Ezindaweni ezahlukahlukene zokulinganisa ukugeleza kwezimboni, lapho ubuchwepheshe obuyinkimbinkimbi njenge-electromagnetic noma i-ultrasonic flowmeters bubusa khona ekusetshenzisweni okukhulu, ama-rotameter (noma ama-float flowmeters) akha indawo ebalulekile. Lawa madivayisi amancane, angabizi kakhulu ahamba phambili ekulinganiseni amazinga okugeleza amancane kuya kwaphakathi koketshezi namagesi, enikeza ubulula obungenakuqhathaniswa, ukusebenziseka kalula, kanye nokuthembeka—okwenza abe yinto ebalulekile emalabhorethri, ezindaweni zokukhiqiza, kanye nezinhlelo zokuqapha imvelo. Ngokungafani nezinye izindlela zobuchwepheshe obuphezulu ezidinga ukulinganiswa okuyinkimbinkimbi noma imithombo yamandla, ama-rotameter asebenza ngesimiso esiqondile somzimba, enikeza ukusebenza okulinganayo nokunakekelwa okuncane.
Enhliziyweni yomklamo we-rotameter kukhona isimiso sendawo eguquguqukayo, indlela elula kodwa ephumelelayo exhumanisa ukugeleza koketshezi nendawo ye-float ehambayo. Idivayisi yakhiwe izingxenye ezimbili ezibalulekile: ithubhu elibekwe ngokuqondile, elinciphile (elinwebeka kancane kusukela phansi kuya phezulu) kanye ne-float (noma i-rotor) elingana kahle ngaphakathi kwethubhu. Lapho uketshezi (uketshezi noma igesi) lungena ethubhu lusuka phansi, lugeleza phezulu luzungeze i-float, ludala umehluko wokucindezela ophakamisa i-float. Njengoba i-float ikhuphuka, isikhala esiphakathi kwe-float nodonga lwangaphakathi lwethubhu siyanda—kunciphisa ijubane loketshezi kanye nokucindezela okuphezulu okusebenza ku-float. I-float ekugcineni izinza ngokuphakama okulingana nesilinganiso sokugeleza: amazinga aphezulu okugeleza aphakamisa i-float phezulu, kuyilapho amazinga aphansi okugeleza evumela ukuthi ihlale phansi. Isikali esilinganisiwe ngaphandle kwethubhu sivumela opharetha ukuthi bafunde ngqo izinga lokugeleza ngokusekelwe endaweni ye-float.
Enye yezinzuzo ezihlaba umxhwele kakhulu zama-rotameters ubulula bawo kanye nezindleko eziphansi. Ngokungafani nama-flowmeter kagesi adinga amandla kanye nama-electronics ayinkimbinkimbi, noma ama-flowmeter amakhulu anezinhlelo zezinzwa eziyinkimbinkimbi, ama-rotameter awanazo izingxenye ezihambayo ngaphandle kwe-float. Lo mklamo omncane uhumusha ekwehliseni izindleko zokukhiqiza, okwenza kube ukukhetha okungabizi kakhulu kwezinhlelo zokusebenza eziqaphela isabelomali—njengokuhlolwa kwelebhu, ukulinganisa amakhemikhali amancane, noma ukwelashwa kwamanzi omthamo ophansi. Ngaphezu kwalokho, ukuntuleka kwawo kwama-electronics kusho ukuthi angasebenza ezindaweni ezikude noma ezingenawo ugesi, inzuzo ebalulekile yemisebenzi yokuqapha insimu efana nokuthatha amasampula emvelo noma izinhlelo zokuphakelwa kwamanzi zasemakhaya.
Ama-Rotameter akhanya kalula ekufakweni nasekusetshenzisweni kwawo. Awadingi ukuqhutshwa kwepayipi eliqondile (isidingo esivamile sama-turbine noma ama-flowmeter e-ultrasonic) futhi angafakwa ngokuqondile ngokusetha okuncane—okufanelekela izikhala eziqinile noma izinhlelo ezikhona lapho ukulungiswa kabusha kuyinselele. Ukufundwa okubonakalayo okuqondile kuqeda isidingo sokuboniswa kwedijithali noma ama-data logger, okuvumela opharetha ukuthi bahlole amazinga okugeleza ngokushesha. Kuzinhlelo zokusebenza ezidinga ukuqapha okuhlala njalo, ama-rotameter amaningi angafakelwa izesekeli zokuzikhethela njengezinzwa zamagnetic noma ama-optical detector ukuze aguqule indawo ye-float ibe isignali kagesi (isb., 4-20mA) yokuhlanganiswa nezinhlelo zokulawula—ukuhlanganisa ubulula namakhono ayisisekelo okuzenzakalelayo.
