Igendanwa kandi ntiyinjirira; ikwiriye abakoresha transducers bashyiramo ibyuma bifunga.
Bihuta kurusha gupima uruganda (isaha 1-2 kuri metero imwe).
Imbibi
Ubunyangamugayo buri hasi ugereranije n'uburyo bwo mu ruganda (ubusanzwe ± 1–2% yo kwihanganira amakosa).
Ntibikwiriye uburyo bwo gutembera cyane cyangwa bukoresha umuvuduko mwinshi.
b. Kugereranya Igipimo cy'Icyitegererezo (Gushyiraho Igipimo Kijyanye nacyo)
Intego
Igenzura ry'ubunyangamugayo ry'igihe kirekire mu bikorwa by'ingenzi.
Uburyo bwo gukora
Shyiramo icyuma gipima ubuziranenge bw'ikirenga (urugero: Coriolis, turbine) gifatanye n'icyuma gipima ubuziranenge bw'ikirere.
Gereranya buri gihe ibipimo biri hagati ya metero ebyiri uko igihe kigenda gihita.
Hindura ibipimo by'icyuma gipima ikoranabuhanga (urugero: kwiyongera, igihe cyo gutwara) niba ibinyuranyo birengeje ubushobozi bwo kwihanganira (urugero: >0.5% by'ubunini bwose).
Ibyiza
Itanga igenzura ry'igihe nyacyo nta kubangamira urujya n'uruza rw'amakuru.
Bikwiriye koherezwa mu gihe cyo gucungirwa cyangwa gusaba kwishyuza.
Imbibi
Ikiguzi kinini bitewe n'ibikoresho by'inyongera n'ishyirwaho ryabyo.
Bisaba ko imiyoboro igororotse bihagije kuri metero zombi.
c. Gupima ubwinshi bw'amazi hakoreshejwe uburyo bwa Computational Fluid Dynamics (CFD)
Intego
Emeza imikorere mu miterere y’amazi igoye (urugero, nyuma yo kugonga imiyoboro).
Uburyo bwo gukora
Koresha porogaramu ya CFD kugira ngo ugaragaze aho amazi anyura ukoresheje ikoranabuhanga ripima amashanyarazi.
Ibipimo by'inyongera nk'umurambararo w'umuyoboro, umuvuduko w'amazi, n'imiterere y'umuvuduko w'amazi.
Gereranya ikwirakwira ry'umuraba wa ultrasound ryateganijwe muri iyo moderi n'ibipimo nyabyo by'umubare w'umubare w'amazi.
Ibyiza
Ntibibangamira; nta mpinduka zikenewe ku mubiri.
Bifasha kumenya amakosa ajyanye no gushyiramo (urugero, intera idakwiye hagati ya transducer).
Imbibi
Bisaba ubuhanga mu bijyanye no gushushanya CFD.
Ubunyangamugayo bushingiye ku bunyangamugayo bw'ibipimo by'ibyinjira.
3. Kwisuzuma (Kwifashisha mu gusuzuma indwara)
Intego
Gukurikirana ubuzima mu buryo bwihuse no guhindura ibintu bito.
Uburyo bwo gukora
Igenzura ry'igihe cyo gutwara abantu mu nzira:
Icyo gipimo gipima buri gihe igihe cy'urugendo rw'umuraba wa ultrasound.
Gutandukana n'ibanze (urugero, bitewe n'ihindagurika ry'umuyoboro w'amashanyarazi cyangwa imiyoboro y'amazi) bitera amatangazo.
Isesengura ry'Ikigereranyo cy'Urusaku ku Gipimo cy'Ibimenyetso (SNR):
Igenzura imbaraga z'ibimenyetso bya ultrasound byakiriwe.
SNR nkeya ishobora kugaragaza kwangirika kwa transducer cyangwa kwanduzwa n'amazi.
Kwishyura ubushyuhe:
Ibipimo by'ubushyuhe bw'imbere bihindura umuvuduko w'umuraba, bigagabanya guhindagurika kw'amazi.
