Uma kulinganiswa ukugeleza kwepayipi, amamitha okugeleza e-ultrasonic aqinisiwe ayisinqumo esithandwayo ngoba awaphazamisi futhi kulula ukuwafaka. Kodwa-ke, isici esisodwa esibalulekile sokusebenzisa la mamitha okugeleza sivame ukunganakwa - isidingo sokuwafaka i-coupling agent. Kule bhulogi, sizohlola ukuthi kungani izembozo zemitha yokugeleza ye-ultrasonic ezicijile ezine-coupling zibalulekile ekulinganisweni okunembile nokuthembekile.
Okokuqala, kubalulekile ukuqonda ukuthi i-clamp-on ultrasonic flowmeter isebenza kanjani. Lawa madivayisi asebenzisa amagagasi e-ultrasonic ukukala ukugeleza koketshezi emapayipini. Inzwa ye-flow meter iboshelwe ngaphandle kwepayipi, bese isignali ye-ultrasonic idluliselwa ngodonga lwepayipi iye oketshezini olugelezayo. Inzwa ngakolunye uhlangothi lwepayipi bese ithola isignali bese ibala izinga lokugeleza ngokusekelwe esikhathini esithathayo ukuze isignali ihambe phakathi kwezinzwa.
Ngalesi sikhathi, indima ye-coupling agent iyaqala ukusebenza. Ngaphambi kokubopha i-sensor epayipini, i-coupling agent (ngokuvamile i-gel noma i-paste) ifakwa ebusweni be-sensor. Le coupling isebenza njengendlela yokuxhumana, ithuthukisa ukudluliselwa kwezimpawu ze-ultrasonic phakathi kwe-transducer nodonga lwe-tube. Ngaphandle kwe-coupling, kuzovela igebe lomoya phakathi kwe-sensor nepayipi, okungabangela ukulahlekelwa kwesignali kanye nokulinganisa okunganembile.
Ngaphezu kwalokho, i-couplant isiza ekususeni noma yikuphi ukungahambi kahle noma ukungapheleli kobuso odongeni lweshubhu okungase kuphazamise ukudluliswa kwesignali ye-ultrasonic. Ngokuhlinzeka ngesixhumanisi esibushelelezi nesihambisanayo phakathi kwe-transducer nepayipi, i-couplant iqinisekisa ukuthi amagagasi e-ultrasound angadlula odongeni lwepayipi futhi angene oketshezini olugelezayo ngaphandle kwesithiyo.
Esinye isizathu esibalulekile sokuthi ama-flowmeter e-ultrasonic afakwe i-clamp-on ambozwe nge-couplant ukuthuthukisa ukusebenza okuphelele kanye nokuphila kwenkonzo ye-flowmeter. I-coupling agent isebenza njengesivikelo esivikelayo, ivikela inzwa ezintweni zangaphandle ezifana nomswakama, uthuli, kanye nokugqwala. Lokhu kubaluleke kakhulu ezindaweni zezimboni, lapho ama-flowmeter angase abhekane nezimo ezinzima ezingase zonakalise ukusebenza kwawo ngokuhamba kwesikhathi.
Ngaphezu kwezici zobuchwepheshe, ukusetshenziswa kwe-couplant kwenza kube lula nenqubo yokufaka amamitha okugeleza e-ultrasonic aqiniswayo. Ngokuqinisekisa ukuhlangana okuphephile nokuvikelekile phakathi kwenzwa nepayipi, i-couplant inciphisa ingozi yokushelela noma ukungahleleki kahle ngesikhathi sokufakwa, okusindisa isikhathi nomzamo womqhubi.
Ngamafuphi, ukumboza i-flowmeter ye-ultrasonic ebambekayo nge-ejenti yokuhlanganisa kuyisinyathelo esibalulekile ekuqinisekiseni ukulinganiswa kokugeleza okunembile, okuthembekile nokuhlala isikhathi eside. Kusukela ekuthuthukiseni ukudluliselwa kwezimpawu ze-ultrasonic kuya ekuhlinzekeni ukuvikelwa kwezinzwa, i-couplant idlala indima ebalulekile ekusebenzeni okuphelele kwalawa mamitha okugeleza. Ngakho-ke, opharetha kanye nochwepheshe kumele baqaphele ukubaluleka kokusebenzisa i-couplant futhi balandele izinqubo ezifanele zokusebenzisa ukuze bandise ukusebenza kahle kwamamitha okugeleza e-ultrasonic ebambekayo ezinhlotsheni ezahlukahlukene zezimboni nezentengiselwano.
