1. Mhedzisiro yekumusoro uye yakadzika yakatwasuka pombi segment pachiyero chechiyero che ultrasonic flowmeter.Iyo calibration coefficient K ibasa reReynolds nhamba.Kana kuyerera kwevelocity kusina kuenzana kubva pakuyerera kwelaminar kuenda kune mhirizhonga inoyerera, iyo calibration coefficient K ichachinja zvakanyanya, zvichikonzera kudzikira kwechiyero chechiyero.Zvinoenderana nezvinodiwa zvekushandisa, iyo ultrasonic inoyerera mita transducer inofanirwa kuiswa mukumusoro yakatwasuka pombi chikamu che10D, yakadzika yakatwasuka pombi chikamu che5D chinzvimbo, yekukwira kumusoro kwepombi, mavharuvhu uye zvimwe midziyo kana kureba kweyakatwasuka. chikamu chepombi, zvinodikanwa zve "kure kubva kumhirizhonga, kuzunguzika, kupisa sosi, ruzha kunobva uye ray sosi kusvika pazvinobvira".Kana paine pombi, mavharuvhu uye zvimwe midziyo kumusoro kwenzvimbo yekumisikidza yeiyo ultrasonic kuyerera kwemamita transducer, iyo yakatwasuka pombi chikamu chinodiwa kuti ive inodarika 30D.Nokudaro, kureba kwechikamu chepombi chakananga ndicho chinhu chikuru chekuvimbisa kurongeka kwechiyero.
2. Kufuridzirwa kwepipeline parameter midziyo pachiyero chekuenzanisa kwe ultrasonic flowmeter.Iko kurongeka kwepipeline parameter kuseta kwakabatana zvakanyanya nekuyerwa kwechiyero.Kana kuiswa kwezvinhu uye saizi yepombi isingaenderane neiyo chaiyo, zvinokonzeresa kukanganisa pakati peiyo theoretical pipeline inoyerera ichiyambuka-sectional nzvimbo uye chaiyo inoyerera muchinjiko-chikamu nharaunda, zvichikonzera isina kururama yekupedzisira mhedzisiro.Uye zvakare, iyo emission spacing pakati peiyo ultrasonic kuyerera mita transducer mhedzisiro yekuverenga kwakazara kweakasiyana paramita senge fluid (sound velocity, dynamic viscosity), pombi (zvinhu uye saizi), uye nzira yekuisa yetransducer, nezvimwe. uye chinhambwe chekuisa chetransducer chinotsauka, izvo zvichakonzerawo kukanganisa kukuru kwekuyera.Pakati pavo, kugadzika uye kugadzika kureba kwemukati warp yepombi ine simba rakakurumbira pakuyera kwechiyero.Zvinoenderana nedata rakakodzera, kana iyo yemukati longitude kukanganisa kwepombi iri ± 1%, inokonzeresa nezve ± 3% yekuyerera kukanganisa;Kana iyo yekumisikidza kureba kukanganisa iri ± 1mm, iyo yekuyerera kukanganisa ichave mukati ± 1%.Zvinogona kuoneka kuti chete nekumisikidzwa kwakaringana kwepombi paramita kunogona kuisirwa ultrasonic flowmeter nemazvo uye pesvedzero yepipeline paramita pakuyera kwechiyero inogona kuderedzwa.
3, pesvedzero ye ultrasonic kuyerera mita transducer yekuisa chinzvimbo pane kuyerwa kwechokwadi.Pane nzira mbiri dzekuisa iyo transducer: kuratidza mhando uye yakananga mhando.Kana kushandiswa kwekufambisa kwakananga kukwirisa ruzha kuri kupfupi, simba rechiratidzo rinogona kuvandudzwa.
4. Pesvedzero yekubatanidza mumiririri pakuyera kuyerwa.Kuti uve nechokwadi chekusangana kwakazara nepombi, paunenge uchiisa transducer, dhizaini yekubatanidza mumiriri inoda kupfekedzwa zvakaenzana pamusoro pepombi, uye ukobvu hwese huri (2mm - 3mm).Mabhubhu nemagranules ari mucoupler anobviswa kuitira kuti emitter surface yetransducer inonamirwa pamadziro echubhu.Flowmeters yekuyera mvura inotenderera inoiswa zvakanyanya muWells, uye nharaunda ine hunyoro uye dzimwe nguva yakazara.Kana iyo general coupling agent ikashandiswa, inokundikana munguva pfupi, inokanganisa kuyerwa kwechiyero.Naizvozvo, yakasarudzika isina mvura coupler inofanira kusarudzwa, uye coupler inofanira kushandiswa mukati menguva inoshanda, kazhinji mwedzi 18.Kuti ive nechokwadi chekuyera chokwadi, transducer inofanirwa kudzoserwa mwedzi gumi nemisere yega yega uye iyo coupler inofanira kutsiviwa.
