Ma flow meters akasiyana-siyana anoshanda mukusimudzira kushanda zvakanaka kwesystem, kururama kwayo, uye kuvimbika kwayo kwenguva refu. Zvakakosha kutarisa zvinhu zvakasiyana-siyana zvemhando imwe neimwe uye kuti zviri kugadzirisa sei zvinodiwa zvikuru mumaindasitiri. Tsvaga rudzi rwe flow meters kuti ienderane nezvinodiwa chaizvo.
Mhando dzeMamita Ekuyerera
Chiyero chekuyerera kwehuwandu
Amita yekuyerera kwehukuru, inozivikanwawo se inertial flow meter, inoshandiswa kuyera huwandu hwemvura inoyerera nemuchubhu. Huremu hwemvura inoyerera ichipfuura nzvimbo yakatarwa panguva imwe neimwe inonzi huwandu hwemvura inoyerera. Iyo mass flow meter inoyera huwandu hwemvura pane huwandu hwemvura inoyerera panguva imwe neimwe (semuenzaniso kgs pasekondi) inotumira nemuchina.
Mita yekuyerera kweCorioliszvinotorwa sema "flow meter" akarurama kwazvo anogona kudzokororwa pari zvino. Anotumira mvura mumachubhu anodedera uye anotarisa shanduko musimba remvura. Mvura inopinda mumachubhu anodedera inokonzera kutenderedza kudiki kana kukanganisika. Kutenderedza kwakadaro nekukanganisika kunoenderana zvakananga nekufamba kwemvura. Coriolis metres inoshanda mune ese ari mavirikuyerwa kwehukuru nekuwanda, zvichishandiswa zvakasiyana-siyana mumabasa akasiyana-siyana akadai semakemikari, mafuta, uye gasi. Kushanda kwavo kwakanaka mukuita kwavo nemazvo uye kushandiswa kwavo kwose kwose ndizvo zvikonzero zvikuru zvinoita kuti vafarirwe mumabasa akaomarara emaindasitiri.
Rudzi rwekuvharirwa
Mita yekuyerera yeDifferential Pressure (DP)zvakagadziridzwa kuti zvienderane nekushanduka-shanduka kwezvinodiwa zveindasitiri yemazuva ano, zvichiramba zviri sarudzo yakavimbika mukutarisa nekuyera kuyerera kwemvura. Musiyano wekumanikidzwa unoyerwa zvichibva papfungwa yekuti hukama hwakati pakati pemusiyano wekumanikidzwa unogadzirwa kana mvura ichiyerera kuburikidza nemidziyo inodhonza mvura uye mwero wekuyerera kwemvura. Mudziyo unodhonza mvura chinhu chemunzvimbo chinoiswa mupayipi. Chinonyanya kushandiswa ndeichimaplate e orifice, maburiuyemachubhu eventuri,iri kushandiswa zvakanyanya mukuyera nekugadzirisa maitiro emaindasitiri.
A mita yenzvimbo inoshandukainoshanda kuburikidza nekuyera kuyerera kwemvura inoyambuka nzvimbo yechikamu chemudziyo kuti isiyane zvichienderana nekuyerera kwayo. Imwe mhedzisiro inoyerwa inoratidza mwero. Rotameter, muenzaniso we variable area meter, inowanikwa kune akasiyana-siyana emvura uye inowanzo shandiswa nemvura kana mhepo. Mumwe muenzaniso i variable area orifice, umo mvura inoyerera ichipinda nepaburi ichatsausa spring-loaded tapered plunger.
Chiyero cheKuyerera kweMutsetse
Iyoturbine flowmeterinoshandura mashandiro emuchina kuita mwero wekuyerera unoverengwa nemushandisi. Sezvakaita gpm, lpm, nezvimwewo. Vhiri returbine rinoiswa munzira yerwizi rwemvura kuitira kuti kuyerera kwese kuri kufamba kwaro. Ipapo mvura inoyerera inopindira pamashizha eturbine, ichigadzira simba pabanga uye ichisundira rotor mukufamba. Kumhanya kweturbine kunoenderana nekumhanya kwemvura kana kumhanya kwakagadzikana kwekutenderera kwasvika.
Chiyereso chemagetsi chemagetsi
Iyochiyereso chemagetsi chinoyerera, inozivikanwawo se "mita yemagi"kana"magetsi", shandisa munda we megnetic wakaiswa pachubhu yekuyera, izvo zvinokonzera mutsauko ungangoitika mukuenderana nekumhanya kwekuyerera kwakatarisana nemitsetse ye flux. Mamita akadaro anoshanda paMutemo waFaraday weElectromagnetic Induction, umo simba remagineti rinoshandiswa mumvura. Ipapo mwero wekuyerera unogona kutsanangurwa ne voltage inoyerwa inobuda. Mhinduro inoshandiswa kumaindasitiri ane mvura yakasviba, inoparadza kana inokuvadza. Nekuda kwekunyatsojeka uye kugara kwenguva refu,mamita ekuyerera kwemaginetianowanzo shandiswa mukurapa mvura, kugadzira makemikari, pamwe nekugadzira chikafu nezvinwiwa.
Anmita yekuyerera kweultrasonicinoyera kumhanya kwemvura ne ultrasound kuti iverenge kuyerera kwehuwandu. Flowmeter inokwanisa kuyera avhareji yekufamba munzira ye ultrasound inoburitswa kuburikidza ne ultrasonic transduces. Verenga mutsauko wenguva yekufamba pakati pe pulses ye ultrasound ichidzika mukati kana kuti ichipesana negwara rekuyerera kana kuyera frequency shift zvichienderana ne Doppler Effect. Pamusoro pe acoustic property yemvura, tembiricha, density, viscosity uye suspended particulates zvimwe zvinhu zvinokanganisa amita yekuyerera kwemvura yakawanda.
Amita yekuyerera kwemhepoinoshanda papfungwa yekuti "von Kármán vortex", ichitarisa mwero wekuyerera kwemvura nekuyera mwero wekuyerera kwemhepo. Kazhinji, mwero wekuyerera kwemhepo unoenderana zvakananga nemwero wekuyerera kwemhepo. Chinhu chepiezoelectric chiri mu detector chinoburitsa chiratidzo chekuchaja chinochinja-chinja chine mwero wakafanana newemhepo. Zvadaro chiratidzo chakadaro chinoendeswa ku intelligent flow totalizer kuti chigadziriswe zvakare.
Michina yekufambisa mvura
Chiyero chekuchinjana chinoyera huwandu hwemvura inoyerera mumudziyo semubhaketi kana stopwatch. Kuyerera kwemvura kunogona kuverengerwa nechiyero chehuwandu nenguva. Kuzadza nekudurura mabhaketi nguva dzose kunodiwa kuti kuyerwe nguva dzose. Piston metres, oval gear metres uye nutating disk meter zvese mienzaniso ye positive displacement metres.
Kubva pama "flowmeters" anochinjika kusvika kuma "Coriolis" akanyatsojeka uye "ultrasonic metres", mhando yega yega yakagadzirirwa kusangana nezvinodiwa zveindasitiri. Kunyangwe uchida kugadzirisa magasi, mvura, kana utsi, pane mhinduro yako. Tora danho rinotevera rekuvandudza mashandiro e "system" yako nekutsvaga nhungamiro yenyanzvi.Taura nesunhasi kuti muwane mutengo wemahara, usina chisungo, uye ngatikubatsirei kuwana flow meter yakakwana yekushanda kwenyu!
