1) Electromagnetic flowmeter inoda pombi yakatwasuka yakapfupika pane ye ultrasonic flowmeter. Nzvimbo yekuisa electromagnetic flowmeter inogona kunge isiri pombi yakatwasuka, saka enzanisa panzvimbo yacho, teerera nzvimbo yekuyera kana ichikwanisa kusangana nezvinodiwa zve straight pipe ultrasonic flowmeter, kana isingasvike pombi yakatwasuka inofanira kunge iri pedyo sarudza inoenderana nenzvimbo yekuyera ultrasonic flowmeter, kuenzanisa mhedzisiro haizove yakarurama.
2) Tarisa kana nzvimbo yekuisa electromagnetic flowmeter ichizadzisa zvinodiwa nekuyerera kwemvura (sekunge kufambisa kwemvura, kana kuiswa kuri munzvimbo yakaderera yepombi, kana mabubbles angaungana, nezvimwewo). Kana zvisiri, zvinofanirwa kutaurwa kumushandisi kuti izvi zvinogona kunge zviri izvo zvakakonzera dambudziko.
3) Electromagnetic flowmeter chishandiso chakanaka chekuyera kuyerera kwemvura inoyerera. Kurongeka kwayo kwekuyera kwakanyanyawo, kazhinji mu0.5%, uye zvakanakisisa kusvika 0.2%. Panguva imwe chete, kutarisisa kunofanira kupihwa kumugadziri weelectromagnetic flowmeter. Kana chigadzirwa chemhando yacho chakaiswa pasina kukanganisa uye mvura inoyerera ichisangana nezvinodiwa, kukosha kwekuyera kunofanirwa kufungidzirwa nokungwarira, nepo kune vagadziri vasiri vemainstream, zvichienderana nekugadzikana kwesimba remagetsi uye saizi yekukanganisa, unogona kuva neushingi hwekusava nechokwadi.
4) Nzwisisa mamiriro epombi, kana paine jira, kukura nezvimwe zvinhu pamwe chete nema parameter ane chekuita nepombi kubva kumushandisi. Polish pombi paunenge uchiisa sensor ye ultrasonic, uye sarudza nzira ye Z yekuyera nekuenzanisa zvakanyanya sezvinobvira.
5) Mvura inogona kuyerwa ne ultrasonic flowmeter haikanganisike ne conductivity. Kana ultrasonic value yakagadzikana nepo electromagnetic value isina kugadzikana panguva yekuenzanisa, zvinoratidza kuti conductivity ye flow body iri kuyerwa iri mu boundary state ye index, kwete inokonzerwa nemvura ine gasi, uye kukosha kwe ultrasonic flowmeter kunovimbika. Kana zvese zvisina kugadzikana panguva imwe chete, mukana wekuti pave nemabubbles wakakura.
6) zvinodiwa zve electromagnetic flowmeter kuti zviyerwe mvura zvinofanirwa kunge zvakaenzana ne earth, zvikasadaro pachava nekupikiswa kwakasimba, saka kana grounding isiriyo kana grounding isina kunaka (electromagnetic grounding ine zvinodiwa zvakaoma uye zvakaoma), pachava nematambudziko, tarisa mamiriro egrounding. Kana tichienzanisa ne ultrasonic flowmeter, hapana chinodiwa che potential ye fluid. Kana grounding iine mubvunzo, kukosha kwe ultrasonic flowmeter kwakarurama.
7) Kana paine kupindirana kwemagetsi nemagineti pedyo, simba re ultrasonic flowmeter harisi pasi pe electromagnetic flowmeter, uye kuvimbika kwe ultrasonic display value kunofanira kunge kwakakura kupfuura electromagnetic flowmeter.
8) Kana paine ruzha runopindira mupaipi (senge ruzha runogadzirwa nevharuvhu hombe inogadzirisa kumanikidzwa), simba re ultrasonic rakakura kupfuura re electromagnetic, uye kuvimbika kwechiratidzo che electromagnetic kwakakura kupfuura kwe ultrasound.
