E ʻimi ana kēia alakaʻi i nā ʻike koʻikoʻi e pili ana i nā mea kani kahe, e kōkua ana iā ʻoe e hoʻokele i nā koho me ka hilinaʻi. Inā he ʻenekinia ʻoe e hoʻopololei ana i kahi paipu a i ʻole ka manakia e hoʻolilo kālā no ka hoʻonui ʻana, e luʻu kākou i nā mea pono o nā ʻano mika kahe, ko lākou ikaika, a me nā ʻōlelo aʻoaʻo kūpono no ke koho ʻana.

Ka Hoʻomaopopo ʻana i nā Meter Flow: No ke aha lākou i mea nui ai i ka ʻenehana ʻenehana

Kaheukuishe ʻāpana pōhaku kihi i ka hana ʻenehana, e hoʻomalu ana i nā mea āpau mai nā hopena kemika a hiki i ka hāʻawi ʻana i ka ikehu. I ka makahiki 1970, ua paʻa ka ʻenehana kaomi ʻokoʻa i 80% o ka mākeke, akā ua hoʻokomo ka mea hou i nā koho ʻoi aku ka naʻauao a me ka maʻalahi. I kēia lā,ke koho ʻana i kahi kahemikakomonā mea kaulike e like me ke ʻano wai, nā kūlana hana, nā pono kūpono, a me ka waihona kālā. Mai nā ʻōnaehana kōmike ma nā wahi paʻakikī, e like me nā rigs aila o waho a i ʻole nā ​​lumi hoʻomaʻemaʻe lāʻau lapaʻau, ke hoʻohālikelike nei ke kī i nā hiʻohiʻona o ka mika i kāu noi kikoʻī e pale aku ai i ka downtime a me ka heluhelu pololei ʻole.

E ʻimi kēia pou i ʻehiku mau ʻāpana nui o nā mika kahe i hoʻohana mau ʻia i ka ʻoihana, e hōʻike ana i kā lākou mau hiʻohiʻona, nā mea maikaʻi, nā pōʻino, a me nā noi ma nā ʻano ʻano. E hahai wale i ka haku i nā ʻenehana i wehewehe ʻia no ke koho ʻana i kahi mika kahe!

1. ʻOkoʻa Pressure Flow Meter: Ka Mea Hana Pono

Pumi like ʻoleana anakoeʻo ka ʻenehana kahe i hoʻohana nui ʻia, hiki ke hoʻohana i ka wai hoʻokahi-phase ma lalo o nā kūlana like ʻole, me nā wela kiʻekiʻe a me nā kaomi. I kona wā kiʻekiʻe i ka makahiki 1970, ua hopu ʻo ia i 80% o ka mākeke no ke kumu maikaʻi. Loaʻa kēia mau mika i kahi mea throttling (e like me ka orifice plate, nozzle, Pitot tube, a i ʻole averaging Pitot tube) i hui pū ʻia me kahi transmitter.

Hoʻopaʻa ka mea throttling i ke kahe ʻana o ka wai, e hana ana i kahi ʻokoʻa puʻe i luna a i lalo e like me ke kahe kahe. ʻO nā papa orifice ke koho ma muli o ko lākou maʻalahi a me ka maʻalahi o ka hoʻokomo. I ka wā i hana ʻia a hoʻokomo ʻia i kēlā me kēia maʻamau (e noʻonoʻo i ka ISO 5167), hāʻawi lākou i nā ana hilinaʻi me ka ʻole pono o ka calibration kahe maoli akā he nānā wikiwiki wale nō.

ʻO kēlā ʻōlelo, ʻo nā mea throttling a pau e hoʻokomo i ka nalo paʻa mau. Hiki i kahi pā puka puka ʻoi aku ke lilo i 25-40% o ke kaomi ʻokoʻa kiʻekiʻe, e hoʻohui i nā kumukūʻai ikehu no nā hana nui. ʻO nā pait pait, ma kekahi ʻaoʻao, ʻaʻohe nalo akā ua maʻalahi i ka hoʻololi ʻana i ka ʻaoʻao kahe, ʻoiai hiki i ka haunaele ke hoʻopau i kā lākou heluhelu.

I loko o kahi mea kanu petrochemical, ua hoʻololi nā mea hoʻohana i nā pā orifice kahiko no nā paipu Venturi e hōʻemi i ka hāʻule ʻana o ke kaomi, e hoʻemi ana i ka hoʻohana ʻana i ka ikehu pauma he 15%. No laila, i ka wā e pili ana i nā wai ʻeleʻele a i ʻole nā ​​slurries, pono e noʻonoʻo i ka awelika o nā paipu Pitot no ka pololei ʻoi aku ka maikaʻi o nā kahe like ʻole. ʻO ka mea kūpono e haʻi ʻia ʻo ia e hōʻoia mau ma ka liʻiliʻi he 10-20 mau anawaena paipu o ka holo pololei i uka e hoʻopaʻa i ka profile kahe, a i ʻole e paʻa nā mea hoʻohana i nā poʻo calibration.

