imitha yokuqukuqela ye-ultrasonic kunye ne-magnetic flow meter

Ultrasonic flowmeter

Izinto eziluncedo kwi-acoustic flowmeter:

1. Umlinganiselo wokuqukuqela ongadibananga

2. Akukho milinganiselo yokuthintela ukuhamba, akukho kulahleka koxinzelelo.

3. Ulwelo olungaqhubekiyo lunokulinganiswa.

4. Uluhlu lwedamitha yombhobho obanzi

5. Amanzi, igesi, ioli, zonke iintlobo zeendaba zinokulinganiswa, intsimi yayo yesicelo ibanzi kakhulu.

Ukungalungi kwe-flowmeter ye-ultrasonic:

1. Kukho izithintelo ezithile ekulinganiseni imidiya yokushisa ephezulu.

2. Iimfuno eziphezulu zobushushu bebala lokuqukuqela.

3. Ubude becandelo lombhobho elithe tye liyafuneka.

I-Electromagnetic flowmeter ineengenelo ezininzi ekuhambeni kolwelo kwaye isetyenziswa kakhulu kumashishini ahlukeneyo.

I-1Akukho zixhobo zokuthintela ukuhamba kumbhobho wokulinganisa, akukho kulahlekelwa kwengcinezelo, kunye neemfuno zecandelo lombhobho ochanekileyo ziphantsi;

2 Ukuchaneka komlinganiselo ophezulu, uzinzo olomeleleyo, amandla okuphazamiseka okuchasana nokungcangcazela;

I-3 Ukulinganisa akuchaphazeli utshintsho kwi-fluid density, viscosity, ukushisa, uxinzelelo kunye ne-conductivity;

I-4 Ngeentlobo ezahlukeneyo ze-electrode kunye neenketho ze-lining, ukuchasana okunamandla kwi-corrosion ye-dielectric.

Ewe kunjalo, ii-electromagnetic flowmeters zinemida yazo:

1 Umlinganiselo wokulinganisa kufuneka ube ne-conductivity ethile (ngokubanzi ngaphezu kwe-5us / cm), kwaye kukho iimfuno ezithile zokulinganisa isantya sokuqala sokuhamba (ngokubanzi ngaphezu kwe-0.5m / s).

I-2 Ubushushu bomgangatho wokulinganisa bukhawulelwe yimpahla ye-lining, kwaye umphumo wokulinganisa weqondo lokushisa eliphezulu awulungile.

3 Ayikwazi ukulinganisa irhasi, umphunga kunye nezinye imidiya.

4 Ukuba i-electrode yokulinganisa isebenza ixesha elide, kunokubakho ukulinganisa, okunokulinganiswa kuphela emva kokucoca.

5 Kwinqanaba eliphezulu le-viscosity medium kunye ne-slid-liquid medium-phase medium, kuyafuneka ukuba kusetyenziswe i-high frequency excitation, i-low frequency low low magnetic ichaneka.

I-6 Ngenxa yokunciphisa umgaqo wesakhiwo senzwa, ixabiso leemveliso ezinkulu ze-caliber ziphezulu kakhulu, ezikhokelela ekwandeni kwemveliso kunye nexabiso.

7 Ngenxa yokulinganiselwa kwayo kwemigaqo, i-coil ye-sensor yesixhobo kufuneka inikwe amandla ukuvelisa indawo yamagnetic, kwaye usetyenziso lwamandla oluqikelelweyo luphezulu, olungafanelanga ukunikezelwa kwamandla ebhetri.

Ukuthelekisa

1. Ukuchaneka kwee-flowmeter zemagneti kuphezulu kune-ultrasonic flowmeter's.

2. Ixabiso le-electromagnetic flowmeter's flowmeters lichaphazeleka ngamadayimitha wombhobho, kodwa i-clamp kwi-ultrasonic flow meter, ixabiso layo alihambelani nobubanzi bombhobho.

3. Imitha yokuqukuqela yeMagentic ayinyanzeli kudidi, imitha yokuhambahamba ye-ultrsonic ayinyanzelekanga ukuba ibambezele, inokufikelela kwiimitha zokuhamba kwamanzi ezingadibanisiyo.

4. Imitha yemitha ye-ultrasonic inokusebenza kunye nolwelo olungaqhubekiyo, njengamanzi acocekileyo.Imitha yokuqukuqela ye-Electromagnetic inokulinganisa ulwelo oluqhubayo.

5. Imitha yokuhamba ye-Eletromagnetic ayinakulinganisa ulwelo oluphezulu kakhulu lobushushu, kodwa imitha yokuqukuqela ye-ultrasonic ilungile kulwelo oluphezulu lobushushu.
