Kuiswa kwe clamp-on ultrasonic flowmeter ndiyo iri nyore uye iri nyore kupfuura mamwe ese flow metres, chero bedzi ukasarudza nzvimbo yekuyera yakakodzera, isa ma parameter epombi panzvimbo yekuyera mu flowmeter, wobva waisa probe papombi. Kuti uve nechokwadi chekuti kuyera kwakarurama, misimboti inotevera inofanirwa kuteverwa:
1. Sarudza chikamu chepombi chakazadzwa nemvura, zvinhu zvakafanana uye zviri nyore kushandisa ultrasonic transmission, senge chikamu chepombi yakamira kana chikamu chepombi yakatwasuka.
2. Nzvimbo yekuisa inofanira kunge iri kure zvachose nezvinhu zvinokanganisa zvakaita semavharuvhu, mapombi, magadzirirwo emagetsi ane simba rakawanda uye mafrequency converters.
3. Dzivisa kuisa panzvimbo yakakwirira yehurongwa hwemapaipi kana pamapaipi akamira ane nzira dzekubuda nadzo dzakasununguka.
4. Tembiricha nekumanikidzwa panzvimbo yekuyera zvinofanira kunge zviri mukati menzvimbo yekushanda yesensor.
5. Masensa maviri e ultrasonic flowmeter anofanira kuiswa munzira yakatwasuka ye axial pamusoro pe pombi, uye kuiswa mukati me ±45° yenzvimbo yakatwasuka ye axis kudzivirira chiitiko chemapombi asina kugutsikana, mabubbles kana mvura muchikamu chepamusoro, zvichikanganisa kuyerwa kwakajairika kwesensa.
Pamusoro penzira dzekudzivirira dzataurwa pamusoro apa, flowmeter yekunze ine clamped ultrasonic inofanira kugara ichichengetwa mushure mekuiswa, zvakaita sekutarisa nguva dzose kana transducer yakasununguka, kutarisa kana namatidza iri pakati pepombi yakanaka, nezvimwewo, kuve nechokwadi chekuti flowmeter ye ultrasonic inoshanda kwenguva refu.
