Mu buryo butandukanye bwo gupima amazi mu nganda, aho ikoranabuhanga rihambaye nka electromagnetic cyangwa ultrasonic flowmeters ari ryo rigenga ikoreshwa rinini, rotameters (cyangwa flue flowmeters) zikora ahantu heza cyane. Ibi bikoresho bito kandi bihendutse ni byiza cyane mu gupima amazi n'imyuka bito kugeza kuri biciriritse, bitanga uburyo bworoshye budasanzwe, bworoshye gukoresha, kandi bwizewe—bigatuma biba ingenzi muri laboratoires, mu nganda zikora, no muri sisitemu zo kugenzura ibidukikije. Bitandukanye n'ubundi buryo bugezweho busaba gupima cyangwa amasoko y'amashanyarazi, rotameters zikora ku ihame ryoroshye rya physique, zitanga imikorere ihamye kandi zidakorerwa isuku cyane.
Mu ishingiro ry'igishushanyo mbonera cya rotameter harimo ihame ry'ahantu hahinduka, uburyo bworoshye ariko bufite akamaro buhuza amazi atembera n'aho ikirere cyimuka. Iki gikoresho kigizwe n'ibice bibiri by'ingenzi: umuyoboro uhagaze, urambuye (waguka gato uhereye hasi ujya hejuru) n'umuyoboro urekura (cyangwa rotor) ujya mu mwobo ugororotse. Iyo amazi (amazi cyangwa gaze) yinjiye mu mwobo uturutse hasi, atembera hejuru akikije ikirere, bigatuma habaho itandukaniro ry'umuvuduko uzamura ikirere. Uko ikirere kizamuka, umwanya uri hagati y'ikirere n'urukuta rw'imbere rw'umuyoboro uriyongera—bigabanya umuvuduko w'amazi n'umuvuduko wo hejuru ukora ku kirere. Ikirere kiguma gihagaze neza ku burebure bujyanye n'umuvuduko w'amazi: umuvuduko mwinshi w'amazi uzamura ikirere hejuru, mu gihe umuvuduko muto w'amazi utuma kigabanuka. Igipimo cyagenwe inyuma y'umuyoboro gituma abakoresha basoma umuvuduko w'amazi bitewe n'aho ikirere giherereye.
Kimwe mu byiza by’ibipimo bya rotameters ni uburyo bworoshye kandi buhendutse. Bitandukanye na electromagnetic flowmeters zisaba ingufu n’ibikoresho by’ikoranabuhanga bigoye, cyangwa electromagnetic flowmeters zifite sisitemu zikomeye zo gupima, rotameters nta bice zigendamo uretse slab. Iyi miterere ntoya ituma ikiguzi cyo gukora kigabanuka, bigatuma ziba amahitamo meza yo gukoresha mu buryo buciriritse—nk’igerageza rya laboratwari, gupima imiti mu buryo buciriritse, cyangwa gutunganya amazi make. Byongeye kandi, kutagira electron bivuze ko zishobora gukorera ahantu hatandukanye cyangwa hakeye amashanyarazi, inyungu ikomeye ku mirimo yo kugenzura ibidukikije nko gupima ibidukikije cyangwa sisitemu zo gutanga amazi mu cyaro.
Rotameters nazo zirabagirana mu buryo bworoshye bwo kuzishyiraho no kuzikoresha. Ntabwo zisaba imiyoboro igororotse (ibisanzwe bisabwa kuri turbine cyangwa ultrasonic flowmeters) kandi zishobora gushyirwaho mu buryo buhagaze nta gushyiraho cyane—ni byiza ku myanya minini cyangwa sisitemu zisanzwe aho kongera gushyiramo ibintu bigoranye. Gusoma amashusho bitaziguye bikuraho gukenera kwerekana amakuru mu buryo bwa digitale cyangwa kwandika amakuru, bigatuma abakoresha bareba uko amazi agenda anyura mu kirere. Ku porogaramu zisaba kugenzura buri gihe, rotameters nyinshi zishobora gushyirwaho ibikoresho byihariye nka sensors za magnetic cyangwa optical detectors kugira ngo zihindure aho float iri mo ikimenyetso cy'amashanyarazi (urugero, 4-20mA) kugira ngo zihuzwe na sisitemu zo kugenzura—bivanze no koroshya ubushobozi bw'ibanze bwo kwikora.
