Ma flowmeter e ultrasonic anogona kuyera mwero mudiki wekuyerera kwemvura, asi mhedzisiro yekuyera inosiyana zvichienderana nemhando dzakasiyana dze flowmeters uye mamiriro chaiwo ekushandiswa.

Ma flowmeter e ultrasonic anogona kuyera mwero midiki yekuyerera, asi mhedzisiro yekuyera inosiyana zvichienderana nemhando dzakasiyana dze flowmeters uye mamiriro chaiwo ekushandiswa. Kutanga, kugona kwenheyo ye ultrasonic flowmeter ndeyekuverenga mwero wekuyerera nekuona musiyano wenguva uye shanduko ye frequency ye ultrasonic wave iri kupararira mumvura. Zvinogoneka pachiyero chekuyera kuyerera kudiki. Ultrasonic flowmeter ye ultrasonic musiyano: Pfungwa ndeyekuyera musiyano wenguva wekupararira kwe ultrasonic munzira yekukwira nekukwira, kuitira kuverenga kumhanya kwemvura uye mwero wekuyerera. Kune traffic diki, kunyangwe musiyano wenguva ungave mudiki kwazvo, kuburikidza ne tekinoroji yekuyera nguva chaiyo uye ma signal processing algorithms, shanduko dzenguva diki dzinogona kuonekwa, uye ipapo mwero wekuyerera kudiki kunogona kuverengerwa. Semuenzaniso, mamwe ma ultrasonic flowmeters e high-precision time-difference anogona kuyera mwero midiki yekuyerera yakaderera se ml/min shoma. Murabhoritari, michina yekurapa nedzimwe nzvimbo, kuti kuyeresa kwakarurama kwezvinodiwa zvekuyerera kudiki kwakakwira, nzira yekusiyana kwenguva ye ultrasonic flowmeter inogona kusangana nezvinodiwa izvi. Doppler ultrasonic flowmeter: Zvichienderana neDoppler effect, mwero wekuyerera uye mwero wekuyerera kwemvura zvinoonekwa nekuyera kushanduka kwemafungu eultrasonic akapararira mumvura. Kune mvura ine zvidimbu zvidiki kana mabubbles, kunyangwe mwero wekuyerera uri mudiki, zvidimbu izvi kana mabubbles zvinogona kukonzera kupararira kwemafungu eultrasonic, kuitira kuti mwero wekuyerera kudiki ugone kuyerwa nenzira yeDoppler. Semuenzaniso, mune dzimwe nzvimbo dzezvekurapa, pakuyera masero ane mvura kana zvidimbu zvidiki, Doppler ultrasonic flowmeters inogona kuita basa. Kunyangwe ultrasonic flowmeters ichigona kuyera mwero wekuyerera kudiki, ichiri kutarisana nematambudziko mukushandiswa kwayo. Simba rechiratidzo uye mwero wechiratidzo-ku-ruzha: Kune mwero wekuyerera kudiki, kupararira kwezviratidzo zveultrasonic mumvura kunogona kudzikira zvakanyanya, zvichikonzera simba rechiratidzo risina simba. Panguva imwe chete, nekuda kwekuvapo kweruzha rwekumashure, mwero wechiratidzo-ku-ruzha unogona kudzikiswa, zvichikanganisa kururama kwekuyera. Semuenzaniso, mune dzimwe nzvimbo diki dzekuyera kuyerera, masensa ane hunhu hwepamusoro uye tekinoroji yepamusoro yekugadzirisa masaini zvinodiwa kuti kuvandudza simba remasaini uye chiyero chechiratidzo-kune-ruzha kuve nechokwadi chekuvimbika kwekuyera. Hunhu hwemvura, senge viscosity, density, tembiricha, nezvimwewo, hune simba guru pakumhanya kwekupararira uye kuderera kwewave ye ultrasonic. Mukuyera kuyerera kudiki, shanduko idzi muhunhu hwemvura dzinogona kuve dzakakosha, zvichikanganisa kurongeka kwekuyera. Semuenzaniso, kune mvura ine viscosity yakawanda, kumhanya kwekupararira kwewave ye ultrasonic kuchanonoka uye dhigirii yekuderera kuchawedzerwa, uye calibration yakakosha uye muripo we flow meter zvinogona kudiwa kuti zvienderane nehunhu hwakasiyana hwemvura. Mamiriro ekuisa uye ekushandisa: Zvinhu zvakaita senzvimbo yekuisa ye ultrasonic flowmeter, mamiriro epaipi, uye nzira yekuisa ye sensor zvichakanganisawo mhedzisiro yekuyera kwe small flow rate. Semuenzaniso, kuiswa munzvimbo refu yechikamu chepombi yakatwasuka kunogona kuve nechokwadi chekugadzikana kwekuyerera kwemvura uye kuvandudza kurongeka kwekuyera; Angle yekuisa uye daro re sensor zvinodawo kugadziriswa zvichienderana nemamiriro chaiwo kuti uwane mhedzisiro yakanakisa yekuyera. Pamusoro pezvo, mukushandiswa kwayo, zvakakosha kungwarira kudzivirira kukanganiswa kwekunze, senge kukanganiswa kwemagetsi, kudedera, nezvimwewo, zvinhu izvi zvinogona kukanganisa mashandiro akajairika e flow meter, zvichikonzera kuwedzera kwezvikanganiso zvekuyera. Mukupfupisa, ultrasonic flowmeters inogona kuyera kuyerera kudiki, asi zvakakosha kusarudza mhando ye flowmeter yakakodzera zvichienderana nemamiriro chaiwo ekushandisa, uye kungwarira kugadzirisa dambudziko resimba rechiratidzo, hunhu hwemvura uye mamiriro ekuisa uye ekushandisa kuti ive nechokwadi chekuti kuyera kwakarurama uye kwakavimbika.
