Uma idatha yokulinganisa ye-ultrasonic flowmeter ishintshashintsha njalo futhi ingakwazi ukuboniswa ngokuzinzile, inkinga ingase ivele kulezi zilinganiso ezine ezilandelayo, futhi kungathathwa izinyathelo eziqondiwe:
Ubukhulu 1: Ukuphazamiseka kwendawo yokufaka. Okokuqala, hlola ukuthi imishini iseduze yini nemithombo enamandla yokuphazamiseka kwe-electromagnetic njengezimoto ezinamandla aphezulu kanye nama-frequency converter, okuzothinta ukudluliswa kwezimpawu ze-ultrasonic. Uma ibanga liseduze kakhulu (ngaphansi kwemitha eli-1), i-flowmeter idinga ukugcinwa kude nomthombo wokuphazamiseka, noma kufanele kufakwe ipuleti lokuvikela lensimbi phakathi kwe-flowmeter nomthombo wokuphazamiseka. Ngesikhathi esifanayo, hlola ukuthi ipayipi linayo yini i-vibration enamandla, njenge-resonance ngesikhathi sokusebenza kwephampu yamanzi. I-shock absorber ingafakwa ebhulakini lokufaka i-flowmeter ukuze kuncishiswe umthelela wokudlidliza ekulinganisweni.
Ubukhulu 2: Izinkinga zokufakwa kwe-probe. Hlola ukuthi i-probe inamathele eduze yini nepayipi. Uma i-probe ikhululekile noma i-coupling agent isindala, ukudluliswa kwesignali ngeke kuzinzile. Ngalesi sikhathi, cisha imishini, susa i-probe, hlanza uthuli namafutha ebusweni be-probe kanye nepayipi, phinda usebenzise i-coupling agent ekhethekile (qinisekisa ukuthi awekho amabhamuza omoya ku-coupling agent), bese ulungisa i-probe ngokuqinile. Uma uqinisa amabhawodi okulungisa, sebenzisa amandla afanayo ukuze ugweme ukuguquguquka kwe-probe. Ngaphezu kwalokho, hlola ukuthi isikhala sokufakwa kwe-probe siyahlangabezana yini nezidingo zemishini. Ububanzi obuhlukene bepayipi buhambisana nezikhala zokufakwa ezahlukene. Ungabheka ithebula lezikhala encwadini yemiyalelo yemishini ukuze ulungise.
Ubukhulu 3: Izinguquko esimweni esimaphakathi. Uma indawo elinganisiwe iqukethe inani elikhulu lamabhamuza nokungcola, noma izinga lokushisa kanye ne-viscosity yendawo eshintsha ngokuzumayo, ukunemba kokulinganisa kuzothinteka. Ngalesi sikhathi, qaphela isimo sendawo ephayiphini. Uma kunamabhamuza, i-valve yokukhipha ingafakwa endaweni ephezulu yephayiphi; uma kunokungcola okuningi, isihlungi kufanele sifakwe phezulu kwe-flowmeter (ukunemba kokuhlunga kunqunywa ngokwesimo esimaphakathi). Ngesikhathi esifanayo, qinisekisa ukuthi imishini ifanele yini izinga lokushisa kanye ne-viscosity yendawo yamanje. Uma idlula ibanga elifanele, i-probe noma imodeli ehambisanayo idinga ukushintshwa.
Ubukhulu 4: Izilungiselelo zepharamitha yemishini. Faka isikhombimsebenzisi sepharamitha yemishini bese uhlola ukuthi amapharamitha anjenge-“imodi yokulinganisa”, “ububanzi bepayipi” kanye “nesivinini somsindo ophakathi” asethwe kahle yini. Isibonelo, uma ububanzi bepayipi langempela buyi-DN100 kodwa bubekwe ngephutha ku-DN80, kuzokwenzeka ukushintshashintsha kwedatha. Amapharamitha angalinganiswa kabusha ngokwesimo sangempela sendawo. Eminye imishini isekela umsebenzi “wokulinganisa okuzenzakalelayo”; ngemva kokusebenza, imishini izozivumelanisa ngokuzenzakalelayo nezimo zokusebenza zamanje futhi inciphise ukushintshashintsha kwedatha.