Indi mbaraga z'ingenzi ni uburyo zikoresha mu gupima ibintu bitandukanye mu bwoko bw'amazi. Ibikoresho bya Rotameter bishobora gupima ibintu byombi bivanze n'amazi (urugero: amazi, amavuta, imiti) na gaze (urugero: umwuka, azote, gaze karemano), bifite imiterere ijyanye n'imiterere yihariye y'ibice by'amazi. Urugero, ibikoresho bya rotameter by'ibirahure bikoreshwa mu bintu bidafite ubushyuhe bwinshi, nk'amazi cyangwa umwuka, bitanga ubwisanzure kugira ngo byoroshye kubona ibintu bihindagurika. Ibikoresho bya rotameter by'ibyuma (ubusanzwe bikozwe mu cyuma kitagira umuvuduko cyangwa umuringa) byagenewe ibintu bihindura ubushyuhe bwinshi, gaze zifite umuvuduko mwinshi, cyangwa ibikoresho bikoresha ubushyuhe bwinshi—nk'ibipimo by'ibikoresho by'inganda cyangwa umwuka ushyushye. Ibikoresho bya rotameter bishobora kandi guhindurwa: ibirere bya PTFE kugira ngo birwane n'imiti, ibirere bya rotameter kugira ngo bikoreshwe mu muvuduko mwinshi, cyangwa ibirere bya ceramic kugira ngo bikoreshwe mu mazi ahindagurika—bigamije kubahiriza ibikenewe mu nganda zitandukanye.
Mu bikorwa bifatika, rotameters zigaragaza agaciro kazo mu nganda. Muri laboratoires, zikoreshwa mu kugenzura urujya n'uruza rw'imyuka itwara amashanyarazi muri chromatography ya gaze cyangwa kugenzura kongeramo reagents mu bushakashatsi bwa shimi—aho gupima neza kandi ku rugero ruto ari ngombwa. Mu nganda, zigenzura urujya n'uruza rw'amavuta yo kwisiga mu mashini cyangwa amazi akonjesha mu bikoresho, zikarinda kwangirika kw'ibikoresho bitewe no gusiga munsi y'amazi cyangwa gukabya. Mu buhanga mu by'ibidukikije, zipima urujya n'uruza rw'imiti mu nganda zitunganya amazi yanduye (urugero: imiti igabanya ubukana cyangwa imiti yica udukoko) cyangwa urujya n'uruza rw'umwuka mu nganda zigenzura imyuka ihumanya—bishyigikira iyubahirizwa ry'amahame ngengamikorere.
Nubwo rotameter zifite imbogamizi—ntizivuga neza ku muvuduko mwinshi w’amazi (ubusanzwe zirenga 100 m³/h ku binyabutabire) kandi zikaba zifite ingaruka ku mpinduka mu bucucike bw’amazi cyangwa ubucucike—imbaraga zazo ziruta cyane izi mbogamizi mu mikoreshereze yazo. Ku muvuduko muto kugeza ku muvuduko uri hagati, aho uburyo bworoshye, ikiguzi, no kwizerwa ari byo byihutirwa, rotameter ntizigereranywa. Iterambere rya none, nka rotameters zigezweho zifite uburebure bwa digitale na wireless connectivity, zarushijeho kwagura uburyo bwazo, bituma zigenzurwa kure ariko zigakomeza inyungu zazo z’ingenzi.
Mu gusoza, rotameters ni igihamya cy'imbaraga z'ubuhanga bworoshye. Zitanga uburyo bwo gupima amazi buri gihe kandi bwizewe nta mbogamizi cyangwa ikiguzi cy'ikoranabuhanga rigezweho, bigatuma ziba igikoresho cy'ingenzi muri laboratwari, mu nganda no mu bikorwa byo mu murima ku isi yose. Byaba bikoreshwa mu kugenzura ibintu mu buryo bw'ibanze cyangwa bihujwe na sisitemu zikora, rotameters zikomeje kugira uruhare runini mu kugenzura neza, mu mutekano, kandi bikurikiza amategeko mu nganda zose.
