Iimitha zokuhamba kwe-Doppler ultrasonicziye zaba sisixhobo esibalulekileyo kwi-fluidumlinganiselo wokuhamba kwamanzikumashishini ahlukeneyo. Umgaqo wabo okhethekileyo wokusebenza, osekelwe kwisiphumo seDoppler, ubanika iimpawu ezahlukeneyo ezibenza bafaneleke kakhulu kwiintlobo ngeentlobo zezicelo.

2. Umlinganiselo Ongangeneleliyo

Enye yezona zinto zibalaseleyo zeIimitha zokuhamba kwe-Doppler ultrasonicyindlela yazo yokungangeneleli. Ii-transducers ze-Ultrasonic zibotshelelwa nje kumphezulu wangaphandle wombhobho. Oku kususa isidingo salo naluphi na ungenelo olubonakalayo kumbhobho okanye ukuphazamiseka kokuhamba kolwelo. Ngenxa yoko, ukufakelwa kukhawuleza kwaye kulula, kudla ngokufuna ixesha elincinci lokungasebenzi. Umzekelo, kwisityalo seekhemikhali apho imibhobho ithwala ulwelo olunokubola kakhulu okanye olunetyhefu, le ndlela yokufaka engangeneleliyo iluncedo kakhulu. Inciphisa umngcipheko wokuvuza kunye nongcoliseko olunokwenzeka ukuba umbhobho ubuvulwa ukuze kufakwe imitha yokuhamba emgceni.

3. Ukusebenza kwiifluids ezinee-particles okanye ii-bubbles ezixhonyiweyo

Iimitha zokuhamba kwe-Doppler ultrasoniczilungele ngokukodwa ukulinganisa ukuhamba kolwelo oluneziqina ezixhonyiweyo okanye amaqamza egesi. Amaza e-ultrasonic akhutshwa yi-transducer abonakaliswa ngala maqamza okanye amaqamza kulwelo. Utshintsho lwe-Doppler kwisantya samaza abonakalisiweyo, olubangelwa kukuhamba kwezinto ezibonakalisayo ngokuhamba kolwelo, luyafunyanwa kwaye lusetyenziswe ukubala isantya solwelo. Oku kuzenza zilungele ukusetyenziswa njengakwizityalo zonyango lwamanzi amdaka, apho amanzi amdaka aqulethe iintlobo ngeentlobo zezinto eziphilayo ezixhonyiweyo kunye namaqamza aqinileyo. Kwishishini leoyile negesi, ngexesha lokuveliswa kweoyile, ulwelo ludla ngokuba namaqamza egesi, kwaye iimitha zokuhamba ze-ultrasonic ze-Doppler zinokulinganisa ngokuchanekileyo isantya sokuhamba kolu lwelo lwezigaba ezininzi.

4. Uluhlu olubanzi lokuhamba kwamanzi

Ezi mitha zokuhamba zinokuphatha uluhlu olubanzi lwamazinga okuhamba. Ziyakwazi ukulinganisa ngokuchanekileyo isantya sokuhamba esiphantsi kakhulu nesiphezulu kakhulu. Olu hlengahlengiso olubanzi lomgama wokuhamba luzenza zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Kwindawo yelabhoratri encinci, apho kufuneka umlinganiselo ochanekileyo wokuhamba kolwelo oluncinci, iimitha zokuhamba ze-Doppler ultrasonic zinokubonelela ngokufundwa okuchanekileyo. Kwelinye icala, kwiinkqubo ezinkulu zoshishino, njengakwizityalo zamandla apho amanzi okanye umphunga omninzi kufuneka ulinganiswe khona, ezi mitha nazo zinokwenza ngokuthembekileyo. Ukukwazi kwazo ukugubungela uluhlu olubanzi lokuhamba ngaphandle kokulahlekelwa kakhulu kukuchaneka yinzuzo enkulu.

