Miyero yekuyedza hunhu hwema ultrasonic flowmeters inonyanya kusanganisira zvinhu zvinotevera: Zviratidzo zvekushanda: Kururama kwekuyera: Mamiriro akasiyana ekushandiswa uye mazinga ekururama ema ultrasonic flowmeters ane zvinodiwa zvekururama zvinoenderana. Semuenzaniso, mune mamwe mashandisirwo akajairika emaindasitiri, kururama kunogona kuva pakati pe ± 1% ne ± 2%; Kune mamwe mashandisirwo ekuyera anonyanya kuoma, kururama kungada kusvika ± 0.5% kana kutopfuura. Mukuona, kuburikidza nekuyedza kwekuenzanisa nemudziyo wekuyerera wakajairika, verenga kukanganisa pakati pemutengo wakayerwa uye kukosha kwakajairika, uye tonga kana kuchizadzisa zvinodiwa zvekururama. Kudzokorora: kunoratidza kuenderana kwemhedzisiro kana flowmeter ichiyera mwero wekuyerera wakafanana kakawanda pasi pemamiriro akafanana. Kukanganisa kwekudzokorora kunowanzo kuve mukati meimwe nzvimbo inobvumidzwa, senge kusapfuura ± 0.2% yemutengo wakayerwa, nezvimwewo, kukosha kwacho kunoenderana nezvinodiwa zve flow meter. Linearity: Dhigirii rehukama hwakatsetseka pakati pechiratidzo chekubuda kwe flowmeter uye mwero wekuyerera. Zvakanaka, kubuda kwe flowmeter kunofanira kunge kune hukama hwakasimba hwemutsara nemwero wekuyerera, asi mukuita pachava nekutsauka kwakati. Kuonekwa kwemutsara kunowanzoonekwa nekuyera panzvimbo dzakasiyana dzekuyerera uye wobva waongorora kutsauka kwehuwandu hwakayerwa kubva pahukama hwemutsara hwedzidziso. Range ratio: Chiyero chehuwandu hwehuwandu hwekuyerera kusvika pahuwandu hwehuwandu hwekuyerera hunogona kuyera flowmeter nemazvo. Range ratio yakakura, ndipo panowanikwa huwandu hwakawanda hwekushandisa kweflowmeter. Kazhinji, range ratio ye ultrasonic flowmeters inofanira kusangana nezvinodiwa zvekushandisa, uye common range ratio ndeye 10:1 kusvika 100:1 kana kupfuura. Hunhu hwechiratidzo: Simba rechiratidzo: Chiratidzo che ultrasonic chinogamuchirwa ne sensor chinofanira kunge chakasimba zvakakwana kuti chive nechokwadi chekuti chiyero chakarurama uye chakagadzikana. Pakuona, kukosha kwesimba rechiratidzo kunogona kuonekwa kuburikidza ne display interface ye flowmeter kana michina yekuona yakakodzera, uye simba rechiratidzo rinowanzo fanirwa kunge riri pamusoro peimwe threshold, senge Q value (signal quality index) yakakura kupfuura kana yakaenzana ne 85. Kugadzikana kwechiratidzo: Munguva yekuyera, ultrasonic signal inofanira kunge yakagadzikana, uye hapafanirwe kuve nekuchinja kukuru kana kukanganiswa kwepakati nepakati. Kugadzikana kwechiratidzo kunoongororwa nekuona shanduko yechiratidzo kwenguva yakareba yekuyera kunoramba kuripo. Kushanda kwemubhadharo wekupisa nekumanikidzwa: Kana muchina wekuyeresa mvura uchiita basa rekuyeresa kupisa nekumanikidzwa, kushanda kwemuchina uyu kunofanira kuyedzwa. Pasi pemamiriro akasiyana ekupisa nekumanikidzwa, muchina wekuyeresa mvura unofanirwa kukwanisa kuzadzisa zvabuda pakuyera, kuitira kuti kukosha kwekuyerera kwemvura kusvike padyo nechiyero chaicho chekuyerera kwemvura. Semuenzaniso, munzvimbo ine shanduko huru dzekupisa, kukanganisa kwemubhadharo wekupisa kwemuchina wekuyeresa mvura kunofanira kunge kuri mukati mechikamu chakatarwa. Kushanda kwemagetsi: Kugona kuchinjika kwesimba remagetsi: Muchina wekuyeresa mvura unofanirwa kukwanisa kushanda zvakajairika mukati memagetsi akasarudzwa uye frequency range. Semuenzaniso, kune muchina wekuyeresa