Ibyiza
Nta bikoresho byo hanze bikenewe; igenzura rihoraho.
Ihendutse ku buryo butari ingenzi cyane.
Imbibi
Ntibishobora gukosora amakosa akomeye yo gutembera (urugero, bitewe n'ibyangiritse bya transducer).
Bisaba ko habaho igenzura ry’uburyo bwo hanze buri gihe.
4. Gupima ubwoko bwihariye bwa Ultrasonic
a. Ibipimo by'igihe cyo gutwara abantu n'ibintu
Icyibandwaho cy'ingenzi: Gupima igihe cyo gutwara abantu ukurikije igipimo cy'amazi.
Intambwe zidasanzwe:
Hindura ingaruka z'ubushyuhe ku muvuduko w'umuraba (urugero, ukoresheje thermocouple iri mu muyoboro).
Genzura inguni y'imirasire ya ultrasonic (ubusanzwe 45°–60°) kugira ngo urebe neza ko umuvuduko w'ibice by'umuvuduko upimwe neza.
b. Ibipimo bya Doppler

Intambwe zidasanzwe:
Shyiraho ingano izwi y'uduce duto (urugero, uduce duto) kugira ngo wigane uko amazi agenda.
Hindura imiterere y'ingufu kugira ngo wongere uburyo bwo kugaragaza ibimenyetso biva ku bice bimwe na bimwe by'urukiramende.
5. Uburyo bwiza bwo gupima
- Igenzura rya mbere yo gupima
Menya neza ko umuyoboro wuzuyemo amazi (nta mifuka y'umwuka).
Genzura uburyo transducer ihagaze (ku bikoresho bifatanye) kandi usukure ubuso butose (ku bikoresho bifatanye).
- Amazi yo Gupima
Koresha amazi nyayo y'imikorere niba bishoboka; bitabaye ibyo, usimbuze imiterere isa n'iy'ijwi (urugero, amazi aho gukoresha amazi adakomeye).
- Kwandika amakuru
Inyandiko zipima uburyo bwo gupima (umuvuduko w'amazi, ubushyuhe, umuvuduko) n'impinduka zakozwe.
Gukurikirana ibipimo ngenderwaho (urugero: inomero z'icyemezo).
6. Inshuro zo Gupima Ubwinshi bw'Uburyo
Uburyo Isanzwe y'intera y'ubunyangamugayo Urwego rukwiriye
Gupima uruganda Rimwe mbere yo gukoresha ± 0.5% cyangwa birushijeho. Ibipimo bishya cyangwa ivugurura rikomeye.
Kalibarateri igendanwa amezi 6–24 ± 1–2% Igenzura ry'aho ibintu biherereye buri gihe
Kugereranya ibipimo ngenderwaho amezi 3–12 ± 0.5% Kwishyura by'ingenzi cyangwa kugenzura inzira
Kwigenzura mu buryo buhoraho ± 2–3% Gukurikirana ubuzima mu buryo bwihuse
Umwanzuro
Gupima ingano y'amazi hakoreshejwe ikoranabuhanga rigezweho bihuza amahame y'ibanze ashingiye ku ruganda n'uburyo bwo kugenzura imiterere y'ubutaka bujyanye n'ibikenewe mu ruganda. Ku bisabwa mu buryo bunonosoye cyane (urugero, kwimura ububiko), ibipimo ngenderwaho bihurirana cyangwa kongera gupima ingano y'ibikoresho mu ruganda ni ngombwa, mu gihe porogaramu zitari iz'ingenzi zishobora kwishingikiriza ku bikoresho bipima cyangwa kwisuzuma. Buri gihe huza uburyo bwo gusuzuma n'amabwiriza y'uruganda n'amahame ngenderwaho mu nganda (urugero, ISO, API) kugira ngo harebwe ko ibintu bikurikirana kandi bikubahirizwa.