5. Impendulo ekhawulezayo

Iimitha zokuhamba kwe-Doppler ultrasonicinika impendulo ekhawulezayo, ebavumela ukuba babone ngokukhawuleza utshintsho ekuhambeni kolwelo. Oku kubalulekile kwizicelo apho ukujonga utshintsho lwesantya sokuhamba ngexesha langempela kubalulekile. Umzekelo, kwinkqubo yokuvelisa apho ukuhamba kwezinto eziluhlaza kufuneka kulawulwe ngokuchanekileyo, naluphi na utshintsho olukhawulezileyo kwisantya sokuhamba kunokubonwa ngoko nangoko yiDoppler ultrasonic flow meter. Oku kuvumela ukuba kwenziwe uhlengahlengiso olukhawulezileyo kwinkqubo, ukuqinisekisa umgangatho wemveliso ohambelanayo kunye nokusebenza ngokufanelekileyo.

6. Akukho Zinto Zishukumayo

Enye inzuzo yee-Doppler ultrasonic flow meters kukuba azinazo iindawo ezihambayo ngaphakathi kwendlela yokuhamba kolwelo. Oku kunciphisa kakhulu umngcipheko wokuguguleka koomatshini, nto leyo exhaphakileyo kwii-flow meter zemveli ezixhomekeke kwizinto ezihambayo ezifana nee-turbines okanye iigiya. Ukuba azinazo iindawo ezihambayo, iimfuno zokugcinwa zincinci, kwaye ixesha lokusetyenziswa kwe-flow meter liyandiswa. Oku kuzenza zibe lukhetho olunexabiso eliphantsi ekuhambeni kwexesha, njengoko kungekho mfuneko yokutshintshwa rhoqo kweendawo ezigugileyo okanye iinkqubo zokugcinwa ezibizayo.

7. Ukumelana neemeko ezinzima

Iimitha zokuhamba kwe-Doppler ultrasonicZenzelwe ukumelana neemeko ezinzima zokusingqongileyo. Zingasebenza kumanqanaba aphezulu obushushu, ukusuka kwiindawo ezibandayo kakhulu kwimisebenzi yeoyile negesi yeArctic ukuya kwiindawo zokushisa eziphezulu kwiifektri zentsimbi okanye kwizityalo zamandla. Ukongeza, zihlala zichasana nokuphazamiseka kwe-electromagnetic, okuxhaphakileyo kwiindawo zoshishino ezineenjini ezininzi zombane, ii-transformers, kunye nezinye izixhobo zombane. Ukwakhiwa kwazo okuqinileyo kunye nendlela yokulinganisa engadibaniyo kuzenza zilungele ukusetyenziswa kwiindawo apho ulwelo olulinganiswayo lunokuba yingozi, njengoko ii-transducers zingadibani ngqo nolwelo.

8. Ukufakwa okulula kunye nokulinganisa

Ukufakelwa kweIimitha zokuhamba kwe-Doppler ultrasonicilula kakhulu. Iitransducers zinokubotshelelwa lula kumbhobho, kwaye kwiimeko ezininzi, akukho zixhobo zikhethekileyo okanye iinkqubo ezintsonkothileyo ezifunekayo. Ukulinganisa ezi flow meter kulula kakhulu. Nje ukuba zifakwe, zinokulinganiswa kusetyenziswa iinkqubo zokulinganisa eziqhelekileyo, kwaye kwezinye iimeko, zinokulinganiswa ngokwazo ngokusekelwe kwiimpawu zolwelo ezaziwayo kunye nejometri yombhobho. Oku kulula kokufakela kunye nokulinganisa kwenza ukuba zifikeleleke kubasebenzisi abaninzi, kwanabo banolwazi oluncinci lobuchwephesha.

Ukuququmbela,Iimitha zokuhamba kwe-Doppler ultrasoniczibonelela ngokudibanisa iimpawu ezenza zibe nokuguquguquka okukhulu kwaye zithembeke ekulinganiseni ukuhamba kolwelo. Indalo yazo yokungaphazamisi, ukukwazi ukuphatha ulwelo ngezinto ezixhonyiweyo, uluhlu olubanzi lokuhamba kolwelo, impendulo yesantya esiphezulu, ukungabikho kweendawo ezihambayo, ukumelana neendawo ezinzima, kunye nokufakwa okulula kunye nokulinganiswa kwenza ukuba zibe lukhetho olukhethwayo kwizicelo ezininzi zoshishino, okusingqongileyo, kunye nezenzululwazi.
