i-electromagnetic flowmeteringase ibe nezinkinga ezithile ohlelweni lokusebenzisa langempela, futhi kunezizathu eziningi zokwehluleka. Namuhla, umkhiqizi we-Flowmeter Q&T Instrument uzothatha ukuthi uqonde ukuthi i-flowmeter ye-electromagnetic iwenza kanjani umsebenzi "wokuzisiza".
1. I-Zero Drift
Mayelana nenkinga ye-zero drift ebangelwa ukushintsha kwezinga lokushisa kwemvelo, ubuchwepheshe bokunxeshezelwa kwezinga lokushisa semukelwe ukuxazulula le nkinga. Okusho ukuthi, ingxenye yokutholwa kwezinga lokushisa elizungezile yengezwa kumjikelezo, futhi inani lokushisa elitholiwe lidluliselwa ku-microcomputer ye-single-chip ngesikhathi sangempela. I-microcomputer ye-single-chip ilungisa amanye amapharamitha kusekethe ngokuya ngokushintsha kwezinga lokushisa, okunciphisa kakhulu umthelela wokushintsha kwezinga lokushisa kwemvelo kusekethe. Umphumela we-zero drift.
2. Inani lesignali elilinganisiwe alinembile
Umthombo oyinhloko ukuphazamiseka kwefrikhwensi yamandla. Kuboniswa ukuthi ukusetshenziswa kobuchwepheshe besampula bokuvumelanisa kungacindezela ngempumelelo isignali yokuphazamiseka kwemvamisa yamandla kusignali yokulinganisa. Ukuze uthole amasignali ahlukene okuphazamisa, izindlela zokuhlunga ezifana nokuhlunga kwesinqumo sohlelo, ukuhlunga okumaphakathi, ukuhlunga incazelo ye-arithmetic, ukuhlunga okumaphakathi okunyakazayo, nokuhlunga okumaphakathi okunesisindo kungasetshenziswa ukuthola imiphumela emihle.
3. Kuvela ukuphahlazeka nezinhlamvu ezidukile
Mayelana nokuphahlazeka nemiphumela ebolile edalwe ukulandelana okungalawuleki, isiteshi sokuqapha ukusebenza kokulandelana sengezwe esiteshini. Ukusebenza ukuthi uma ukulandelana kwe-microcontroller kungalawuleki, kungatholwa ngesikhathi futhi lonke uhlelo lusethwe kabusha, ukuze umsebenzi wokulandelana ubuyiselwe kuthrekhi enembile futhi kuvimbele ukuphahlazeka , Ukuthumela kwe-Garbled.
