Kuyerekeza Pakati pa Ma Electromagnetic Flow Meters ndi Ma Ultrasonic Flow Meters

2.Mitundu ya Madzi Oyezedwa

• EMF:
  Ma electromagnetic flow meter ndi oyenera kuyeza madzi oyendetsera mpweya, monga madzi, zimbudzi, mankhwala, ndi matope. Sangathe kuyeza madzi osayendetsa mpweya monga mafuta ndi mpweya.

• USM:
  Ma ultrasound flow meters amatha kuyeza madzi oyendetsera mpweya komanso osayendetsa mpweya. Ndi osinthasintha ndipo amatha kugwira madzi okhala ndi tinthu tomwe timapachikidwa, thovu, kapena mpweya m'njira zina.

3.Kulondola

• EMF:
  Ma electromagnetic flow meter ndi olondola kwambiri, ndipo nthawi zambiri amawerengera pakati pa ± 0.5% mpaka ± 1% ya kuwerenga. Amapereka miyeso yopitilira komanso yeniyeni, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe deta yolondola ya flow ikufunika.

• USM:
  Kulondola kwa zoyezera kuyenda kwa ma ultrasound kumatha kusiyana kutengera mtundu ndi momwe zimagwiritsidwira ntchito. Pamadzi oyera, kulondola nthawi zambiri kumakhala pakati pa ±1% ndi ±2%, koma pamadzi okhala ndi zinthu zolimba kapena thovu la mpweya, kulondola kumatha kuchepa. Ma Doppler ultrasonic mita, makamaka, amatha kukhala ndi kulondola kochepa chifukwa cha kusokonezeka kwa chizindikiro kuchokera ku tinthu tating'onoting'ono kapena thovu.

4.Kukhazikitsa ndi Kusamalira

• EMF:
  Ma electromagnetic flow meter nthawi zambiri amafunikira gawo lolunjika la chitoliro kuti ayese molondola, zomwe zingachepetse kusinthasintha kwa kuyika. Komabe, akangoyikidwa, sasamalidwa bwino chifukwa alibe zida zosuntha. Mavuto ofala kwambiri pakukonza ndi kuwonongeka kwa ma electrode kapena kuipitsidwa ndi zinthu zina, monga slurry.

• USM:
  Ma ultrasound flow mita amatha kuyikidwa kunja kwa chitoliro, zomwe zimapangitsa kuti zikhale zosavuta kuzipeza. Izi ndizothandiza kwambiri pamapaipi omwe ndi ovuta kuwapeza. Kukhazikitsa kwake ndikosavuta, koma kungafunike kuyesedwa nthawi zonse kuti kukhale kolondola. Ma ultrasound mita alibenso magawo osuntha, zomwe zimachepetsa kufunikira kokonza thupi. Komabe, amatha kukhudzidwa ndi kusintha kwa kutentha kwa madzi kapena kapangidwe kake.

5.Mtengo

• EMF:
  Ma electromagnetic flow meter nthawi zambiri amakhala okwera mtengo kuposa ma ultrasound flow meter, makamaka poyesa kulondola kwambiri kapena kugwiritsa ntchito mwapadera. Mtengo wake umasiyana malinga ndi zinthu monga kukula kwa chitoliro ndi zinthu.

• USM:
  Ma flow meter a ultrasound nthawi zambiri amakhala otsika mtengo kuposa ma electromagnetic meter, makamaka pankhani ya ma clamp-on models. Amapereka njira yotsika mtengo kwambiri yoyezera zinthu zosavulaza kapena kuyang'anira kayendedwe ka madzi kwakanthawi.

6.Mbiri Yoyenda ndi Kukula kwa Chitoliro

• EMF:
  Ma electromagnetic flow meter sakhudzidwa ndi kusintha kwa flow profile, bola ngati madziwo ali ndi mphamvu yoyendetsa magetsi. Komabe, amafunika payipi ya mainchesi enaake kuti igwire bwino ntchito. Chitoliro chaching'ono kwambiri kapena chachikulu kwambiri chingayambitse zolakwika.

