Iyo ukurikirana ikoreshwa ry’imiyoboro y’amazi yanduye, isuku y’imyanda cyangwa imishinga yo kuhira, guhitamo icyuma gipima amazi afunguye neza bigena neza uburyo ibipimo bipimwa, kubahiriza amategeko n’inshingano z’igihe kirekire zo kubungabunga. Injeniyeri nyinshi zirengagiza ingingo imwe y’ingenzi: nta gipimo cy’amazi afunguye gikoreshwa neza kuri buri hantu. Imikorere yacyo iterwa cyane no kuba gihuye n’imiterere y’amazi yashyizweho cyangwa icyuma gipima amazi. Ikibazo cy’ingenzi rero kirahari: ni ikihe gipimo cy’amazi afunguye gihuye n’imiterere y’icyuma gipima amazi afunguye cyangwa icyuma gipima amazi afunguye?
Inzu zo gupima amazi n'ibice by'amazi ni ibikoresho by'ibanze bipima bigamije guhuza amazi n'umuvuduko wayo. Inzu zo gupima amazi, harimo izu ndende za V notch na mpandeshatu, zitera imbogamizi mu muyoboro, bigatuma amazi asuka ku mpande zigenzurwa. Inzu zo gupima amazi zitanga ubushobozi bwo kumenya neza imiterere y'amazi make, zikoreshwa cyane mu nzira nto zo kuvoma amazi yanduye no mu buryo bwo kuyasukura muri laboratwari. Nyamara, izi nzu zo gupima amazi zikora ibidendezi byo mu mazi aho imyanda, ibitaka n'imyanda ireremba byoroshye kwirundanya. Gusukura kenshi biba itegeko, bitabaye ibyo, ibisigazwa bizahindura imiterere y'amazi kandi bigatanga amakuru y'amazi adasobanutse.
Flume, nka Parshall flume ikunzwe ku isi yose, igabanya ibice by'imiyoboro kugira ngo yihutishe amazi kugera ku muvuduko ukomeye mu gice cy'umuhogo. Kubera umuvuduko w'amazi wihuta, flume zifite ubushobozi bwo kwisukura kandi zirwanya kwiyubaka kw'imyanda. Ibyo bituma ziba amahitamo meza yo gukoresha imyanda mibi, imyanda iva mu nganda n'umucanga utwara amazi cyangwa uduce duto. Ugereranyije n'inkuta, flume zitera igihombo cyo hasi kandi zihanganira amazi agwa mu mazi, nyamara zisaba kubaka neza no gushyiraho neza kugira ngo zimenye neza.
Ibipimo bigezweho bya ultrasonic open channel metre bipima ingano y'amazi binyuze mu gupima ubujyakuzimu bw'amazi mu gihe nyacyo no gukoresha formula za hydraulic zateguwe mbere ku byuma bipima amashanyarazi cyangwa flume. Ariko, si ibikoresho byose bitanga amakuru bishyigikira isomero ryuzuye ry'ibipimo bya flume. Ibikoresho bimwe na bimwe bihendutse bitanga gusa imiterere y'imiyoboro mike. Iyo uhuje icyuma kidakoresheje ibipimo byubatswe neza kuri Parshall flume cyangwa threethrial weir, uzabona umusaruro uhoraho ariko utari wo rwose, nubwo imiterere y'amazi isa n'aho isanzwe. Iki ni ikibazo gikunze kugaragara mu kugura ibikoresho byo mu murima.
Uretse guhuza imiterere y'aho amazi akorera, ugomba gusuzuma imiterere nyayo y'aho akorera. Ku mazi meza asohoka afite ingano ntoya, icyuma gipima amazi cyagenewe inkuta za V gishobora gutanga ibisubizo bihamye kandi bihendutse byo gupima. Ku mwanda w'amazi mabi yo mu mujyi ufite imyanda myinshi, hitamo icyuma gipima amazi gihuye neza n'amakuru ya Parshall flume, kandi wemeze ko imikorere yo kurwanya umwuka, amazi asuka n'amazi ahindagurika ku butaka aho akorera ikoreshwa. Imikorere y'itumanaho nayo ikwiye kwitabwaho. Ibisohoka bya M-Bus, Modbus-RTU cyangwa HART byemerera kohereza amakuru kure kugira ngo hamenyekane niba ibidukikije bikurikiza amategeko, bigakuraho amakosa yo kwandika intoki.
Ibisabwa mu gushyiraho nabyo ntibishobora kwirengagizwa. Inzu zombi zombi n'iz'amashanyarazi zikenera ibice bihagije by'imiyoboro yo hejuru n'iyo hepfo kugira ngo zihamye imiterere y'amazi atemba. Ndetse n'imashini ipima amazi ifunguye neza cyane izahura n'ikibazo cyo kunyura mu buryo buboneye niba imirimo y'ubwubatsi itujuje ibisabwa. Abatanga ibikoresho bizerwa batanga inyandiko zuzuye za tekiniki, bayobora injeniyeri mu gushyiramo sensor, uburebure buke bw'imiyoboro igororotse n'uburyo bwo kuyipima. Gufasha mu gihe kiri kure bigabanya igihe cyo kudakora ku nyubako z'umujyi n'inganda.
Impamyabushobozi ikwiye kandi kwitabwaho ku mishinga mpuzamahanga. Kwemeza imiterere y'ikirere bireba ko amakuru apimwe y'imigendekere yemewe muri raporo zemewe z'ibidukikije. Irinde guhitamo metero zihendutse zitemewe, kuko kwanga kwakira umushinga bizatera igihombo kinini kuruta kuzigama ibikoresho bya mbere.
Muri make, guhuza icyuma gipima amazi gifunguye n'imiterere y'icyuma gisanzwe cyangwa icyuma gipima amazi ni ingenzi mu gupima amazi neza. Emeza imiterere y'amazi yubatswemo, imiterere y'amazi, imbogamizi zo gushyiraho n'aho itumanaho rikenewe mbere yo kugura. Niba usangiye amakuru arambuye arimo ubwoko bw'icyuma gipima amazi cyangwa icyuma gipima amazi, ingano y'icyuma, imiterere y'icyuma gipima amazi n'aho amazi anyura, abahanga mu bya tekiniki bashobora gutanga igisubizo cy'icyuma gipima amazi gifunguye gikwiye cyane ku ikoreshwa ry'icyuma cyawe cyihariye.
