Moemeli oa ho kopanya o nolofalletsa phetiso e tšepahalang ea maqhubu a ultrasound pakeng tsa transducer le bokaholimo ba lebota la tube. Ho kenya nako e telele (e tsitsitseng) le ho kenya nako e khuts'oane (e tsamaeang) ho lokela ho sebelisa mefuta e fapaneng ea li-coupling. Litšebeliso tsa nako e telele tsa li-coupling ha e le hantle ke li-Araldites le li-epoxy resins tse sa tlatsoang (li-filler li tla hasanya maqhubu a ultrasound). Li-coupling tse tsitsitseng tsa ho kenya tse sa feleng li hloka ho hlahlojoa khafetsa, potoloho ea tlhahlobo e hlalosoa ke moetsi oa sehlahisoa ho latela mofuta oa sona, 'me mosebetsi oa tlhahlobo oa ultrasound flowmeter ka boeona o ka sebelisoa ho hlahloba hore na o lokela ho nkeloa sebaka neng. Moemeli oa ho kopanya oa ts'ebeliso ea nako e khuts'oane o kenyelletsa: grease ea silicone, grease ea axle le tse ling. E le ho netefatsa hore ha li ome, ho khothaletsoa ho ntša coupling ea botenya ba 3 ho isa ho 4mm le bophara ba hoo e ka bang 5mm nako le nako, 'me u e sebelise ho latela axis ea transducer, ebe u e hatella leboteng la tube. Mehato le mehato e latelang ea pele ho kalafo le eona e lokela ho etsoa pele ho lahla coupler:
1. Lebota le ka ntle la pompo moo transducer e kentsweng teng le lokela ho dula le hlwekile mme le se na mafura. Haeba ho na le lesela kapa lera le leng le kwahelang, le tlameha ho tloswa, haholo-holo bakeng sa lera le kwahelang le nang le faeba le letlooeng la tshepe.
2. Ha ho sebetsanwa le lebota la phaephe, ho hlokahala ho boloka moralo wa pele wa sedikadikwe sa phaephe, le ho boloka bokahodimo ba transducer bo bapile le tataiso ya axial ya phaephe, hobane phoso ya degree e le 1 e ka fetola bolelele ba tsela ya acoustic ya 1% ho isa ho 2%.
3. U se ke ua sebelisa coupler ho feta tekano, e lokela ho ba hlokolosi haholo ho thibela ho ata ho feteletseng, ho qoba ho kopanya coupler moeeng.
4. Tikolohong ea lerōle le flocculent, re lokela ho ela hloko haholo ho thibela ho tsoakana ha litšila tse ling, hobane lerōle le flocculent li tla fokotsa phello ea ho kopanya, 'me ho bonolo ho omisa moemeli oa ho kopanya.
5. Haeba ho na le masoba leboteng la tube, sebelisa sesebelisoa se lekaneng sa ho kopanya ho a tlatsa le ho etsa tsela e felletseng ea molumo. Haeba phaephe e le polasetiki, bokaholimo bo penta hanyane ho netefatsa hore sesebelisoa sa ho kopanya se khomarela ka ho lekaneng joalo ka resin ea epoxy.
6. Ela hloko khetho le ts'ebeliso ea sehokelo tlas'a maemo a fapaneng a mocheso, 'me u buisane le mofani oa sehokelo tlas'a maemo a sa tloaelehang a ts'ebetso.
7. Sehokelo se thehilweng metsing se tla fetoha mouoane mochesong o phahameng, se hoame mochesong o tlase mme se fetole litšobotsi tsa sona; Lihokelo tse thehilweng oling li tla phalla mochesong o phahameng, 'me tse ling lihokelo li tla fetola ts'ebetso mochesong o tlase.
8. Maemong a mocheso o tlase (joalo ka oksijene e metsi, naetrojene e metsi, jj.), likarolo tsa ho kopanya tsa letoto la tšepe ea indium li ka khethoa.
9. Maemong a mocheso o phahameng (130C ~ 200C), maqephe a ho kopanya a letoto la tšepe a ka khethoa.
10. Mochesong o phahameng (200C ~ 400C), o ka kgetha karolo ya tshepe ya ho kopanya letoto la silevera.
11. Tikolohong e metsi kapa tikolohong e ka tlas'a metsi, ho ka sebelisoa likotoana tse khethehileng tsa rabara ea maiketsetso.
