Mu gupima umuvuduko w’amazi mu nganda, aho ukuri, ubwizerwe, no guhuza n’amazi agoye bidashoboka kuganirwaho, ibipimo by’umuvuduko w’amazi bigaragarira nk'igisubizo cyizewe. Bitandukanye n’ibipimo by’umuvuduko w’amazi bikoresha ikoranabuhanga rya ultrasonic cyangwa electromagnetic birusha ibindi mu bikoresho biyobora cyangwa bitakoresha amashanyarazi, ibipimo by’umuvuduko w’amazi bikoreshwa mu buryo bworoshye mu gukoresha ibinyobwa bivanze—kuva ku mavuta yo kwisiga n’amazi akoreshwa mu mazi kugeza kuri sirope, amarangi, n’ibindi bikoresho by’imiti. Imiterere yabyo ituma bipima neza kandi neza nubwo byaba biri ku muvuduko muto w’amazi, bigatuma biba ngombwa cyane mu nganda zitandukanye kuva ku nganda zikora imodoka kugeza ku zitunganya ibiribwa.
Ishingiro ry'imikorere y'icyuma gipima ubwikorezi bw'amashanyarazi ni ihame ryacyo ryo kwimura amazi (PD), uburyo bworoshye ariko bufite akamaro bubara ingano y'amazi. Imbere y'icyuma gipima amashanyarazi igizwe na vitesi ebyiri cyangwa nyinshi zifatanye (zikunze gukorwa mu byuma bitarangwamo ibyuma, PTFE, cyangwa pulasitiki ikomeye) zibikwa mu cyumba gikozwe mu buryo bunoze. Uko amazi yinjira mu cyumba, yuzuza icyuho kiri hagati y'amenyo y'icyuma, bigatuma vitesi zizenguruka. Buri kuzenguruka kw'ibitesi bisimbura ingano ihoraho izwi y'amazi—izwi nka "igipimo cy'imashini"—ihita yoherezwa kuri sensor (mekanike cyangwa electronic) ihindura ingendo yo kuzenguruka mu kimenyetso gipimirwa. Iki kimenyetso gitunganywa kugira ngo kibare ingano yose cyangwa umuvuduko w'amazi ako kanya, hishingikirijwe ku bintu byo hanze nko gutwara amazi cyangwa imiterere y'amazi.
Kimwe mu byiza bizwi cyane by'ibipimo by'amashanyarazi ni ukubera ko ari ingirakamaro cyane, ndetse no mu bikorwa bito cyane kandi bidakoresha amazi menshi. Ibipimo by'amashanyarazi byinshi byo mu rwego rw'inganda bigira ubwiza buri hagati ya ± 0.1% na ± 0.5% by'agaciro gapimwe, biruta ibindi bipimo by'amashanyarazi byinshi mu bihe aho ubwiza ari ingenzi cyane. Urugero, mu miyoboro y'imodoka, ibipimo by'amashanyarazi bikoreshwa mu gupima ingano nyayo y'amavuta yo kwisiga ashyirwa mu bice bya moteri—amavuta make cyane ashobora kwangirika vuba, mu gihe menshi cyane atakaza umutungo kandi ashobora gutera ubushyuhe bwinshi. Ubushobozi bw'ibipimo bwo kugumana ubwiza mu rugero runini rw'ubwiza (kuva kuri 1 cP kugeza kuri 1.000.000 cP cyangwa irenga) bituma biba byiza kuri iyo mirimo, kuko impinduka z'ubwiza zigira ingaruka nke ku kwimura kw'ibipimo.
Indi nyungu y'ingenzi ni imiterere yazo ikomeye n'ibisabwa bike mu kubungabunga. Ibikoresho bifatanye n'icyumba byubatswe mu bikoresho biramba birwanya ingese, kwangirika no kwangirika kwa shimi—ni ingenzi mu gucunga amazi ashyushye nk'ibinyabutabire byo mu nganda cyangwa sirupe zo mu rwego rw'ibiribwa. Bitandukanye na turbine flowmeters, zifite ibice byoroshye bigenda bisaza, turbine flowmeters zifite imiterere yoroshye, ntoya kandi ifite ibice bike bishobora kwangirika. Uku kuramba bivuze ko ubuzima bumara igihe kirekire (akenshi imyaka 5-10 iyo ikoreshejwe neza) kandi ikagabanya igihe cyo kuyitunganya. Byongeye kandi, turbine nyinshi zigezweho zikoresha imiterere idafunze cyangwa ihuza ry'amashanyarazi, bikuraho ibyago byo gusohoka kw'amazi—akamaro k'ingenzi ku bikorwa birimo amazi y'uburozi cyangwa afite agaciro gakomeye.