2. Nā Meter Flow Area Variable: ʻO ka maʻalahi e hui me ka versatility

ʻO kahōʻailona rotameter hōʻailonanā mika kahe ʻāpana ʻokoʻa, kahi e piʻi ai kahi lana i loko o kahi paipu liʻiliʻi e like me ka nui o ke kahe. ʻO kā lākou kūlana kūʻokoʻa? Heluhelu pololei, ma ka pūnaewele me ka mana o waho, kahi kūpono no ka nānā wikiwiki ʻana i ke kula.

Hele mai kēia i ʻelua mau ʻono nui: ʻo nā rotameters paipu aniani no nā mea hoʻolaha ambient, non-corrosive e like me ka ea, nā kinoea, a i ʻole argon, e hāʻawi ana i ka ʻike maopopo a me ka maʻalahi o ka heluhelu;ametalapaipumīkini hoʻololinā manaʻome nā hōʻailona magnetic no nā hiʻohiʻona kiʻekiʻe a i ʻole ke kaomi kiʻekiʻe. Hiki i ka mea hope ke hoʻopuka i nā hōʻailona maʻamau no ka hoʻohuimenā mea kākau moʻoleloorhuinahalike.

Loaʻa nā ʻano ʻokoʻa hou i nā hoʻolālā conical i hoʻopiha ʻia i ka puna me nā keʻena condensate ʻole, e kaena ana i ka ratio turndown 100:1 a me ka puka laina, kūpono no ke ana mahu.

Ke kamaʻilio nei e pili ana i nā noi ākea, koho ʻia nā rotameters he nui e kau ʻia i loko o nā hoʻonohonoho lab no ka hui ʻana o ke kinoea, e mālama ai i nā kumukūʻai uwea no ka pono ʻole o ka mana. Akā ke nānā nei i nā haʻalulu, hiki i nā rotameters ke hoʻoulu i ka jitter a me nā heluhelu wahaheʻe. I ka hoʻomaikaʻi ʻana i ka brewery, no ka laʻana, ʻo nā kumu hoʻohālikelike metala e mālama i nā kahe wort wela, e hoʻolōʻihi i ke ola o ka lawelawe ʻana i ʻekolu manawa, ʻoiai nā ʻano aniani i hoʻopaʻa ʻia me nā linings PTFE he koho pili kālā, akā pono nā mea hana e calibrate iā lākou i kēlā me kēia makahiki e mālama i ka 1-2% pololei.

3. Vortex Flow Meters: Oscillation no ka pololei

Nā mika vortex, he laʻana nui o nā ʻano oscillatory, e kau i kahi kino bluff ma ke ala kahe, e hana ana i nā vortices ʻokoʻa e pili ana ka alapine i ka wikiwiki. ʻAʻohe ʻāpana hoʻoneʻe ʻo ia ka mea hiki ke hana hou, lōʻihi, a me ka mālama liʻiliʻi.

ʻO ka paʻa ʻana i nā pono e like me ka laulā laina ākea, ka pale ʻana i ka mahana, ke kaomi, ka nui, a i ʻole ka hoʻololi ʻana o ka viscosity, haʻahaʻa haʻahaʻa haʻahaʻa, a me ke kiʻekiʻe kiʻekiʻe (0.5-1%), ʻo nā mika kahe vortex a hiki i 300 ° C a me 30 MPa, e hoʻolilo iā lākou i mea maʻalahi no nā kinoea, wai, a me ka mahu.

ʻOkoʻa ke ʻano o ka ʻike ʻana i nā mika kahe vortex ma ka waena: kūpono nā mea ʻike piezoelectric no ka mahu, ka wela a i ʻole nā ​​mea kani kani kani e kūpono i ka ea, a kokoke i nā koho ʻike āpau e hana no ka wai. E like me nā papa orifice, hoʻoholo ʻia ka coefficient kahe e nā ana o ka mika.

I ka papahana pipeline kinoea maoli, ʻoi aku ka maikaʻi o nā vortex mika i nā turbines i nā kahe ʻana, e hōʻemi ana i nā hewa mai 5% a i lalo o 1%. Hoʻopili lākou i ka hoʻokomo ʻana, e hōʻoiaʻiʻo ana i ka holo pololei a pale aku i kahi kokoke i nā valve. I ka hiki ʻana mai i nā ʻano e puka mai nei, nā mika vortex uila me ke ola pākaukau a hiki i 10 mau makahiki no nā wahi mamao.

