Mita kwararar lantarki (Electromagnetic flowmeter) kayan aiki ne da ke amfani da ƙa'idar shigar da lantarki (electromagnetic induction) don auna kwararar ruwan da ke gudana bisa ga ƙarfin lantarki da aka haifar lokacin da ruwan da ke gudana ya ratsa ta filin maganadisu na waje.
To, ta yaya za a zaɓi kayan rufin ciki da na lantarki?

■ Neoprene (CR):
Polymer wanda aka samar ta hanyar polymerization na emulsion na monomer chloroprene. Wannan ƙwayar roba tana ɗauke da ƙwayoyin chlorine, don haka idan aka kwatanta da sauran robar da ake amfani da ita a gabaɗaya: Yana da kyakkyawan anti-oxidation, anti-ozone, ba mai ƙonewa ba, yana kashe kansa bayan wuta, juriyar mai, juriyar narkewa, juriyar acid da alkali, da juriyar tsufa da iskar gas. Kyakkyawan matsewa da sauran fa'idodi.
✔ Ya dace da auna kwararar ruwan famfo, ruwan masana'antu, ruwan teku da sauran hanyoyin sadarwa.
■ Robar Polyurethane (PU):
Ana yin polymer ɗinsa ta hanyar amfani da polyester (ko polyether) da kuma diisocyanamide lipid compound. Yana da fa'idodin tauri mai yawa, ƙarfi mai kyau, sassauci mai yawa, juriya mai yawa, juriya ga tsagewa, juriya ga tsufa, juriya ga ozone, juriya ga radiation da kuma kyakkyawan juriyar lantarki.
✔ Ya dace da auna kwararar ruwa kamar ɓangaren litattafan almara da ɓangaren litattafan ma'adinai.
■Polytetrafluoroethylene (P4-PTFE)
An shirya shi ta hanyar polymerization na tetrafluoroethylene a matsayin monomer. Farin kakin zuma, mai haske, juriya ga zafi, juriya ga sanyi, ana iya amfani da shi a cikin -180 ~ 260°C na dogon lokaci. Wannan kayan yana da halaye na juriya ga acid da alkali, juriya ga abubuwa daban-daban na halitta, juriya ga tafasa hydrochloric acid, sulfuric acid, aqua regia, da tsatsa mai ƙarfi na alkali.
✔ Ana iya amfani da shi don magance acid da gishirin alkali mai guba.
■Polyperfluoroethylene propylene (F46-FEP)
Yana da kyakkyawan kwanciyar hankali na sinadarai da kuma juriya ga radiation, haka kuma yana da kyawawan halaye na lantarki da na inji. Halayen sinadarai nasa sun yi daidai da polytetrafluoroethylene, tare da ƙarfin matsewa da ƙarfi, kuma ƙarfin tauri ya fi polytetrafluoroethylene kyau.
✔ Ana iya amfani da shi don magance acid da gishirin alkali mai guba.
■Copolymer na tetrafluoroethylene da perfluorocarbon ta hanyar vinyl ether (PFA)
Kayan rufin da aka yi amfani da shi don na'urar auna kwararar lantarki yana da halaye iri ɗaya na sinadarai kamar F46 kuma yana da ƙarfi mafi kyau fiye da F46.
✔Ana iya amfani da shi don magance acid da gishirin alkali mai guba.
