Ndezvipi Zvinwiwa Zvakakodzera Clamp-On Doppler Flowmeters?

Mapombi ekufambisa mvura eClamp-on Dopplerdzakakodzera chete zvinwiwa zvine huwandu hwakati hwezvinwiwa zvinoparadzira acoustic, zvichienderana nepfungwa yeDoppler effect yekuyera kumhanya kwekuyerera nekuona mafambiro emafungu eruzha anoonekwa nezvinwiwa zvinoparadzira (semuenzaniso, zvidimbu, mabubbles) mumvura. Pazasi pane mhando dzemvura chaiyo nemamiriro ezvinhu akakosha ekushandiswa kwadzo:

Mhando dzeLiquid Dzakakodzera dzeCore
1. Zvinwiwa Zvine Zvidimbu Zvakasimba
Midhiya Yakajairika:
Tsvina, tsvina, simbi yemugodhi, simbi yepepa, mvura yakasviba yemumaindasitiri (ine zvidimbu zvakaita sedota, marara, fibers, kazhinji zvine saizi yezvidimbu ≥30 μm).
Zvinwiwa zvine zvidimbu muindasitiri yezvekudya (semuenzaniso, muto wemichero une pulp, masosi, zvinwiwa zvine zviyo).
Zvimisikidzo muindasitiri yemakemikari (semuenzaniso, musanganiswa wezvimedu zve catalyst, slurry ye pigment).
Zvinodiwa Zvikuru:
Kuwanda kwezvikamu kunofanirwa kunge kuri ≥100 ppm kuti zvive nechokwadi chekuti masaini ekuratidza acoustic akakwana.
Kupindirana kweacoustic kwezvikamu kunofanira kusiyana zvakanyanya nekwemvura (semuenzaniso, zvikamu zvakasimba zvinoratidza mhedzisiro iri nani yekuratidzira nekuda kwekusiyana kukuru kwekupindana kwezvikamu nemvura).
2. Zvinwiwa zvine mabhurumu
Midhiya Yakajairika:
Kuyerera kwegasi-mvura ine zvikamu zviviri (semuenzaniso, mvura inoshandiswa muindasitiri ine mabubble emhepo, mvura inoshandiswa pakuvirisa doro).
Zvinwiwa zvakasanganiswa kana kuti zvinofefetedza mweya (semuenzaniso, tsvina inobva mumatangi emhepo inofefetedza mvura yakasviba).
Zvaunofanira Kufunga nezvazvo:
Mabhubhu anofanira kuparadzirwa zvakaenzana mumvura, kudzivirira "magasi akawanda" kana gasi rakawandisa (izvo zvinogona kukonzera kupararira kwechiratidzo chisina kugadzikana).
3. Mvura ine turbid kana kuti isina kujeka
Zviitiko Zvakajairika:
Mvura ine nzira dzekuyera nadzo (semuenzaniso, magineti flowmeters) haishande zvakanaka nekuda kwekusapinda zvakanaka kwemvura (semuenzaniso, mishonga yemakemikari ine ruvara rwakasviba, mvura ine matope).
Zvinonhuwirira kana zvinosanganiswa muindasitiri yezvekudya (semuenzaniso, muto wechokoreti, mafuta anosanganiswa).