4. Electromagnetic Flow Meter: Conductive Fluids 'Oi Loa

Nā mika electromagnetic, a i ʻole nā ​​mika, e hoʻohana i ke kānāwai o Faraday, e like me kēia: ʻo nā wai conductive e ʻoki ana i loko o ke kahua magnetic e hoʻoulu i ka volta e like me ke kahe. Hoʻopaʻa ʻia i ka media conductive, ʻaʻole pili kēia mau mika i ka wela, ke kaomi, ka nui, a i ʻole ka viscosity—ma ka manaʻo, ma ka liʻiliʻi loa—me ka huli ʻana o 100:1 a me 0.5% pololei. ʻO ka nui o ka paipu mai 2mm a 3m, kūpono i ka wai, slurries, pulps, a i ʻole corrosive.

Hoʻopuka nā mika kahe electromagnetic i nā hōʻailona nāwaliwali (2.5-8 mV ma ka laulā piha), no laila pono ka hana ʻana i ka pale a me ka hoʻopaʻa ʻana kūpono i mea e pale ai i ka hoʻopilikia ʻana i nā kaʻa.

ʻOi aku ka maikaʻi o nā mika kahe electromagnetic i nā mea kanu hoʻomaʻemaʻe wai, me ka hilinaʻi e ana i nā wai lepo e like me nā slurries me ka ʻole o ka pani ʻana. ʻAʻole like me nā mīkini mīkini, ʻaʻohe wahi neʻe nā mika mag. No nā wai ʻino, e like me ka wai ʻawaʻawa, hiki i ka hoʻomaikaʻi ʻana i nā mika mag me PFA-lined hiki ke hōʻemi i ka pono o ka mālama ʻana a hiki i 50% e like me ka mea i ʻike ʻia ma kahi mea kanu hou. Hoʻohui hou, loaʻa ka mana o nā mika i hoʻohana ʻia i ka pākaukau no ka ana wai mamao, e hāʻawi ana i ka maʻalahi ma nā wahi waho-grid me ka mālama ʻana i ka hilinaʻi like ʻole clog-free.

5. Ultrasonic Flow Meters: Non-Intrusive Innovation

Kahe kani kanimikahele maima nā ʻano kumu ʻelua: Doppler a me ka manawa-o-lele (TOF).DopplermikaanaKahe ʻana ma ka ʻike ʻana i nā hoʻololi alapine mai nā ʻāpana i hoʻokuʻu ʻia, e hoʻolilo iā lākou i mea kūpono no ka wikiwiki kiʻekiʻe, nā wai lepo e like me nā slurries, akā ʻoi aku ka maikaʻi no nā māmā haʻahaʻa a i ʻole nā ​​ili paipu ʻino.

ʻO nā mika TOF, e helu ana i ke kahe ma muli o ka ʻokoʻa manawa o nā hawewe kani ultrasonic e hele pū ana me ke kahe, ʻoi aku ka maikaʻi i nā wai maʻemaʻe like ʻole e like me ka wai, e koi ana i ka uila pololei no ka pololei. Hoʻonui ka hoʻolālā TOF multi-beam i ka hana i nā kahe kūpikipiki, hāʻawi i ka hilinaʻi nui aʻe i nā ʻōnaehana paʻakikī.

I loko o kahi ʻōnaehana wai anuanu, hoʻopaʻa ʻia nā mika kani ultrasonic TOF i hoʻopakele i nā tausani ma ka hoʻopau ʻana i ka pono no ka ʻoki ʻana a i ʻole ka pani ʻana i ka paipu, loaʻa ka 1% pololei me ka calibration kūpono. Eia nō naʻe, hiki i nā ʻōhū ea a i ʻole nā ​​uhi paipu ke hoʻopau i ka heluhelu ʻana, no laila he mea koʻikoʻi ka loiloi o ka pae. No ka loiloi kahua, waiwai nui nā ʻāpana ultrasonic portable, e hāʻawi ana i nā diagnostics wikiwiki me ka ʻole o ka downtime ʻōnaehana.

6. ʻO nā Meter Flow Turbine: ka wikiwiki a me ka pololei i ka neʻe ʻana

Ke kahe ʻana o ka turbinemika hanama ke kumu o ka mālama ʻana i ka manawa, kahi e holo ai ka wai i kahi rotor, a pili pono ka wikiwiki o ka rotor i ka holo kahe. ʻO kēia mau mika ka mana ma nā noi e koi ana i ka pololei kiʻekiʻe, me nā hoʻolālā kikoʻī kinoea e hōʻike ana i nā kihi ʻili liʻiliʻi a me nā lau ʻoi aku ka maikaʻi o ka hana ma nā wai haʻahaʻa haʻahaʻa. Hāʻawi lākou i ka pololei ʻokoʻa (0.2-0.5%, a i ʻole 0.1% i nā hihia kūikawā), kahi 10: 1 turndown ratio, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka hana ikaika ma lalo o nā puʻe kiʻekiʻe, akā makemake i nā wai maʻemaʻe a me ka holo pololei ʻana o ka paipu pololei e pale i nā hewa i hoʻoulu ʻia.