• USM:
  Ma flow meters a ultrasound ndi ozindikira bwino momwe flow specific imayendera, ndipo kulondola kwake kungakhudzidwe ndi flow yosasunthika kapena yosasinthasintha. flow conditioner, monga kugwiritsa ntchito flow straighteners, nthawi zambiri amafunika kuti zitsimikizire kuti ma flow lighteners ndi olondola. Amapezeka m'makulidwe osiyanasiyana ndipo amatha kusinthasintha malinga ndi momwe amaikidwira.

7.Mapulogalamu

• EMF:
  Yabwino kwambiri pakugwiritsa ntchito madzi ambiri otulutsa mpweya monga kuyeretsa madzi otayidwa, kukonza mankhwala, njira zogawa madzi, ndi kuyeza matope.

• USM:
  Yoyenera kugwiritsa ntchito madzi oyendetsera mpweya komanso osayendetsa mpweya, kuphatikizapo mafuta, gasi, madzi, ndi mankhwala. Ndi othandiza kwambiri m'mafakitale komwe kumafunika kuyeza kosawononga mpweya, monga machitidwe a HVAC, mapaipi a gasi achilengedwe, ndi mayendedwe a mafuta.

8.Ubwino ndi Kuipa

• Ubwino wa EMF:

  • Kulondola kwambiri kwa madzi oyendetsera mpweya.
  • Palibe zida zosunthika, kukonza kochepa.
  • Yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

• Zoyipa za EMF:

  • Zochepa pa madzi oyendetsera mpweya.
  • Kukhazikitsa kumafuna gawo lolunjika la chitoliro.
  • Mtengo wokwera poyerekeza ndi ma ultrasound mita.

• Ubwino wa USM:

  • Sizowononga, zomwe zimapangitsa kuti kukhazikitsa kukhale kosavuta.
  • Yoyenera madzi oyendetsera mpweya komanso osayendetsa mpweya.
  • Kukhazikitsa kosinthasintha, kuphatikizapo mitundu yolumikizira.

• Zoyipa za USM:

  • Kulondola kungakhudzidwe ndi zinthu zamadzimadzi, monga kugwedezeka kapena kukhalapo kwa zinthu zolimba.
  • Mitengo yokwera yoyika pa mitundu ina (monga, ma ultrasound meters oyendera nthawi yoyendera).
  • Imafunika kuyesedwa nthawi ndi nthawi, makamaka pa ntchito zovuta.

Mapeto

Ma electromagnetic flow meter onse ndi ma ultrasonic flow meter onse ali ndi ubwino wawo wapadera, ndipo kusankha pakati pa awiriwa kumadalira zofunikira za ntchitoyo. EMF ndi yabwino kwambiri poyeza molondola madzi oyendetsera magetsi, makamaka m'mafakitale monga kuchiza madzi ndi mankhwala. Mosiyana ndi zimenezi, ma ultrasound meter amapereka njira zosiyanasiyana, makamaka m'magwiritsidwe ntchito osalowerera muyeso wa madzi, ndipo amatha kuthana ndi mitundu yosiyanasiyana ya madzi, kuphatikizapo oyendetsera magetsi ndi osayendetsa magetsi.

Kwa mafakitale omwe amafunikira kulondola kwambiri poyesa zakumwa zoyendetsa magetsi komanso komwe mtengo wake uli woyenera, ma electromagnetic flow mita ndi chisankho chabwino. Kuti mupeze mayankho osavulaza komanso osinthasintha pamitundu yosiyanasiyana yamadzimadzi ndi kukula kwake, ma ultrasound flow mita amapereka njira ina yabwino kwambiri. Kumvetsetsa mawonekedwe amadzimadzi ndi malo ogwirira ntchito ndikofunikira kwambiri posankha ukadaulo woyenera wa flow mita.
