusatshalalisweni kokugeleza. Ukuthuthukiswa okusheshayo kobuchwepheshe be-microelectronic nobuchwepheshe bamakhompiyutha kukhuthaze kakhulu ukushintshwa kwezinsimbi, futhi sekuvele ama-flowmeter amasha. Kuze kube manje, kuthiwa amakhulukhulu ama-flowmeter afakwe emakethe, futhi izinkinga eziningi ezinzima ekusetshenzisweni kwensimu kulindeleke ukuthi zixazululwe. Umsebenzi wobuchwepheshe besimanje wokulinganisa ukugeleza ezweni lakithi sekwephuzile. Isethwe ekugcineni komfula phezulu kwesiteshi sokugeleza kokulinganisa 6 futhi kuhlobene nezimbobo eziyi-11 no-12 ukunciphisa ukugeleza koketshezi ukuthi kube yimen kuqinisekiswe emigodini 11 no-12; Ingxenye yokulawula isilinganiso 19 isetshenziselwa ukukala isikhathi sokusabalalisa kwamagagasi e-ultrasonic phakathi kwe-ultrasonic transducers 8 no-9;

Izinyathelo

I-flowmeter kufanele izame ukugwema izinto ze-ferromagnetic nemishini enezinkambu eziqinile zikagesi (njengezimoto ezinkulu, ama-transformer amakhulu, njll.), ukuze kuvimbele inkambu kazibuthe ukuthi ithinte inkambu kazibuthe esebenzayo kanye nesiginali yokugeleza yenzwa. Intambo yesiginali yokuhamba kanye nocingo lokujabulisa phakathi kwenzwa ne-scoop converter. Kodwa-ke, kusukela ekuhlaziyweni kwezinto ezilimele kuphutha lombani, Iningi lamandla aphezulu okwenziwe kanye namanje e-inrush okubangelwe yiphutha kwethulwa kulayini wokuphakela ugesi wegumbi lokulawula, futhi ezinye izindlela ezimbili zimbalwa. Njengoba i-electromagnetic flowmeter inamathuba amaningi okukala ukuqina okumisiwe noma ukungcola kunamanye ama-flowmeter, amathuba okuhluleka okubangelwe ungqimba lokunamathela odongeni lwangaphakathi aphezulu. Uma ukuqhutshwa kwengqimba yokunamathela kufana nokweketshezi. Ukwehluleka kwesikhathi esijwayelekile kokuthunyelwa kuvame ukubangelwa ukufakwa okungafanele.