Elinye amandla abalulekile ukuguquguquka kwazo kuzo zonke izinhlobo zoketshezi. Ama-Rotameter angalinganisa kokubili uketshezi (isb., amanzi, uwoyela, amakhemikhali) kanye namagesi (isb., umoya, i-nitrogen, igesi yemvelo), ngemiklamo eyenzelwe izakhiwo ezithile zemidiya. Isibonelo, ama-rotameter e-glass-tube asetshenziselwa uketshezi olucacile, olungaboliyo njengamanzi noma umoya, okunikeza ukukhanya ukuze kube lula ukubonakala kokuntanta. Ama-rotameter e-Metal-tube (ngokuvamile enziwe ngensimbi engagqwali noma ithusi) aklanyelwe uketshezi oluboliyo, amagesi anomfutho ophezulu, noma ukusetshenziswa kwezinga lokushisa eliphezulu—njengokulinganisa izinyibilikisi zezimboni noma umusi. Izinto ze-float nazo zingenziwa ngokwezifiso: Ama-PTFE float okumelana namakhemikhali, ama-float ensimbi engagqwali okusetshenziswa ngomfutho ophezulu, noma ama-float e-ceramic oketshezi oluqothulayo—okuqinisekisa ukuhambisana nezidingo ezahlukene zezimboni.
Ezisetshenzisweni ezisebenzayo, ama-rotameter afakazela inani lawo kuzo zonke izimboni. Emalabhorethri, asetshenziselwa ukulawula ukugeleza kwamagesi athwalayo ku-chromatography yegesi noma ukulawula ukungezwa kwama-reagent ekuhlolweni kwamakhemikhali—lapho ukulinganisa okunembile nokuphansi kokugeleza kubalulekile khona. Ekukhiqizeni, aqapha ukugeleza kwamafutha okugcoba emishinini noma uketshezi olupholile ezinhlelweni zamathuluzi, avimbele umonakalo wemishini kusukela ekugcotshweni okunganele noma okungaphezu kwamandla. Kubunjiniyela bezemvelo, alinganisa ukugeleza kwamakhemikhali ezitshalweni zokwelashwa kwamanzi amdaka (isb., ama-coagulant noma ama-disinfectants) noma ukugeleza komoya ezinhlelweni zokuqapha ukukhishwa kwegesi—okusekela ukuhambisana nezindinganiso zomthetho.
Nakuba ama-rotameter enemikhawulo—awanalo iqiniso eliphelele ngamanani aphezulu okugeleza (ngokuvamile angaphezu kuka-100 m³/h koketshezi) futhi azwela izinguquko ekuminyaneni koketshezi noma i-viscosity—amandla awo adlula kakhulu la maphutha ekusetshenzisweni kwawo okuqondiwe. Ngamazinga okugeleza amancane kuya kwaphakathi, lapho ubulula, izindleko, kanye nokuthembeka kubekwa phambili, ama-rotameter awanakuqhathaniswa. Intuthuko yesimanje, njenge-smart rotameters enezikali zedijithali kanye nokuxhumeka okungenantambo, iye yandisa kakhulu ukusetshenziswa kwayo, okuvumela ukuqapha okude ngenkathi kulondolozwa izinzuzo zayo eziyinhloko.
Ekuphetheni, ama-rotameter awubufakazi bamandla obunjiniyela obulula. Anikeza ukulinganisa ukugeleza okuqhubekayo nokuthembekile ngaphandle kobunzima noma izindleko zobuchwepheshe obuthuthukisiwe, okwenza abe ithuluzi elibalulekile emalabhorethri, ezimbonini, nasemisebenzini yasensimini emhlabeni jikelele. Kungakhathaliseki ukuthi asetshenziselwa ukuqapha okubonakalayo okuyisisekelo noma ahlanganiswe ezinhlelweni ezenzakalelayo, ama-rotameter ayaqhubeka nokudlala indima ebalulekile ekuqinisekiseni ukuphathwa koketshezi okusebenzayo, okuphephile, nokuhambisanayo kuzo zonke izimboni.
