Mu rwego rwo gupima no kugenzura amazi y’inganda, ibipimo by’amazi akoreshwa mu nganda (EMFs) byigaragaje nk'ibikoresho by'ingenzi, bizwiho kuba byizewe, bifite imikorere myinshi, kandi bihura n'imimerere igoye y'imikorere. Bitandukanye n'ibikoresho bisanzwe bipima amazi akoreshwa mu nganda, ibi bikoresho bitanga inyungu zidasanzwe zibikoresha mu nganda zitandukanye, kuva ku gucunga amazi yo mu mujyi kugeza ku gutunganya imiti ikoreshwa mu nganda. Iyi nkuru irasuzuma inyungu z'ingenzi, ikoreshwa mu buryo bufatika, ibipimo by'ingenzi byo guhitamo, n'iterambere ry'abahanga mu iterambere ry'ibipimo by'amazi akoreshwa mu nganda, bigaragaza uruhare rwabyo rukomeye mu gutuma habaho imikorere myiza no kunoza imikorere.
Kimwe mu byiza by’ingenzi bya electromagnetic flowmeters ni imikorere yabyo idasanzwe yo gupima no guhuza ubwoko butandukanye bw’amazi. Ibi bikoresho bitanga ubuziranenge bwo hejuru, ubusanzwe biri hagati ya ± 0.2% na ± 0.5% by’agaciro kapimwe, kandi bigumana ubusugire hatitawe ku mpinduka mu bucucike bw’amazi, ubushyuhe, ubushyuhe, cyangwa igitutu. Igipimo cyabyo cyagutse cyo kugabanuka kw’amazi, akenshi kigera kuri 1000: 1, kibafasha gupima neza umuvuduko w’amazi mwinshi n’uwo hasi, bigatuma biba byiza gukoreshwa mu mihindagurikire ikomeye y’amazi, nko mu nganda zitunganya amazi yanduye cyangwa mu mikorere y’imiti. Byongeye kandi, kutagira ibice bibangamira amazi imbere bikuraho igihombo cy’umuvuduko, bigabanya ikoreshwa ry’ingufu, kandi bikarinda kuziba—akamaro k’ingenzi iyo upima amazi arimo uduce duto, fibre, cyangwa ibintu bito nk’urusenda, pulp, cyangwa imyanda.
Uburyo ibipimo by'amazi bikoreshwa mu gupima amazi hakoreshejwe amashanyarazi bireba inganda nyinshi, bigaragaza uburyo bikoresha imbaraga nyinshi kandi bikomeye. Mu micungire y'amazi mu nzego z'ibanze, EMF nini zikoreshwa cyane mu miyoboro y'amazi n'aho amazi asukurwa mu rwego rwo kugenzura ikwirakwizwa ry'amazi n'inzira yo kuyasukura, zigatanga amakuru y'ingenzi yo gukwirakwiza umutungo n'uko ibidukikije bikurikiza amategeko. Urugero, mu nganda zitunganya amazi yanduye, zipima neza amazi yanduye n'ayo mu mazi, bigatuma imiti itunganywa ikoreshwa neza kandi igakoreshwa neza mu gutunganya amazi. Mu nganda zitunganya peteroli n'imiti, EMF zifite imiyoboro irinda ingese n'ibikoresho bya electrode (nk'imiyoboro ya PTFE na electrode za Hastelloy) zifata amazi yangiza nka aside, alkali, n'imiti isukura, zigapima neza ahantu hari ubushyuhe bwinshi n'umuvuduko mwinshi.
