Nkigikoresho cyingenzi cyo gupima ikoreshwa ryamazi, imikorere ya metero yamazi ifitanye isano rya hafi n’ibikorwa byayo. Ubwoko butandukanye bwa metero zamazi buratandukanye cyane mubihe byubushakashatsi, ibisabwa byubwiza bwamazi, hamwe n’imihindagurikire y’ikirere. Guhitamo metero yamazi meza kubidukikije ni ngombwa kugirango harebwe ibipimo bifatika hamwe nigihe cyo gukoresha ibikoresho.
Ukurikije ibidukikije byashizweho, metero zamazi zirashobora gushyirwa mubyiciro nkubwoko butose - cyangwa bwumye -. Ubwoko bw'amazi yatose -, uburyo bwo gupima bukaba buhuye neza n’amazi atemba, bikwiranye n’ibidukikije bisanzwe bifite ubushyuhe busanzwe hamwe n’amazi meza - yangirika, nkamazu yo guturamo n’amazu y’ubucuruzi. Ibi bidukikije biragaragaza amazi meza, ubushyuhe buri hagati ya dogere 5 na dogere 40, hamwe no kutagira umwanda uhambaye cyangwa ibice byangiza imiti, bigatuma igihe kirekire - gikora cyizewe cyimikorere yibikoresho bya metero zamazi atose-. Kuma - ubwoko bwa metero y'amazi, kurundi ruhande, uburyo bwabo bwo kubara bwitandukanije n’amazi kandi bwohereza ibyasomwe hakoreshejwe imiyoboro ya magneti. Birakwiriye cyane kubice bifite amazi mabi cyangwa ibyago byo gukonja mubushyuhe buke, nkamariba ya metero yo hanze mu turere dukonje two mu majyaruguru cyangwa ibidukikije bigoye by’amazi meza y’ibihingwa nganda bifite amavuta, ingese, n’ibindi byanduza. Igishushanyo cyabo gifunze birinda neza kwangiza urubura hamwe n’umwanda kwangirika kuri konti. Ubwiza bw’amazi ni ikindi kintu cyingenzi kigira ingaruka kuri metero yamazi. Mugihe cyamazi meza asukuye, metero zisanzwe zamazi zirashobora gukora neza mumyaka mirongo. Ariko, niba amazi arimo imyanda myinshi hamwe nubutaka bwahagaritswe (nkamazi yubutaka adahungabanijwe neza), cyangwa niba pH idasanzwe (hejuru cyane cyangwa hasi cyane), ibi birashobora kwihutisha kwambara kwimitsi no kubora ibice byimbere. Kuri ibi bintu, nibyiza gushyira imbere metero zamazi azenguruka hamwe no kwihanganira umwanda wanduye cyangwa gushiraho pre - muyunguruzi kugirango wongere igihe cyigikoresho.
Imihindagurikire y’ibihe nayo ni ngombwa. Mu turere twinshi - ubushyuhe (nk'ahantu hashyuha hashyuha ubushyuhe burenga dogere 40 - kuzenguruka), hagomba gutekerezwa kurwanya ubushyuhe bwibikoresho bya metero y'amazi hagamijwe gukumira ihindagurika ryibigize plastike no kunanirwa kashe. Ibidukikije biri hejuru - (nko mu turere two ku nkombe) bisaba ubuhehere - byerekana ko wirinda ingese z’ibice by’umuzunguruko (kuri metero y’amazi meza) cyangwa gari ya moshi bitewe n’ubushuhe. Byongeye kandi, mubihe bimwe byihariye, nka sisitemu yo gutanga amazi ya kabiri mumazu maremare -, aho umuvuduko wamazi uhindagurika cyane, hasabwa metero yamazi ifite kwihanganira umuvuduko mwinshi kugirango isuzumwe neza.
Muri make, uburinganire bwa metero yamazi busaba isuzumabumenyi ryuzuye ryimiterere yimiterere, ibiranga ubwiza bwamazi, nibihe byikirere. Gusa muguhuza neza nibikenewe mubidukikije birashobora gukoreshwa neza mugupima metero zamazi gukoreshwa neza kandi inkunga yizewe yatanzwe mugucunga umutungo wamazi.
