Uthelekiso Phakathi kweeMeter Flow zeElectromagnetic kunye neeMeter Flow zeUltrasonic

2.Iintlobo zoLwelo oluLinganisiweyo

• I-EMF:
  Iimitha zokuhamba kwe-electromagnetic zifanelekile ukulinganisa ulwelo oluqhuba umbane, olufana namanzi, indle, iikhemikhali kunye nodaka. Azinakulinganisa ulwelo olungahambisani nombane njengeoyile kunye neegesi.

• I-USM:
  Iimitha zokuhamba ze-ultrasonic zinokulinganisa zombini ulwelo oluqhubayo nolungaqhubiyo. Ziyakwazi ukusetyenziswa ngeendlela ezahlukeneyo kwaye zinokuphatha ulwelo oluneziqwenga ezixhonyiweyo, amaqamza, okanye neegesi kwezinye iinkqubo.

3.Ukuchaneka

• I-EMF:
  Iimitha zokuhamba kwe-electromagnetic zichaneke kakhulu, kwaye amanqanaba okuchaneka aqhelekileyo aphakathi kwe-±0.5% ukuya kwi-±1% yokufunda. Zibonelela ngemilinganiselo eqhubekayo, yexesha langempela, ezenza zifaneleke ukusetyenziswa apho kufuneka idatha echanekileyo yokuhamba.

• I-USM:
  Ukuchaneka kweemitha zokuhamba kwe-ultrasonic kunokwahluka ngokuxhomekeke kuhlobo kunye nokusetyenziswa. Kwiziselo ezicocekileyo, ukuchaneka kudla ngokuba phakathi kwe-±1% kunye ne-±2%, kodwa kwiziselo ezineziqina ezixhonyiweyo okanye amaqamza egesi, ukuchaneka kunokwehla. Iimitha ze-Doppler ultrasonic, ngakumbi, zinokuba nokuchaneka okuphantsi ngenxa yokuphazamiseka kwesignali evela kumaqhekeza okanye amaqamza.

4.Ukufakelwa kunye nokugcinwa

• I-EMF:
  Iimitha zokuhamba ze-electromagnetic zihlala zifuna icandelo lombhobho othe tye ukuze kulinganiswe ngokuchanekileyo, nto leyo enokunciphisa ukuguquguquka kokufakwa. Nangona kunjalo, xa sele zifakiwe, azilungiswa kakhulu kuba azinazo iindawo ezihambayo. Iingxaki eziqhelekileyo zokugcinwa ziquka ukuguguleka kwe-electrode okanye ukungcola kwezinye iinkqubo, ezifana ne-slurry.

• I-USM:
  Iimitha zokuhamba ze-ultrasonic zingafakelwa ngaphandle kumbhobho, nto leyo eyenza ukuba zibe lukhetho olungangenisi ntsholongwane. Oku kuluncedo kakhulu kwiipayipi ezinzima ukufikelela kuzo. Ukufakelwa kulula kakhulu, kodwa kunokufuna ukulinganiswa rhoqo ukuze kugcinwe ukuchaneka. Iimitha ze-ultrasonic azinazo iindawo ezihambayo, nto leyo enciphisa isidingo sokugcinwa ngokwasemzimbeni. Nangona kunjalo, zinokuchaphazeleka lutshintsho kubushushu bolwelo okanye ukwakheka kwazo.

5.Ixabiso

• I-EMF:
  Iimitha zokuhamba ze-electromagnetic zihlala zibiza kakhulu kuneemitha zokuhamba ze-ultrasonic, ingakumbi xa kulinganiswa ukuchaneka okuphezulu okanye usetyenziso olukhethekileyo. Ixabiso linokwahluka ngokuxhomekeke kwizinto ezifana nobukhulu bombhobho kunye nezinto ezisetyenziswayo.

• I-USM:
  Iimitha zokuhamba nge-ultrasonic zihlala zibiza kancinci kuneemitha ze-electromagnetic, ingakumbi kwimeko yeemodeli ze-clamp-on. Zibonelela ngesisombululo esingabizi kakhulu kwiimilinganiselo ezingangenisi okanye ukujonga ukuhamba kwexeshana.

6.Iprofayili Yokuhamba Kombhobho kunye nobungakanani bePipe

• I-EMF:
  Iimitha zokuhamba ze-electromagnetic azichaphazeleki kangako lutshintsho kwiprofayili yokuhamba kwamanzi, ukuba nje ulwelo luqhuba umbane. Nangona kunjalo, zifuna ububanzi bombhobho othile ukuze zisebenze kakuhle. Umbhobho omncinci kakhulu okanye omkhulu kakhulu unokukhokelela ekungachanekini.

• I-USM:
  Iimitha zokuhamba ze-ultrasonic zinovelwano kwiprofayili yokuhamba, kwaye ukuchaneka kunokuchaphazeleka kukuhamba okuguquguqukayo okanye okungaguquguqukiyo. Ukulungisa ukuhamba, njengokusebenzisa izilungisi zokuhamba, kudla ngokufuneka ukuqinisekisa ukufundwa okuchanekileyo. Zifumaneka ngobukhulu obahlukeneyo kwaye ziguquguquka ngokubhekiselele ekufakweni.

7.Izicelo

• I-EMF:
  Ilungele ukusetyenziswa kwezinto ezininzi ezisebenzisa ulwelo oluqhuba amanzi njengonyango lwamanzi amdaka, ukucutshungulwa kweekhemikhali, iinkqubo zokusasazwa kwamanzi, kunye nokulinganiswa kodaka.

• I-USM:
  Zilungele zombini ulwelo oluqhuba umbane kunye nolungaqhubi umbane, kuquka ioyile, igesi, amanzi kunye neekhemikhali. Ziluncedo kakhulu kumashishini apho kufuneka khona umlinganiselo ongangenisi mbane, njengakwiinkqubo ze-HVAC, imibhobho yegesi yendalo, kunye nokuthuthwa kweoyile.
