Pakuyera kuyerera kwepombi, ma clamp-on ultrasonic flow meter anonyanya kufarirwa nekuti haapindiri uye ari nyore kuisa. Zvisinei, chimwe chinhu chakakosha pakushandisa ma flow meter aya chinowanzo furatirwa - kudiwa kwekuaputira ne coupling agent. Mublog rino, tichaongorora kuti sei clip-on ultrasonic flow meter coatings ne couplant zvichikosha pakuyera kwakarurama uye kwakavimbika.
Chekutanga, zvakakosha kunzwisisa kuti clamp-on ultrasonic flowmeter inoshanda sei. Midziyo iyi inoshandisa mafungu e ultrasonic kuyera kuyerera kwemvura mumapaipi. Sensor ye flow meter yakasungirirwa kunze kwepaipi, uye chiratidzo che ultrasonic chinotumirwa kuburikidza nemadziro epaipi chichipinda mumvura inoyerera. Sensor iri kune rimwe divi repaipi inobva yagamuchira chiratidzo uye inoverenga flow rate zvichienderana nenguva inotora kuti chiratidzo chifambe pakati pemasensa.
Panguva ino, basa remushonga wekubatanidza rinotanga kushanda. Usati wabata sensor papombi, mushonga wekubatanidza (kazhinji gel kana paste) unoiswa pamusoro pe sensor. Mushonga uyu unoshanda senzira yekufambisa, zvichiwedzera kutapurirana kwemasaini e ultrasonic pakati pe transducer nemadziro echubhu. Pasina musanganiswa, mukaha wemhepo uchavapo pakati pe sensor nepaipi, izvo zvinogona kukonzera kurasikirwa kwechiratidzo uye kuyerwa kusina kururama.
Pamusoro pezvo, couplant inobatsira kubvisa chero kusarongeka kwepamusoro kana kusakwana mumadziro echubhu izvo zvinogona kukanganisa kutapurirana kwechiratidzo cheultrasonic. Nekupa kubatana kwakanaka uye kwakaringana pakati pe transducer nepombi, couplant inoita kuti mafungu e ultrasound agone kupfuura nepamadziro epombi uye kupinda mumvura inoyerera pasina chinomutadzisa.
Chimwe chikonzero chakakosha nei ma clamp-on ultrasonic flowmeters akafukidzwa ne couplant ndechekuvandudza mashandiro ese uye hupenyu hwebasa re flowmeter. Coupling agent inoshanda sechidziviriro, ichidzivirira sensor kubva kune zvimwe zvinhu zvakaita sehunyoro, guruva, uye ngura. Izvi zvakakosha zvikuru munzvimbo dzemaindasitiri, uko ma flowmeters anogona kusangana nemamiriro ezvinhu akaoma anogona kukanganisa mashandiro awo nekufamba kwenguva.
Pamusoro pezvinhu zvehunyanzvi, kushandiswa kwe couplant kunorerutsawo maitiro ekuisa clamp-on ultrasonic flow metres. Nekuona kuti pave nekubatana kwakachengeteka pakati pe sensor nepombi, couplant inoderedza njodzi yekutsvedza kana kusarongeka panguva yekuisa, zvichichengetedza nguva nesimba remushandisi.
Muchidimbu, kuputira bhatiri remagetsi rinobata jira remagetsi nechinhu chinosanganisa jira (coupling agent) idanho rakakosha pakuona kuti kuyerwa kwemvura kwakarurama, kwakavimbika uye kwakasimba. Kubva pakuwedzera kutapurirana kwemasaini emagetsi kusvika pakudzivirira masensa, bhatiri rine basa rakakosha mukushanda kwema flow metres aya. Nokudaro, vashandi nenyanzvi vanofanirwa kuziva kukosha kwekushandisa bhatiri uye kutevedzera nzira dzakakodzera dzekushandisa kuti vawedzere kushanda kwema flow metres emagetsi anobata jira remagetsi mumabasa akasiyana-siyana emaindasitiri neemabhizinesi.
