Izikali zeleveli ye-Ultrasonic zisebenza ngokusekelwe kubuchwepheshe be-ultrasonic kanye nezimiso zokulinganisa isikhathi sendiza.Nakhu okufingqiwe kokuthi kusebenza kanjani:
I-Ultrasonic Pulse Generation: Igeji yeleveli ye-liquid ikhipha ama-pulses e-ultrasonic kusuka ku-transducer noma inzwa efakwe esitsheni esiwuketshezi noma ngaphezulu kwesiqukathi.I-transducer iguqula amandla kagesi abe amagagasi e-ultrasound, ahamba aye phansi ngomoya noma ngegesi ngaphezu koketshezi.
I-Liquid surface reflection: Lapho ama-pulses e-ultrasonic efika endaweni ewuketshezi, aboniswa kancane emuva ku-transducer ngenxa yomehluko we-acoustic impedance phakathi komoya noketshezi.Isikhathi esisithathayo ukuze i-pulse ebonisiwe ibuyele kunzwa sihlobene ngokuqondile nebanga lenzwa ukusuka endaweni ewuketshezi.
Isikhathi Sokulinganiswa Kwendiza: Imitha yeleveli ikala isikhathi esisithathayo ukuze i-pulse ye-ultrasonic ihambe isuka kunzwa iye endaweni ewuketshezi futhi ibuye.Ngokusebenzisa isivinini esaziwayo somsindo emoyeni (noma enye imidiya) kanye nesikhathi esilinganisiwe sokundiza, igeji yezinga loketshezi ibala ibanga ukuya phezulu koketshezi.
Ukubalwa Kwezinga: Uma ibanga lokuya endaweni ewuketshezi selinqunyiwe, igeji yezinga isebenzisa lolu lwazi ukubala izinga loketshezi esitsheni noma emkhunjini.Ngokwazi i-geometry yesiqukathi, i-level gauge ingakwazi ukunquma ngokunembile izinga ngokusekelwe ebangeni elilinganisiwe.
Okukhiphayo nesibonisi: Ulwazi lweleveli ebaliwe luvamise ukukhishwa njengesignali ye-analogi, iphrothokholi yokuxhumana yedijithali (efana ne-4-20 mA noma i-Modbus), noma ikhonjiswe kusixhumi esibonakalayo sendawo, okuvumela opharetha ukuthi aqaphe futhi alawule izinga emkhunjini.
Sekukonke, ama-gauge e-ultrasonic level ahlinzeka ngesilinganiso sezinga le-liquid esingathinteki, esithembekile, nesinembile ezinhlobonhlobo zezimboni nezentengiso.Zifanele ukusetshenziswa emathangini, eziseleni, emithonjeni nakwezinye izindawo zokugcina uketshezi kanye nezinhlelo zokucubungula.