Inganda zikora ibiribwa n'ibinyobwa, imiti n'ubucukuzi bw'amabuye y'agaciro nazo zungukira cyane ku bipimo by'amashanyarazi bikoreshwa mu gutunganya ibiribwa. Mu gutunganya ibiribwa, EMF zo mu rwego rw'isuku zifite ubuso bworoshye kandi bworoshye gusukura zujuje ibisabwa by'isuku, zipima neza ibinyobwa nk'imitobe y'imbuto, ibikomoka ku mata, n'amavuta yo kurya. Mu bucukuzi bw'amabuye y'agaciro, imiterere idashira ifite imitako ya keramike ipima neza ubutare burimo uduce duto two kwangirika, ikomeza gupima neza nubwo haba mu bihe bikomeye. Byongeye kandi, mu bigo bitanga amashanyarazi, ibi bipimo by'amazi bikurikirana amazi akonje mu nganda zitanga ingufu z'ubushyuhe n'imashini zitanga ingufu za kirimbuzi, bigira uruhare mu gutanga ingufu mu buryo bwizewe kandi bunoze.
Guhitamo icyuma gipima amashanyarazi gikwiye bisaba gusuzuma neza ibintu byinshi by'ingenzi kugira ngo habeho imikorere myiza. Icya mbere, imikorere y'amazi ni ngombwa cyane—EMFs akenshi zisaba imikorere y'amazi nibura 5 μS/cm, bigatuma zikoreshwa mu mazi ariko ntizikoreshwe mu mazi adakoresha amashanyarazi nk'amavuta cyangwa amazi meza. Icya kabiri, guhitamo ibikoresho ni ingenzi cyane: ibikoresho bigomba kuba bihuye n'imiterere y'ibinyabutabire by'amazi (urugero: rubber ku mazi rusange, PTFE ku aside ikomeye), mu gihe ibikoresho bya electrode (316L stainless steel, Hastelloy, cyangwa titanium) bigomba kurwanya ingese. Imiterere y'ibidukikije nayo igira ingaruka ku guhitamo, hamwe n'ibipimo byo kurinda nka IP67 cyangwa IP68 bisabwa ku bikorwa byo hanze cyangwa munsi y'amazi, hamwe n'ibyemezo bidashobora guturika (ATEX, IECEx) bikenewe ahantu hateje akaga hari imyuka cyangwa umwuka ushobora gushya.
Mu myaka ya vuba aha hagaragaye icyerekezo cyo kuvugurura ikoranabuhanga rya electromagnetic flowmeters, bitewe no guhuza ikoranabuhanga rya IoT na digitale. EMF zigezweho zifite uburyo bwo gutumanaho nka RS485, Ethernet, cyangwa 4G modules, bigatuma amakuru yoherezwa mu buryo bwihuse kuri platforms z'ibicu cyangwa sisitemu za SCADA kugira ngo zigenzurwe kandi zisesengurwe kure. Modele zigezweho zifite kandi imikorere yo kwisuzuma ishobora kumenya umwanda wa electrode, kwangirika k'umurongo, cyangwa kubangamira ibimenyetso, igatanga ubutumwa ku gihe kugira ngo igabanye igihe cyo kudakora kitateganijwe. Ibikoresho bimwe na bimwe byo mu rwego rwo hejuru binahuza ubushobozi bwo gukoresha mudasobwa, bigatuma amakuru yo mu gace aherereyemo atunganywa kandi agakorwa mbere y'igihe, ibyo bikaba byongera imikorere myiza kandi bikagabanya ikiguzi cyo kuyasana.
Mu gusoza, ibipimo by'amashanyarazi byabaye inkingi ikomeye mu gupima amazi y'inganda, bitanga ubushobozi bwo guhuza ibintu, gukora neza no kwizerwa mu nzego zitandukanye. Ubushobozi bwabyo bwo gufata amazi y'inganda akomeye, kugabanya igihombo cy'ingufu, no guhuza na sisitemu z'ubwenge bituma biba ingenzi mu bikorwa bya none by'inganda byibanda ku gukora neza, kuramba, no kubahiriza amategeko. Uko iterambere ry'ikoranabuhanga mu nganda rikomeza gutera imbere, ibipimo by'amashanyarazi bizatera imbere nta gushidikanya, bishyiremo ikoranabuhanga rigezweho kugira ngo bihuze n'ibikenewe mu nganda zikomeye kandi bigire uruhare mu mpinduka zikomeje mu nganda n'imicungire y'umutungo ku isi.