I loko o kahi ʻōnaehana wahie lele,kahe ʻana o ka turbinemikahōʻoiaʻiʻokiko pololei no ka hoʻoili mālama, koʻikoʻi no ka pololei pili. ʻO ka nui o ka lua liʻiliʻi e hoʻonui i ka naʻau i ka nui o ka wai a me ka viscosity, no laila pono ka hoʻomaʻemaʻe mua ʻana e pale i nā hewa pili i ka ʻōpala. Ua hoʻomaikaʻi ka hilinaʻi ʻana o nā hoʻolālā hybrid me nā pickup magnetic ma o ka hōʻemi ʻana i ka lole mīkini.

7. Nā Meter Kahe Hoʻoneʻe maikaʻi: Volumetric Precision

ʻO nā mika kahe o ka hoʻoneʻe maikaʻi ʻana e ana i ka kahe ma ka hoʻopaʻa ʻana a me ka hoʻoneʻe ʻana i ka nui o ka wai paʻa me kēlā me kēia hoʻololi ʻana, me ka hoʻohana ʻana i nā hoʻolālā e like me ka oval gear, rotary piston, a i ʻole nā ​​ʻano scraper. Hāʻawi nā mika oval gear i ka ratio turndown 20:1 a me ka pololei kiʻekiʻe (maʻamau 0.5% a ʻoi aku paha) akā hiki ke hoʻopaʻa ʻia mai nā ʻōpala i loko o ka wai. ʻOi aku ka maikaʻi o nā mika piston Rotary i ka lawelawe ʻana i nā puke nui, ʻoiai ʻo kā lākou hoʻolālā e ʻae i ka leaka liʻiliʻi, e hoʻopilikia i ka pololei i nā hiʻohiʻona haʻahaʻa.

ʻAʻole i hoʻopilikia ʻia e ka viscosity wai, kūpono nā mika PD no nā wai e like me ka aila a me ka wai, akā ʻaʻole kūpono i nā kinoea a i ʻole ka mahu ma muli o kā lākou mīkini volumetric.

I loko o kahi mea kanu meaʻai, ʻo nā mika PD, ʻoi aku ka nui o nā ʻano oval gear, he mea koʻikoʻi no ka hoʻopaʻa ʻana i ka ʻāpana o nā syrups viscous, e hōʻoia ana i ka maikaʻi o ka huahana. Eia nō naʻe, ʻo nā ʻōpala i loko o nā syrup i kānana ʻole i hoʻokumu i nā pahu i kekahi manawa, e hōʻike ana i ka pono o nā ʻōnaehana kānana ikaika. ʻO nā hoʻolālā Clean-in-place (CIP) i hōʻemi nui ʻia i ka manawa hoʻomaha ma o ka hoʻomaʻamaʻa ʻana i ka mālama ʻana, kahi mea hoʻololi pāʻani no nā laina kiʻekiʻe.

Ke koho ʻana i ka Meter Flow kūpono: Nā ʻōlelo aʻoaʻo no ka holomua

He mea koʻikoʻi ke koho ʻana i ka mika kahe kūpono no ka hoʻomaikaʻi ʻana i nā kaʻina hana ʻoihana, no ka mea, ʻaʻohe mika hoʻokahi i kūpono i kēlā me kēia noi. No ka hana ʻana i kahi koho ʻike, e loiloi i nā mea nui: nā waiwai wai (e laʻa, ka viscosity, corrosiveness, a i ʻole ka ʻāpana ʻāpana), ka pae kahe (ka palena liʻiliʻi a me ka nui), pono pono (mai ka 0.1% no ka hoʻololi ʻana i ka mālama a hiki i ka 2% no ka nānā maʻamau), nā palena hoʻonohonoho (e like me ka nui o ka paipu, nā koi holo pololei, a i ʻole nā ​​palena o ka lumi), a me nā kumu kūʻai o ka mālama ʻana, ke kūʻai ʻana.

Ma ke kaupaona ʻana i kēia mau mea e pili ana i kāu pono kaʻina hana, kūpono me ka hoʻāʻo hoʻokele a i ʻole ke kūkākūkā mea kūʻai aku, hiki iā ʻoe ke koho i kahi mika e kaulike ana i ka hana a me ke kālā.
