Mu rwego rwo gupima amazi akoreshwa mu miyoboro ifunguye, ibipimo ngenderwaho by’amazi bikoreshwa mu miyoboro y’amazi bimaze igihe kinini byemewe nk'igisubizo cyizewe kandi gihendutse, gikoreshwa cyane mu nzego z’imijyi, inganda, n’igenzura ry’ibidukikije. Birangwa n'imiterere yabyo yoroshye, imikorere ihamye, no kubahiriza amahame mpuzamahanga yo gupima, ibi bipimo bigira uruhare runini mu gupima amazi n'ibindi bintu biva mu miyoboro ifunguye nk'imigezi, imiyoboro y'amazi, n'imiyoboro y'amazi. Iyi nkuru irasuzuma ibyiza by'ingenzi, ikoreshwa ritandukanye, ibipimo ngenderwaho by'ingenzi byo guhitamo, n'ibikenewe mu kubungabunga ibipimo ngenderwaho by'amazi bikoreshwa mu miyoboro, bigaragaza uruhare rwabyo rudasimburwa mu gucunga umutungo kamere w'amazi no kugenzura ibikorwa by'inganda.
Kimwe mu byiza by'ingenzi by'ibipimo ngenderwaho by'amazi biri mu gukurikiza imiterere isanzwe n'uburyo bwo gupima amazi akuze. Bitandukanye n'ibikoresho bipima amazi byihariye, amazi asanzwe—nk'amazi ya Parshall, amazi ya Venturi, n'imiyoboro y'uruziga—akurikiza amabwiriza yemewe ku rwego mpuzamahanga (urugero, amahame ya ISO, ASTM), atuma habaho ibisubizo bihamye kandi bisa mu buryo butandukanye. Ubu buryo bwo gupima amazi bworoshya gupima, bugabanya amakosa yo gupima, kandi bukoroshya iyubahirizwa ry'amategeko, bigatuma aba amahitamo meza ku bihe bisaba amakuru yemewe y'amazi, nko gusuzuma ingaruka ku bidukikije n'imishinga yo gutanga umutungo w'amazi. Byongeye kandi, imiterere yabo yoroshye ya mashini, idafite ibice bigenda, igabanya ibyago byo kwangirika, kuziba, cyangwa kwangirika kwa mashini, bigatuma habaho imikorere ihamye igihe kirekire ndetse no mu bidukikije bikomeye birimo amazi yuzuyemo imyanda cyangwa imyanda.
Uburyo bwo gukoresha ibipimo ngenderwaho by’amazi akoreshwa mu miyoboro y’amazi ni bwinshi, bireba inzego z’umujyi, inganda, ubuhinzi, n’ibidukikije. Mu micungire y’amazi mu miyoboro y’amazi, bikoreshwa cyane mu nganda zitunganya amazi y’imyanda kugira ngo bigenzure amazi atemba n’asohoka, bitanga amakuru y’ingenzi yo kunoza uburyo bwo kuyatunganya no kwemeza ko yubahirizwa. Urugero, amafuru ya Parshall, afite ubuhanga bwo gupima amazi neza haba mu bihe by’amazi akoreshwa mu buryo buciriritse ndetse no mu bihe by’amazi akoreshwa mu buryo bukabije, akunze gushyirwa mu miyoboro y’amazi y’imyanda kugira ngo akurikirane uburyo bwo kuyatunganya no gucunga neza umutungo w’amazi. Mu miyoboro y’amazi yo kuhira mu buhinzi, amafuru asanzwe agira uruhare runini mu gupima ikwirakwizwa ry’amazi, gufasha abahinzi kunoza gahunda yo kuhira, kugabanya imyanda y’amazi, no kunoza uburyo amazi akoreshwa neza—cyane cyane mu turere tw’ubutayu n’utwo mu turere tw’ubutayu.