Ibipimo by'amashanyarazi kandi ni byiza cyane mu buryo butandukanye mu nganda, bihuza n'ubwoko butandukanye bw'amazi n'imiterere y'imikorere. Mu rwego rw'ibiribwa n'ibinyobwa, bikoreshwa mu gupima urujya n'uruza rw'ibintu bito cyane nka shokora, ubuki, cyangwa inyanya, hamwe n'ibikoresho byo mu rwego rw'ibiribwa (nk'icyuma kitagira umugese cya 316L na elastomer zemewe na FDA) bigamije kubahiriza amahame y'umutekano. Mu nganda zikora peteroli na gaze, bakurikirana urujya n'uruza rw'amazi ya hydraulic mu bikoresho byo gucukura no mu byuma bisiga amavuta mu byuma bikonjesha imiyoboro, aho kurwanya umuvuduko mwinshi (kugeza kuri 10.000 psi cyangwa irenga) n'ubushyuhe (kuva kuri -40°C kugeza kuri 200°C) ari ingenzi cyane. Ndetse no mu nganda zikora imiti, ibipimo by'amashanyarazi bigira uruhare mu gupima neza imiti itoshye n'inyongera, aho ubwiza n'ubuziranenge ari ingenzi cyane.
Guhuza na sisitemu zo kugenzura inganda ni ubundi buryo bukomeye bw'ibipimo by'amashanyarazi bigezweho. Moderi nyinshi ziza zifite ibikoresho bitanga umusaruro mu buryo bwa digitale (nka RS485/Modbus, HART, cyangwa ibimenyetso bya pulse) cyangwa ibikoresho bya analog (4–20mA), bitanga uburyo bwo guhuza neza na sisitemu za SCADA, ibyuma bitanga amakuru, cyangwa PLC. Ibi bituma habaho gukurikirana mu buryo butaziguye umuvuduko w'amazi mu gihe nyacyo, gupima kure, no kugenzura imikorere mu buryo bwikora—urugero, guhindura urujya n'uruza rw'irangi mu ruganda rukora kugira ngo harebwe ko ubunini bw'ibara buhoraho. Moderi zimwe na zimwe zigezweho zirimo n'ibikoresho byo gusuzuma, nko kumenya uko ibikoresho byangiritse cyangwa gutanga amakuru ku byanduza amazi, bifasha ababikora gukemura ibibazo mbere yuko bibatera gutakaza amafaranga menshi.
Nubwo bifite ibyiza byinshi, ibipimo by'imikoreshereze y'ibikoresho ntibikoreshwa ku isi hose. Ntibikwiriye cyane ku mazi arimo uduce duto (dushobora gufunga ibyuma) cyangwa amazi ahindagurika cyane (ashobora gutera gucika). Ariko, ku mazi menshi akomeye, asukuye, cyangwa yanduye gato, aracyari amahitamo meza. Ubushobozi bwabyo bwo guhuza ubuhanga bwo hejuru, kuramba, no gukoresha ibintu byinshi mu buryo butandukanye butuma biba inkingi yo gupima amazi mu nganda, bishyigikira imikorere myiza, kuzigama ikiguzi, no kubahiriza amategeko mu bikorwa byinshi bitandukanye.
Muri make, ibipimo by'amashanyarazi birenga ibikoresho byo gupima gusa—ni ibintu by'ingenzi bishimangira ubuziranenge n'ubwizerwe mu nganda aho kugenzura amazi bigira ingaruka ku ireme ry'ibicuruzwa n'umutekano w'imikorere. Uko ikoranabuhanga ritera imbere, imiterere yabyo ikomeza gutera imbere, hamwe n'iterambere mu bikoresho, ikoranabuhanga rya sensor, no guhuza ibintu byongera imikorere yabyo. Ku bigo bishaka igisubizo cyo gupima amazi gishobora guhangana n'amazi afite umuvuduko muke n'amazi make mu buryo buboneye, iki gipimo cy'amashanyarazi gikomeje kuba amahitamo adatsindwa.
