Mu kukonza mankhwala, kuteteza chilengedwekuchiza madzi otayira, kupanga mankhwala, ndi mafakitale opanga mapepala, kuyeza molondola kayendedwe ka asidi wamphamvu ndi zakumwa zowononga za alkali kwakhala vuto lalikulu kwa nthawi yayitali. Zipangizo zoyezera kayendedwe ka madzi wamba, monga ma turbine ndi ma vortex flowmeters, zimakhala ndi dzimbiri, kutsekeka, komanso kusokonekera kwa deta zikagwiritsidwa ntchito pazinthu zowononga kwambiri, zomwe zimapangitsa kuti ntchito yokonza nthawi zambiri, ndalama zambiri zosinthira, komanso ntchito zosakhazikika zamafakitale. Monga chida choyezera cholondola kwambiri komanso chodalirika, electromagnetic flowmeter yakhala njira yabwino kwambiri yodziwira kayendedwe ka madzi amphamvu ndi zakumwa za alkali, kudalira mfundo yake yapadera yogwirira ntchito komanso kapangidwe kake koletsa dzimbiri.
Magetsi amagetsi zoyezera kuyendaamagwira ntchito motsatira lamulo la Faraday la kulowetsa mphamvu zamagetsi. Madzi oyendetsera magetsi akamayenda kudzera mu mphamvu ya maginito yofanana mkati mwa chubu choyezera, madziwo amadula mizere ya kulowetsa mphamvu zamagetsi ndikupanga chizindikiro cha magetsi choyambitsa. Kutalika kwa magetsi amenewa kumagwirizana mwachindunji ndi liwiro lapakati la madziwo. Pambuyo posonkhanitsidwa ndi kukonzedwa ndi electrode yolondola kwambiri ndi makina otumizira, kuyenda kwa madzi nthawi yeniyeni kumawerengedwa molondola. Ubwino waukulu wa mfundo yogwirira ntchito iyi ndikuti palibe magawo osuntha kapena zigawo zozungulira mkati mwa chubu choyezera, zomwe zimapangitsa kuti pasakhale kutayika kwa mphamvu komanso palibe cholepheretsa kuyenda kwa madzi. Kapangidwe kameneka kamapewa kuwonongeka kwa makina ndi kutsekeka kwa tinthu, komwe kumagwirizana bwino ndi kufunika koyezera kosalekeza kwa mankhwala owononga.
Kusinthasintha kwabwino kwambiri ku asidi wamphamvu ndi zakumwa za alkali kumachokera ku kufananiza kwa akatswiri oletsa dzimbiri, komwe ndi mpikisano waukulu wa ma electromagnetic flowmeters apamwamba kwambiri. Pazinthu zokhala ndi asidi wambiri monga hydrochloric acid, sulfuric acid, ndi nitric acid, ma electrode a tantalum ndi PTFE (polytetrafluoroethylene) zikugwiritsidwa ntchito. Chitsulo cha Tantalum chimalimbana ndi dzimbiri kwambiri ndi ma acid amphamvu ambiri ndi ma oxidizing media, pomwe PTFE imalimbana ndi dzimbiri komanso mankhwala popanda kuchitapo kanthu ndi zakumwa za acidic. Pazinthu zokhala ndi alkali zolimba kuphatikiza sodium hydroxide ndi potassium hydroxide solutions, ma electrode a Hastelloy C alloy ndi rabara kapena PFA lining zimakonzedwa. Kuphatikiza kwazinthu izi kumatha kukana kuwonongeka kwa mankhwala kwa nthawi yayitali, kupewa kukalamba kwa ma electrode ndi lining, ndikuwonetsetsa kuti magwiridwe antchito okhazikika m'malo ovuta owononga.
Poyerekeza ndi zida zina zoyezera kayendedwe ka madzi,zoyezera kuyenda kwa magetsiZimasonyeza ubwino wosasinthika pakuyeza kwapakati kowononga. Choyamba, sizikhudzidwa ndi kukhuthala kwa madzi, kutentha, kuchulukana, ndi tinthu tolimba, zomwe zimathandiza kuyeza bwino madzi owononga okhala ndi kuchuluka kosiyanasiyana komanso madzi osakanikirana amadzimadzi olimba a magawo awiri. Kachiwiri, kulondola koyezera kumatha kufika ±0.5% kapena ±0.2%, kukwaniritsa miyezo yokhwima yoyezera ya mankhwala, kuyang'anira kutulutsa madzi otayira m'mafakitale, ndi kuyeza mayendedwe a mapaipi. Kuphatikiza apo, kapangidwe kotsekedwa kophatikizidwa ndi IP68 yoteteza kwambiri kumalola chidacho kuti chizolowere malo ogwirira ntchito okhala ndi chinyezi komanso owononga, okhala ndi moyo wopitilira zaka 10 komanso ndalama zochepa kwambiri zokonzera pambuyo pake.
Pakadali pano, anti-corrosionzoyezera kuyenda kwa magetsiAgwiritsidwa ntchito kwambiri m'mafakitale apadziko lonse lapansi. M'mafakitale opanga mankhwala abwino, amayesa molondola mayendedwe ndi kusonkhanitsa kwa zinthu zopangira asidi ndi alkali kuti atsimikizire kuti njira yopangira ndi yolondola. M'mafakitale oteteza chilengedwe, amawunika momwe madzi otayira ochokera ku asidi amayendera m'njira zotsukira zinyalala kuti athandize mabizinesi kukwaniritsa miyezo yotulutsa madzi. M'mafakitale opanga mapepala ndi nsalu, amathandizira kuzindikira kuyenda kwa madzi oyeretsera ndi madzi otsukira a alkaline. Kuphatikiza apo, chotumizira chanzeru chimatha kutulutsa zizindikiro za analog za 4-20mA ndi zizindikiro zolumikizirana pa digito, ndikuzindikira kulumikizana kosasunthika ndi makina a mafakitale a PLC ndi DCS kuti athandizire kupanga zokha komanso kuyang'anira deta yakutali.
Pomaliza, ndi mfundo yake yasayansi yoyambitsa, kapangidwe kaukadaulo kotsutsana ndi dzimbiri, kulondola kwambiri pakuyeza komanso magwiridwe antchito okhazikika,choyezera kuyenda kwa magetsiyathetsa kwathunthu ululu wa asidi wamphamvu ndi zakumwa zowononga za alkali. Sikuti zimangowonjezera kulondola ndi kukhazikika kwa kuyeza madzi a mafakitale komanso zimachepetsa ndalama zogwirira ntchito ndi kukonza zida, kukhala chida chofunikira kwambiri choyezera m'mafakitale amakono a mankhwala ndi kuteteza chilengedwe.
