I-flowmeter ye-ultrasonic ephathekayo iwuhlobo lwe-flowmeter ye-ultrasonic.I-Flowmeter ye-Ultrasonic iyi-flowmeter esebenza ngokuhluka kwesikhathi se-ultrasonic kanye nemodi ye-Doppler, ngoba ukunemba kokulinganisa ukugeleza kwe-flowmeter ye-ultrasonic cishe kuzimele ekushiseni nokucindezela kokugeleza okulinganiswayo.I-viscosity, ukuminyana namanye amapharamitha, futhi ingenziwa ibe amathuluzi okulinganisa angathinteki futhi aphathekayo, ngakho-ke ingakwazi ukuxazulula ezinye izinkinga zokulinganisa ukugeleza okuqinile njengokugqwala okuqinile, okungeyona e-conductive, okukhipha imisebe kanye nemithombo evuthayo kanye neziqhumane.Izinhlobo zezinsimbi.Ukusebenza kwayo okuhlukene kuzuze umusa wabasebenzisi.
1. Umthelela wendawo yokufaka, i-coupler nomugqa wesiginali esilinganisweni
Ama-flowmeters aphathwayo e-ultrasonic ngokuvamile asebenzisa ama-multi-pulse, amasiginali e-broadband, anekhono elithile lokumelana nokuphazanyiswa yi-electromagnetic.Nokho, kukhona amaza aphezulu endaweni yokufaka, ikakhulukazi uma umthombo wokuphazamiseka kokuguqulwa kwemvamisa ungasebenzi ngokugcwele.Ulayini wesignali we-transducer akulula ukuba ube mude kakhulu, futhi intambo ye-coaxial ye-impedance ethize kufanele isetshenziswe, futhi akufanele kube khona ukujoyina ekugcineni naphakathi.I-agent ye-ultrasonic coupling kufanele isetshenziswe ngangokunokwenzeka nge-conductivity yomsindo omuhle futhi akulula ukuxuba nezinto ze-viscous zegesi, njengengilazi yamanzi, i-Vaseline, njll.
2, i-flowmeter ye-ultrasonic ayilinganiswanga kahle
Noma iyiphi i-flowmeter idinga ukuqinisekiswa noma ukulinganisa ngaphambi kokusetshenziswa, futhi ama-flowmeters aphathekayo we-ultrasonic abaluleke kakhulu ngalesi sikhathi.Ngoba imitha yokugeleza ye-ultrasonic ephathekayo ngokuvamile ifakwe amasethi amaningi ama-transducer, afanele ububanzi obuhlukahlukene bamapayipi, isethi ngayinye ye-transducer kanye nenhlanganisela yomsingathi isethi yamamitha okugeleza.Ngakho-ke, uma kuphela i-transducer encane isetshenziselwa ukulinganisa noma ukulinganisa i-flowmeter ye-ultrasonic ephathekayo kudivayisi evamile yokugeleza enobubanzi bepayipi elincane, khona-ke uma i-transducer enkulu isetshenziselwa ukukala ukugeleza ngesikhathi sokusetshenziswa, kulingana nokusebenzisa okungaqinisekisiwe noma I-flowmeter elinganiselwe ngokunemba kokulinganisa okungenakuqinisekiswa.Indlela efanele isekelwe ekusetshenzisweni komsebenzisi njengereferensi, futhi i-flowmeter ye-ultrasonic ephathekayo kufanele ihlolwe noma ilinganiswe ngamapayipi amaningi kumadivayisi ajwayelekile okugeleza anobubanzi obufanayo noma eduze kwepayipi elisetshenzisiwe.Okungenani, kuyadingeka ukuqinisekisa ukuthi isethi ngayinye yezinzwa ezilungiselelwe ngemitha yokugeleza kufanele ilinganiswe.Isitifiketi semitha noma isitifiketi sokulinganiswa sizonikeza isici sokulungisa imitha kumasethi amaningana ezinzwa.Uma usebenzisa isikhathi sokugeleza, qiniseka ukuthi ufaka isici esilungile sokulungisa imitha yesidlulisi esihambisanayo.
3, ukushiyeka nokulinganiselwa kwe-flowmeter ephathekayo ye-ultrasonic
(1) I-flowmeter ye-ultrasonic ephathekayo yendlela yesikhathi sokuhamba ingasetshenziswa kuphela ukuhlanza uketshezi namagesi.
(2) Ama-flowmeters e-Ultrasonic anama-transducer angaphandle angeke asetshenziselwe amapayipi anolwelwesi oluwugqinsi noma ama-scaling, amapayipi aboshiwe endaweni noma aphakanyisiwe, namapayipi anokugqwala okubi kwezindonga zamapayipi.
(3) Ukukhiqizwa kwasekhaya kwamanje kwama-flowmeters e-ultrasonic akhona ngeke asetshenziselwe amapayipi anobubanzi obungaphansi kwe-DN25mm.
(4) Ukuthuthukiswa nokukhiqizwa kwama-flowmeters afuywayo e-ultrasonic kuseyinsakavukela, futhi intengo iphezulu.
Ukulinganisa ukugeleza kuyipharamitha ebalulekile ohlelweni lokukhiqiza lwamabhizinisi, ikakhulukazi emkhakheni wokongiwa kwamandla nokongiwa kwamanzi nokunye ukuvikelwa kwemvelo kuye kwasetshenziswa kakhulu.I-Flowmeter ephathekayo ye-ultrasonic iwuhlobo olusha lwe-flowmeter, ukunethezeka kwayo kanye nomnotho ezinye i-flowmeters azikwazi i-bini.Kodwa-ke, amaphutha amaningi angahleliwe akhiqizwa amathuluzi anjalo adinga ukutadisha nokuxoxisana okuqhubekayo.Isibonelo, izinguquko endaweni yensimu, imvamisa yamandla, ukukala odongeni lwangaphakathi lwepayipi, namabhamuza epayipi kuzodala izinguquko ezithile enanini lephutha lokulinganisa.Ngakho-ke, hlala ufingqa izindlela zokulinganisa ezinembile kusukela ekusebenzeni, kuwumsebenzi wesikhathi eside wokusebenzisa kahle ama-flowmeters aphathwayo we-ultrasonic ukuze adlale indima yawo ephumelelayo.
I-Flowmeter ephathekayo ye-ultrasonic inezici zokufakwa okusheshayo nokusetshenziswa okuguquguqukayo, kodwa kufanele ikwazi kahle indlela enembile uma usebenzisa.Ngemuva kweminyaka yokusebenza kwensimu, kutholakala ukuthi ukusetshenziswa kwe-flowmeters ephathekayo ye-ultrasonic kulula ukunganakwa, ukuhlaziya izimbangela zezinkinga futhi uphakamise izixazululo.