Mu nganda, ibipimo ngenderwaho by’amazi akoreshwa mu kugenzura amazi yanduye yo mu nganda, amazi akonje, no gutunganya imyanda. Inganda nk'ubucukuzi bw'amabuye y'agaciro, inganda zikora impapuro, n'izitunganya ibiribwa, zikora amazi menshi yanduye arimo uduce duto cyangwa ibintu bito, zungukira ku kudakomera kw'amazi akoreshwa mu mazi no kudakenera kubungabunga ibidukikije. Mu kugenzura ibidukikije, ibi bipimo ngenderwaho bikoreshwa mu bibaya by'imigezi, ibiyaga, n'uturere two ku nkombe kugira ngo bipime umuvuduko w'amazi yo ku butaka, bishyigikire ubushakashatsi ku mazi, kumenya imyuzure, no gusuzuma ubuziranenge bw'amazi. Urugero, imiyoboro y'amazi ikunze gushyirwa mu migezi mito kugira ngo ikusanye amakuru y'amazi akoreshwa mu gihe kirekire, ifashe mu kurinda urusobe rw'ibinyabuzima byo mu mazi no mu gucunga ibiza biterwa n'amazi.
Guhitamo icyuma gipima ubwikorezi bw'amazi gikwiye bisaba gusuzuma neza ibintu byinshi by'ingenzi kugira ngo hamenyekane imikorere myiza. Ubwa mbere, ubwoko bw'amazi bugomba guhuzwa n'imiterere y'umuyoboro n'urwego rw'amazi anyuramo. Amashanyarazi ya Parshall ni meza ku muvuduko munini w'amazi n'imiyoboro migari, mu gihe amashanyarazi ya Venturi akwiriye gukoreshwa ahantu hafite umwanya muto n'ibisabwa ku buryo bunonosoye. Ku rundi ruhande, inkingi z'amazi zifite impande enye zikunze gukoreshwa ku muvuduko muto kugeza ku muvuduko uri hagati mu miyoboro mito. Icya kabiri, ingano y'amazi igomba gutoranywa hashingiwe ku muvuduko ntarengwa n'umuvuduko muto witezwe kugira ngo amazi agume mu rugero rwiza rw'amazi anyuramo, hirindwa amakosa aterwa no kugabanuka kw'amazi cyangwa kurenga umuvuduko. Byongeye kandi, ahantu ho gushyiraho hagomba kwitabwaho—amashanyarazi ashyirwa hanze ashobora gusaba ibikoresho birwanya ingese (nk'icyuma kitagira umugese cyangwa fiberglass) kugira ngo bihangane n'ihindagurika ry'ikirere n'ingese za shimi zituruka ku buryo bupimwe.
Kubungabunga neza ni ingenzi kugira ngo ibipimo ngenderwaho by’amazi bisanzwe bikoreshwa mu byuma bipima amazi bikomeze kuba inyangamugayo kandi bihamye mu gihe kirekire. Hagomba gukorwa igenzura rihoraho kugira ngo hakurweho imyanda, imyanda, n’ibimera byo mu mazi bishobora kwirundanya muri ibyo bikoresho, kuko bishobora kwangiza imiterere y’amazi kandi bigagira ingaruka ku bipimo. Umuhogo w’amazi, inkuta, n’agasongero k’ubutaka bigomba kugenzurwa niba nta byangiritse, cyangwa ko nta byangiritse, kandi inenge iyo ari yo yose igomba gusanwa vuba. Gupima, hakurikijwe amabwiriza y’uruganda n’amahame ajyanye nabyo, nabyo ni ingenzi—gupima buri gihe byemeza ko ibyo bikoresho bipima amazi bikomeza gutanga amakuru nyayo, cyane cyane nyuma yo gukoreshwa igihe kirekire cyangwa impinduka zikomeye mu miterere y’ibikoresho bipima amazi.
Mu gusoza, ibipimo ngenderwaho by’amazi bikoreshwa mu gupima amazi bigaragarira ku buryo bufatika kandi bwizewe mu gupima amazi mu buryo bufunguye, bitanga imikorere isanzwe, uburyo bwo kuyakoresha mu buryo bwagutse, kandi bikaba ari ngombwa kuyitaho. Uruhare rwabyo mu gucunga umutungo w’amazi, kugenzura ibikorwa by’inganda, no gukurikirana ibidukikije ni ingenzi cyane, bifasha mu gukoresha amazi neza, kubahiriza amategeko, no kurengera ibidukikije. Uko isi yose yita ku mutekano w’amazi n’iterambere rirambye bigenda byiyongera, ibipimo ngenderwaho by’amazi bizakomeza kuba inkingi y’ingenzi mu ikoranabuhanga ryo gupima amazi, bihuze n’ibyo inganda zikeneye mu gihe bikomeza kugira ibyiza byabyo by’ingenzi byo koroshya, kwizerwa no gukora neza.
