ʻO nā slurries, ma ke ʻano he mau hui paʻakikī o nā wai a me nā ʻāpana paʻa, he mea nui ia i nā ʻoihana e like me ke kālai ʻana, ka hana kemika, ka mālama ʻana i ka wai ʻino, a me ke kūkulu ʻana. He mea nui ka ana pololei ʻana o ke kahe ʻana o nā slurries no ka hoʻomaikaʻi ʻana i nā kaʻina hana, ka kaohi ʻana i nā kumukūʻai, a me ka hōʻoia ʻana i ka palekana hana. Ma waena o nā ʻenehana ana kahe like ʻole, kū nā mika kahe electromagnetic (EMF) no ko lākou mau pono kūikawā i ka lawelawe ʻana i nā pilikia i kau ʻia e nā slurries abrasive, viscous, a me nā solids kiʻekiʻe.
Hoʻokumu ʻia ke kumumanaʻo hana o nā EMF ma ke kānāwai o Faraday no ka hoʻokomo electromagnetic. Ke kahe ka slurry conductive ma o kahi kahua magnetic i hana ʻia e nā coils o ka mika, hoʻoulu ia i kahi ikaika electromotive (EMF) e like me ka wikiwiki o ke kahe ʻana, ka ikaika o ke kahua magnetic, a me ka mamao ma waena o nā electrodes. ʻIke ʻia kēia voltage i hoʻokomo ʻia e nā electrodes i kau ʻia ma ka paia pipeline, a hoʻololi ka flowmeter iā ia i kahi heluhelu kikoʻī o ka nui o ke kahe. ʻIke ʻia, ana pololei nā EMF i ka nui o ke kahe ʻana o ka leo, me ka hoʻopilikia ʻole ʻia e ka viscosity slurry, ka density, a i ʻole nā loli o ka mahana—nā kumu koʻikoʻi e hoʻopilikia i nā ʻano mika ʻē aʻe.
ʻO kahi pōmaikaʻi nui o nā EMF no nā noi slurry ʻo kā lākou hoʻolālā ʻaʻole komo a piha paha. Loaʻa i nā EMF piha kahi ʻano paipu pololei me ka ʻole o nā ʻāpana neʻe a i ʻole nā mea keakea, e hoʻopau ana i ka pilikia o ka clogging, wear, a i ʻole ka pohō kaomi i hoʻokumu ʻia e nā ʻāpana slurry. Hōʻoia kēia hoʻolālā i ke kahe slurry i keakea ʻole ʻia a hoʻemi i nā pono mālama, kahi pōmaikaʻi koʻikoʻi no nā slurries abrasive e like me nā tailings mining a i ʻole nā hui sima e hōʻino maʻalahi i nā mika kahe mechanical.
Hōʻike pū nā EMF i ka hiki ke hoʻololi maikaʻi loa i nā waiwai slurry like ʻole. Hana pono lākou me nā slurries e loaʻa ana nā wai conductive (e laʻa, nā slurries wai) a me nā ʻāpana paʻa o nā nui like ʻole, mai nā sediments maikaʻi a hiki i nā aggregates coarse. Hoʻolako ʻia nā hiʻohiʻona EMF holomua me nā electrodes corrosion-resistant (i hana ʻia me nā mea e like me Hastelloy, titanium, a i ʻole tantalum) a me nā liners (rubber, PTFE, a i ʻole polyurethane), e hiki ai iā lākou ke kū i nā kūlana slurry koʻikoʻi, me nā mahana kiʻekiʻe a me ka corrosion kemika.
I ka hana ʻoihana, hoʻohana nui ʻia nā EMF ma nā ʻāpana lawelawe slurry. I ka hana mining, nānā lākou i ke kahe o nā slurries mineral (e laʻa, keleawe, slurries hao) i ka wā o ka unuhi ʻana a me ka hana ʻana, e hōʻoiaʻiʻo ana i ka lawe ʻana o ka ore kūpono a me ka kaohi ʻana i ke kaʻina hana. Hoʻohana nā hale hana mālama wai ʻino i nā EMF e ana i ke kahe slurry slurry, e kākoʻo ana i nā kaʻina hana hoʻohemo wai a me ka hoʻolei ʻana i ka sludge me ka mālama ʻana i nā lula kaiapuni. I ka ʻoihana kūkulu hale, ana pololei lākou i ke kahe slurry sima e mālama i nā lakio hui a hōʻoia i ka maikaʻi o ke kūkulu ʻana.
I mea e hoʻonui ai i ka pololei o ke ana ʻana, he mea nui kekahi mau noʻonoʻo hana. Pono ka slurry i ka conductivity lawa; pono nā slurries non-conductive (e laʻa, nā hui ʻaila) i ka mālama mua ʻana a i ʻole nā mika ʻē aʻe. ʻO ke kau ʻana kūpono, me ka lōʻihi kūpono o nā paipu pololei ma luna/iho, e pale aku i nā haunaele kahe. ʻO ka mālama mau ʻana, e like me ka hoʻomaʻemaʻe ʻana i nā electrodes a me ka nānā ʻana i nā liners no ke komo ʻana, mālama i ka hilinaʻi o ke ana ʻana. Manaʻo ʻia hoʻi ka calibration e kūʻē i nā ʻano maʻamau (e laʻa, nā pahu volumetric) no nā noi koʻikoʻi.
I ka ʻimi ʻana o nā ʻoihana i ka pono a me ka pololei kiʻekiʻe, ke hoʻomau nei nā EMF i ka ulu ʻana me nā ʻenehana akamai, e like me ka hana hōʻailona kikohoʻe a me ka hoʻoili ʻikepili uea ʻole, e hoʻomaikaʻi ana i ka nānā ʻana i ka manawa maoli a me nā mana kaohi mamao. ʻO ko lākou hiki ke lawelawe i nā kūlana slurry koʻikoʻi, i hui pū ʻia me ka pololei kiʻekiʻe a me ka mālama haʻahaʻa, e hoʻolilo i nā mika kahe electromagnetic i mea hana pono no ke ana ʻana o ke kahe slurry hou, e hoʻokele ana i ka maikaʻi o ka hana ma nā ʻāpana ʻoihana koʻikoʻi.
