Lefoo I-flowmeter

Izicelo ze-Lefoo Flowmeter embonini nasekuphileni kwansuku zonke

Ukukalwa kokugeleza kwamanzi kusetshenziswa kakhulu ekukhiqizeni kwezimboni nezolimo, ekwakhiweni kwezokuvikela izwe, ocwaningweni lwesayensi, ekuhwebeni namanye amazwe, kanye nasezimbonini ezahlukene zokuphila kwabantu. Ekukhiqizeni imboni kawoyela, kusukela ekukhipheni uwoyela, ekuthutheni, ekuncibilikiseni nasekucubunguleni kuze kufike ekuthengiseni ngokuhweba, ukukalwa kokugeleza kuhamba kuyo yonke inqubo. Akukho xhumanisi olungenakuhlukaniswa nokukalwa kokugeleza, ngaphandle kwalokho ukukhiqiza okujwayelekile nokuhwebelana embonini kawoyela ngeke kuqinisekiswe. Embonini yamakhemikhali, ukukalwa kokugeleza okungaqondile kuzodala ukungalingani kwesilinganiso sokusatshalaliswa kwezingxenye zamakhemikhali, kungakwazi ukuqinisekisa ikhwalithi yomkhiqizo, futhi kuzokwenzeka izingozi ezinkulu zokuphepha ekukhiqizeni. Ekukhiqizeni imboni kagesi, ukukalwa nokulungiswa kokugeleza koketshezi, igesi, umusi nezinye izinto ezisetshenziswayo kudlala indima ebalulekile. Ukunemba kokukalwa kokugeleza akugcini nje ngokuba nokubaluleka okukhulu kwezomnotho ukuqinisekisa ukuthi izikhungo zikagesi zisebenza ngaphansi kwezimo ezingcono kakhulu, kodwa ngokuthuthuka kwamayunithi okushisa okuphezulu, ingcindezi ephezulu namandla amakhulu, ukukalwa kokugeleza sekuphenduke isixhumanisi esibalulekile sokuqinisekisa ukusebenza okuphephile kwezikhungo zikagesi. Uma ukugeleza kwamanzi kwesikhashana kwamabhoyili anamandla amakhulu kuphazamiseka noma kuncipha, kungadala izingozi ezimbi zokoma kwababhoyili noma ukuqhuma kwamapayipi. Lokhu kudinga ukuthi idivayisi yokukala ukugeleza ingagcini nje ngokukala ngokunemba, kodwa futhi ikhiphe isignali yesixwayiso ngesikhathi. Ekukhiqizeni imboni yensimbi nensimbi eqinile, ukukalwa kokugeleza kwamanzi ajikelezayo nomoya-mpilo (noma umoya) enqubweni yokwenza insimbi kungenye yezinto ezibalulekile zokuqinisekisa ikhwalithi yomkhiqizo. Ezimbonini ezilula, ezokudla, ezindwangu nezinye izimboni, ukukalwa kokugeleza nakho akunakuhlukaniswa.

Ama-transducer asetshenziswa kakhulu yi-clip-on ne-plug-in. I-monophonic ultrasonic flowmeter inesakhiwo esilula futhi ilula ukusetshenziswa, kodwa lolu hlobo lwe-flowmeter alukwazi ukuzivumelanisa kahle nezinguquko ekusatshalalisweni kokugeleza. Ukuthuthuka okusheshayo kobuchwepheshe be-microelectronic nobuchwepheshe bamakhompiyutha kukhuthaze kakhulu ukushintshwa kwezinsimbi, futhi ama-flowmeter amasha aqhamuka ngobuningi. Kuze kube manje, kuthiwa amakhulu ama-flowmeter asefakwe emakethe, futhi izinkinga eziningi ezinzima ekusetshenzisweni endaweni kulindeleke ukuthi zixazululwe. Umsebenzi wobuchwepheshe besimanje bokukala ukugeleza ezweni lakithi uqale emuva kakhulu. Ubekwa engxenyeni ephezulu yesiteshi sokugeleza esikalwayo 6 futhi maqondana nezimbobo 11 no-12 ukunciphisa ukugeleza koketshezi oluzokalwa lungene ezimbotsheni 11 no-12; ingxenye yokulawula ukukala 19 isetshenziselwa ukukala isikhathi sokusabalala kwama-ultrasonic phakathi kwama-ultrasonic transducers 8 no-9;

Iziqondiso Zokufaka Nokusetshenziswa Kwama-Lefoo Flowmeters

I-flowmeter kufanele igweme izinto ze-ferromagnetic kanye nemishini enamandla amakhulu kazibuthe kagesi (njengama-motor amakhulu, ama-transformer amakhulu, njll.), ukuze kuvinjelwe amandla kazibuthe ukuthi angathinti amandla kazibuthe okusebenza kanye nesiginali yokugeleza kwenzwa. Intambo yesiginali yokugeleza kanye nentambo yokukhuthaza phakathi kwenzwa nesiguquli se-scoop. Nokho, ekuhlaziyweni kwezingxenye ezilimele enhlekeleleni yombani wezulu, iningi lamandla aphezulu asheshisayo kanye nomsinga ogobhozayo obangelwa yinhlekelele angeniswa entanjeni kagesi yegumbi lokulawula, kanti ezinye izindlela ezimbili zincane. Njengoba i-electromagnetic flowmeter inamathuba amaningi okukala izinto ezilengayo noma ukungcola kunezinye ama-flowmeter, ithuba lokwehluleka okubangelwa ungqimba olunamathelayo odongeni lwangaphakathi likhulu kakhulu. Uma i-conductivity yongqimba olunamathelayo ifana neye-liquid. Ukwehluleka okuvamile kwesikhathi sokuvivinya ngokuvamile kubangelwa ukufakwa okungafanele.