mvura unoshanda neAC, kana magetsi emagetsi achichinja ±10% uye frequency ichichinja ±5%, muchina wekuyeresa mvura unofanirwa kukwanisa kushanda zvakajairika uye mhedzisiro yekuyera haifanirwe kukanganiswa zvakanyanya. Kudzivirira kwekudzivirira: Kudzivirira kwekudzivirira kwemvura pakati pechikamu chemagetsi chemuchina wekuyeresa mvura nekumba kunofanirwa kusangana nezvinodiwa zvekuchengetedza, uye kudzivirira kwekudzivirira kwemvura kunowanzo fanirwa kunge kwakakura kupfuura kukosha kwakati, senge 100MΩ, kuve nechokwadi chekuchengetedzwa panguva yekushandiswa. Kugona Kudzivisa Kukanganiswa: Muchina wekuyeresa mvura unofanirwa kunge uine mukana wekudzivirira magetsi, kukanganiswa kwema frequency eredhiyo nezvimwe zvinhu. Kana paine nzvimbo dzekunze dzinokanganisa, mhedzisiro yekuyeresa mvura haifanirwe kukanganiswa zvakanyanya. Kururama kwekuyera uye kugadzikana kwemuchina wekuyeresa mvura kunogona kuongororwa nekuyedza munzvimbo inotevedzera kukanganiswa. Zvinodiwa pakugadzira michina nekuisa: Kuongorora chitarisiko: goko remuchina wekuyeresa mvura harifanirwe kunge risina mavanga, kushanduka, kuputika nezvimwe zvinhu zvisina kunaka, kufukidza kwepamusoro kunofanirwa kunge kwakafanana uye kwakasimba, uye kuzivikanwa nepepa rezita zvinofanira kunge zvakajeka uye zvichiverengwa. Kuisa masensa: Nzvimbo yekuisa sensor inofanira kusangana nezvinodiwa zvekugadzira, kubatana nepaipi kunofanirwa kunge kwakasimba uye kwakavharwa, uye Angle yekuisa nekutungamira kwesensa zvinofanira kunge zvakarurama kuti ive nechokwadi chekuti zviratidzo zve ultrasonic zvinotumirwa zvakanaka. Semuenzaniso, paunenge uchiisa sensor papombi yakatwasuka, iva nechokwadi chekuti sensor yakatarisana ne axis yepombi; Paunoisa papombi yakatwasuka, nzvimbo yakakodzera yekuisa inofanira kusarudzwa zvichienderana negwara remvura. Dziviriro: Kana flow meter ikashandiswa munzvimbo dzakaoma, dzakadai sehunyoro, guruva, gasi rinoparadza nedzimwe nzvimbo, dziviriro yayo inofanira kuzadzisa zvinodiwa, uye inogona kudzivirira kukuvara kwenzvimbo yekunze kune flow meter. Mamiriro ekugadzirisa: flow standard device: flow standard device inoshandiswa kuona ultrasonic flowmeter inofanira kunge iine chitupa chekusimbisa, uye kusava nechokwadi kwemhedzisiro yekuyera hakufanirwe kupfuura 1/3 yehuwandu hwepamusoro hwekukanganisa hunobvumidzwa hweflowmeter hunofanirwa kuonekwa. Flow standard devices inogona kuva mhando dzakasiyana dzemidziyo senge mass method, volume method kana standard table method. Fluid yekusimbisa: Fluid inoshandiswa pakusimbisa inofanira kunge iri single-phase gas kana liquid, yakazadzwa ne test pipeline, uye flow inofanira kunge isina vortices, serial particles, fibers nezvimwe zvinhu. Kune liquid flowmeter, liquid inofanira kunge yakakwira kupfuura saturated vapor pressure yayo, uye tembiricha, pressure nezvimwe zvinofanirwa kuzadzisa zvinodiwa; Kune gas flowmeter, pressure, tembiricha, uye composition yegasi inofanirawo kuzadzisa mamiriro akakodzera. Mamiriro ekunze: Tembiricha, hunyoro uye kumanikidzwa kwemhepo munzvimbo yekuongorora zvinofanirwa kunge zviri mukati mehuwandu hwakatarwa kuti zvive nechokwadi chekuti mhinduro dzebvunzo dzakarurama. Semuenzaniso, tembiricha yemhepo inowanzova 5 ° C kusvika 45 ° C, hunyoro hwemhepo hunenge 35% kusvika 95% RH, uye kumanikidzwa kwemhepo kunenge 86kPa kusvika 106kPa.
